Built for Durability

Bosch titanium-coated drill bits offer the best durability and speed for general-purpose drilling applications. They're best for drilling holes into metal, but work equally well for wood and plastic. Use in steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, composite materials and common stainless steel.

Brute Tough Case

Bits stay safe in a Brute Tough case. The case is small enough to keep in your pocket or tool belt, yet tough enough to withstand hitting hard materials on the job. Case contains 18 bits.

Titanium-Coated for Heavy-Duty Applications

Built for heavy-duty applications, titanium-coated bits last up to six times longer than high-speed steel bits. Their speed helix design enables for three times faster drilling than standard bits.With a surface hardened to penetrate tough materials including stainless steel, these bits are availble in jobber length with 3/8" reduced shank. Bits 3/16" and larger feature 3-flats Shank; smaller bits have standard round shank. Bits 3/16" and larger have 135º split point, which offers two cutting edges and requires less force. All bits range in size from 1/16" to 1/2".

Warranty Information

It is backed by Bosch's one-year limited warranty, 30-day money back guarantee, and one-year service protection plan.

Outstanding set of self starting bits. I work with industrial fabrication and have to drill in all sorts of steel. This bit set lasts 10 times longer than most sets, I have not found any out there that can compare.

These drills self start without walking, and drill with almost no pressure. However that is the catch. You CANNOT press hard on these bits, they will shatter the tips. You can have hard, or you can have flexable / tough. Hard stays sharp. Tough tolerates abuse, but dulls quickly. If you use these drills, set your drill chuck to screw and set the tork to slip on the smaller bits or the drills will chip as they break through the material. If you take care of these bits they will last you. Once I learned to set the slip clutch these bits seem to last forever! Best drill bits on the market, the only brand I will use.

And as proof of how tough they are, these cut stainless. Again and again. Try that with a hardware store bit!

I could not find my drill bits anywhere which cost $50 when purchased about 20 years ago. This set was nearly 50% less expensive for more bits and the same titanium coating. Also the new anti-skating feature is much appreciated. They cut really well. It is a good product for the price.

5.0 out of 5 stars Best basic set October 15, 2008
By Ben
Verified Purchase
Amazon lists this set as TI118 but on the box I received was model TI18. No complaints here though, the case is slighty more rectangular but smaller. One nice feature I didnt expect were 3 hex slots on the bit holder, very convenient you can throw in a few driver bits along with the drill bits. More importantly the bits are Made in USA, to be more specific it says "Fabricated in USA of Austrian Steel". On those two points, I would recommend this set over others for the convenience and quality.

5.0 out of 5 stars Well thought out basic set November 12, 2010
Must be a new/revised set - Bosch site not showing TI21 set. Case now similar to Bosch TI13 set except with 3rd red fold out, and package now says, "Made in China" (as does other sets in this price range).

Has best features of other basic sets looked at. Set is 1/16-1/4 in 64ths plus 5/16, 3/8, and 1/2. (For some reason this and most other basic sets have dropped the 7/16 bit.) Set has 2 ea of 1/16 thru 1/8 most used for pilot drilling. 9/64 and above are split point ground to reduce wandering at hole start. 3/16 and above are ground w/ 3 flats on shank to eliminate spinning in 3-jaw chuck. 1/2 bit has reduced shank to fit 3/8 chucks. Case closes to solid compact pkg. When open, 3 foldouts give access like a regular drill index case. Titanium coated bits ground sharp and run true.

To rectify the common cost-cutting fad of dropping the 7/16 bit from a basic set, I bought an individual Bosch 7/16 bit, also with a reduced shank to 3/8(At $12 for one drill bit!), removed the 15/64 bit from the case, moved the 1/4, 5/16, and 3/8 bits down one hole location, drilled the 3/8 location over-sized with the 7/16 bit and then put the 7/16 bit in the former 3/8 location. Although technically missing the 15/64 size, set now seems more "complete" for the larger drill diameters.

Sent as a gift to a rural overseas site-so set needed to be of reputable quality but not able to report on long-term durability yet.

5.0 out of 5 stars great drill bits September 30, 2010
By Steve O

This is my second set of these drill bits and I learned on the first set to not be to aggressive with the downward force on the bits -- medium force is all you need with these bits and the extremely sharp bits will do the rest. The price was super compared to the big box home centers, delivery was on time -- what else do you want?

4.0 out of 5 stars Workhorses, but sometimes break easily September 17, 2013
By Ryan
Verified Purchase
These are my main drill bits for wood, metal, and plastic in my home shop and in construction. They drill well through almost anything and don't walk too much.

Unfortunately, they're another casualty in my war against cast-steel things. These are cast steel, not milled billet steel. They snap when bent and lose their edge painfully fast if they so much as touch cinderblock. They will also be very hard to re-sharpen. The smallest bits (upper right in the picture) break very easily even under the dead weight of heavier drills.

I have mixed feelings, but they have served me well. I recommend them, with the caveat that you know their limits and take care of them.

I wanted to replace the fire tray in an outdoor fire pit with something more durable, so I got a sheet of stainless and used these for the drilling. No complaints.
