The COMOWARE Cobalt Drill Bit Set is one of our early entries, and it is popular with both fans and professionals. Many people choose it because of its multi-functional benefits. It also has a good combination of durability and capabilities.
These were purchased to replace a few of damaged bolts in patio furniture. We couldn’t finish a single hole. Despite using cutting oil as a lubricant and using a regulated RPM to avoid scorching the bits, both of the 1/8″ bits immediately dulled.
This drill bit set has exceeded my expectations. It contains all of the sizes that We require for everyday use. It drills really well. The quality is excellent. The pricing is fantastic! This is something We would suggest to everyone.
So far, the pricing and quality have been satisfactory. In comparison to the ones We usually buy at Home Depot, I’m pleased with the drilling performance.

- Can be used on hard materials
- Holder case helps keep things organized
- Not much color variation
This is a fantastic set of drill bits. It sliced through hardened 1/2″ steel like butter.
Always proceed slowly and use curtting oil. Keep the bit and the metal from getting too hot. It also works on wood, but just the cheapest portions. When drilling steel, you want excellent tools. This is a lime.
It’s important to note that some sections are difficult. Everything that is hard is fragile. Take it easy and you’ll be fine.
The pieces are fantastic and will last a long time. We have a vast collection of low-cost parts. Trying to drill through 1/4″ plate and concrete for tapcons over my head. These made the task a hundred times simpler.
This was money wisely spent. Negative reviews might be the result of poor drilling; steel = slow and high pressure with oil or any bit, regardless of quality, will be ruined.
- Functions effectively
- Durable item
- Does not skid
- Makes tough applications easy
- Customer care service needs to be improved
Wow, after reading the reviews, Certain that no review, good or negative, is worth 100% of your time unless it’s a one-star rating. Because they are so frugal with their money, many people nowadays submit exaggerated or truly harsh evaluations.
To be honest, the pricing for this item is reasonable; yet, everyone wants a lower price in order to receive the greatest ratings. For the price, We think it’s a terrific deal. You’ll know what’s up if an item is too inexpensive or too good to be true.
My ex-husband owns two Dewalt drills but has never purchased any bits and just has a handful that he gathered from various sources. Or perhaps he did purchase some. He has a habit of dumping items wherever he’s finished with them. He’s misplaced his hammers. How do you lose a hammer in the first place? Not to mention hammers…
We’ve been unsuccessful in drilling into the super-strong steel of my hotrod’s boxed frame rails. Old bits honed on my Drill Doctor were simply not cutting it. These pieces got the job done swiftly.
- Designed exceptionally well
- Affordable price
- Minimizes spinning
- Does not break easily
- Quality of the case is not good
The blade is made of soft steel that has been inadequately sharpened. The point geometry was quite inadequate (in fact, due to a backward slanted cutting edge, it could not have cut) and had to be reground.
However, even once a good point was created, the steel was too soft to cut into a standard bolt without soon softening to the point where it could no longer be cut. With the 7/32 bit, penetration was perhaps 1/16 inch before it stopped cutting. I cut with cutting oil and keep the bit moist.
An exact replica of the gold-colored Dewalt bits. When you look at it, you’ll see the lack of lustre and understand it’s rubbish. Trying to remove broken transmission case bolts, We broke two medium pieces.
It was slicing through before breaking off with ease. Furthermore, even after a through-cut, It was unable to remove the bolt; the parts were becoming increasingly huge, and We eventually struck the threads.
- Premium design
- Made of high-quality material
- Completely prevents walking
- Works fast
- Tends to get jammed
As things were, We needed to drill a 7/8-inch hole in a 1/4-inch steel plate that had previously been a 3/4-inch hole. We figured the #5 bit would suffice because the last and greatest step is 7/8. All We had to do was sharpen the hole from 3/4 to 7/8 inch in diameter.
We used a nice cutting oil and breezed through the first three cuts. Then it grew worse on the fourth hole, and the fifth hole was nothing but smoke. We believe these are suitable for thinner, softer metals and wood, but not for heavier materials.
The CO-Z SDB-0000 5pcs Hss Cobalt Multiple Hole 50 Sizes Step Drill is without a doubt one of the most useful equipment for professionals. This item is a terrific partner for successful project delivery in projects where a single millimetre may make or break it. It’s one of those rare findings that works admirably and is available at a bargain price.
Very beautiful collection, well-protected in its box. We got it today and tried it out because going to use it this weekend. It’s a nice, crisp cut with no hesitancy. If they hold up, only time will tell. We didn’t see much information regarding the case, but it appears to be overkill.
Looks like a Barbie doll steamer trunk; heavy-duty metal casing with a firm clasp at the corners. The parts are held in place by dense foam on the inside, while a layer of softer foam is bonded to the upper lid. The case measures 6-1/8″ x 4-1/8″ x 1-5/8″ when closed. For not a lot of money, this is a nice set.

