JOBBER LENGTH: 11/64-Inch cutting diameter, 2-1/8-Inch flute length, 3-1/4-Inch overall length, 135 degree split point, straight shank. MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits. CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits. APPLICATION: best used for drilling in hard metal, including stainless steel. INCLUDE: 12 pieces of 11/64-Inch cobalt drill bits with case.

Poor Quality Stainless Drill Bits

These industrial and scientific cutting tools looked promising, but after several uses they had already begun to dull and break. The one positive aspect is that the length is adequate for some industrial applications. However, the cons outweigh this one pro as the quality is simply not up to par. Don't waste your money on these subpar industrial drill bits.

Pros
  • Durable, rust-resistant material.
Cons
  • May not fit in smaller workspaces or toolboxes.

quick response and delivery

I have these drill bits purchased for use in installing doors and hardware, bits work great when new unfortunately there is concrete in the door frames and when the bits "touch" the cement they will leak however the beats work as advertised.

Pros
  • JOBBER LENGTH: 11/64" cutting diameter, 2-1/8" flute length, 3-1/4" overall length, 135 degree collet, straight shank
Cons
  • little things

Good quality and price

tube. This pipe is very difficult and difficult to drill. The bits worked fine but dulled quicker than I had hoped. My expectations were probably unjustified. Bits are better kept in a new iron. I have purchased several of these bits in various sizes and will continue to do so.

Pros
  • MADE OF HSS STEEL AND 5% COBALT: Improve the much higher heat resistance due to the high hardness of cobalt steel in red, offer high durability compared to typical HSS drill bits
Cons
  • vanish
