Description of Bosch TI18 18-Piece Titanium Twist Drill Bit Assortment with Plastic Case

Bosch titanium drill bits offer the best durability and speed for general-purpose drilling applications. While the hardness of their titanium nitride coating protects the bits from chipping and cracking, the lubricity defends the bits from heat buildup--the number one cause of product failure. Bosch titanium drill bits last six times longer than black oxide bits. And their speed helix design allows them to penetrate materials three times faster than standard bits, which means extended battery life for your cordless drill. You can use the bits to drill into steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, composite materials, and common stainless steel. The 135-degree split point starts on contact with no walking or skating, and no center punch is required.

Tools and Hardware Reviews of Bosch TI18 18-Piece Titanium Twist Drill Bit Assortment with Plastic Case

Customer Review: Well thought out basic set
Summary: 5 Stars

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.