It was replacing an exhaust manifold when one of the bolts snapped. To drill through hardened metal, We required a bit. We decided to give these cobalt pieces a try after reading about them. The bolt is still there after four bits.
They were dull within minutes, even after applying oil to guarantee they didn’t overheat. Sure, they’d work for lesser things, but don’t count on them for anything major.
For the price, this is a good drill kit. This is the second set We’ve made. Over the course of several years, we grind the first set to nothing in a part-time fab shop.
They’d already been sharpened. You may still sharpen the old set, but for our purposes, a fresh set every few years is sufficient.
We had no idea there was such an excellent drill available! This drills so smoothly and cleanly that it must be a drill from heaven! Since using this drill bit, the food has tasted even better!! My wife responded yes when We asked if she wanted to drill with me. After that, we drilled together!! In the previous 20 years, we have rarely spoken!! The only thing we want to do now is drill!
In an inexpensive acoustic guitar, We was changing the tuners. For those, We required larger holes, therefore We needed a strong sharp bit that was just the proper size.
It did an excellent job of cutting the holes. We only wish We had begun at the rear of the headstock since there was a small amount of tearout.

- Durable and sturdy
- Provides good grip
- No grit or residue
- Packaging needs to be improved
The latest drill bits on the market today are HORRIBLE in comparison to the ones We’ve purchased and used over the years. Particularly in the SMALL sizes. We tried Bosch, Dewalt, and other brands, but they were useless. They are a swindle.
We’ve been working on a van makeover that necessitates a lot of drilling into the inside metal and supports. We ‘ve drilled a lot of holes, and none of them have dulled or broken. That’s saying a lot considering a tool snob who gets irritated easily.
We got these drill bits to use as a grill vortex by drilling a few holes in the bottom of a stainless steel utensil caddy. We’d blunted four bits, snapped one, and drilled only five little holes in less than five minutes.
Excellently constructed 5% cobalt drills that easily drill through non-hardened steel and are highly sturdy and long lasting on wood, plastic, and other materials of similar composition.

It may be suitable for plastic, wood, and aluminium, but it is unquestionably insufficient for steel. My drill bits are normally purchased from Lowe’s or Home Depot, and they perform the job well and last a long time. We work as a locksmith, drilling locks and metal door frames for lock installations.
The first time We tried to drill a security door frame with these drill bits, they broke. Before We finished my job, the majority of them merely snapped off one by one.
We got this kit specifically for the components that We needed. When I first obtained these drill bits, We utilised the ones We required and enjoyed them so much that We got rid of the others. From now on, We’ll be utilising these drill bits. We ‘ll recommend these to anyone who works with drill bits for a living or makes home renovations.

The EFFICERE 8-Piece 1/2′′ Shank Silver and Deming Drill Bit Set is a garage must-have. If you need to drill big holes in hard metal surfaces like copper, sheet metal, or other materials, this is the tool to use.
We only gave them four stars since We haven’t used them much yet. We had no trouble drilling a 1″ hole in 3/4″ mild steel flat bar using a 3/16 pilot hole at roughly 200 RPM and plenty of cutting lubricant.
We confident they’ll suffice for my occasional usage needs, which don’t justify spending hundreds of dollars on a professional quality set. Simply ensure that your drill press has the capacity and modest speeds necessary to handle the bigger bits.
Drilling holes in 1/8″ non-tempered 2″ square tubing, the tips snapped and the drills bent. A 1/4″ drill bit was used to pre-drill the holes. My husband was drilling with a high-octane drill that had a huge stabilising handle. The pieces didn’t even come close to meeting the star rating. Disappointing and aggravating. We intend to return. The one star is for the promptness with which the hotel arrived.
- Lasts for long
- Can work on hard metals
- Brilliant design
- Works fast
- Case quality is not up to the mark

This is the ideal drill bit for drilling stainless steel screws since stainless steel is a very hard metal. Do not purchase titanium coated hard steel since it will become dull in a matter of seconds.
These bits are good quality, however We wish there were more carbide bits readily available; these bits are worthless for hardened steel or security grade steel. This isn’t good enough for me. Even a cobalt concentration of 8% is insufficient. A carbide masonry bit works better for me.
It was looking for something to drill into stainless steel, and this was it!

What to Consider When Choosing the Best Drill Bits for Stainless Steel
Not all bores accomplish the same thing. To recognize the best boring apparatus for treated steel, finding out about qualities like material, covering, recurrence of purpose, and bore number is basic. Peruse on to gain proficiency with the elements to consider as you look for the best bores for your tasks that include hardened steel.
Treated steel is an incredibly hard material. Low-carbon steel bits, similar to those used to penetrate into wood, don’t perform when applied to hardened steel. Accordingly, a bore for use with treated steel requirements to really be more diligently than the prepare itself.
One way that producers accomplish this hardness is by implanting materials that work with infiltration and safeguard against overheating.
Carbide is one such material found in boring apparatus for tempered steel. Titanium and tungsten carbide are close to as hard as precious stone, making them ideal for entering steel.
Mixing boring tools with cobalt is another way that producers accomplish ultrahard bores. Rapid steel, otherwise called HSS, is the most widely recognized boring tool for metal applications. Cobalt pieces are an augmentation of HSS bits.
They fuse a component with between 5% and 8 percent cobalt that makes the boring apparatus harder than a commonplace HSS touch and in this manner appropriate for accuracy penetrating in treated steel and other hard materials.
Numerous makers supplement development materials like boring apparatus with metal coatings. These coatings advance entrance and assurance of the boring tool. Dark oxide coatings lessen grinding and hotness a huge thought while penetrating metals. Dark oxide likewise safeguards against consumption and water, keeping the boring tools useful for a more drawn out timeframe.
Titanium Nitride (TiN) safeguards high velocity boring tools. Particularly for their brilliant shading, TiN-covered boring tools are great for high velocity drills. The covering gives the auxiliary advantage of being ultradurable, causing them an astounding incentive for purchasers who plan high-recurrence use.
Titanium Carbonitride (TiCN) is possibly the most tough metal covering accessible. TiCN pieces are blue-dim in shading. Their covering makes them inconceivably impervious to wear and equipped for suffering high velocity and high-recurrence use.
On account of its hardness, treated steel is an unforgiving development medium. As a rule, there is just a single opportunity to accomplish the ideal drill opening.
Boring tool numbers are connected with wire measure size. The bigger the piece number, the more modest the measurement of the subsequent opening. For instance, a number 80 bore makes an opening with a breadth of 0.0135 inch.
As the measurement develops bigger, the piece number becomes more modest. For instance, a number 1 boring tool has a measurement of 0.2280 inch.
Rapid metal boring makes inordinate rubbing and hotness. The additional pressure put on standard bores will in general break them down rapidly. People who expect to penetrate tempered steel as often as possible ought to make certain to purchase bits planned considering life span.
Notwithstanding ultrahard materials and defensive coatings, bore clients who look for life span ought to guarantee the piece can be honed. While boring apparatus imbued with carbide or cobalt keep their edge longer than a standard piece, putting resources into a set for life regularly implies resharpening the dull boring tools after some time.
Nonetheless, the strength that makes hardened steel so well known additionally makes it challenging to penetrate into with standard boring apparatus.
Boring apparatus worked to chip away at gentler material, similar to wood, will not get the job done against treated steel. Fortunately, makers reason plan exceptional bores fit for penetrating even the hardest grade of treated steel.
Producers utilize more than one strategy to make these ultrahard boring apparatus, and they each enjoy benefits and drawbacks. This guide investigates the various characteristics of these particular sorts of bores and surveys the absolute best boring tools for hardened steel accessible today.
