Carbide Drill Bits
![]() |
Jobbers' Length Round Shank |
The hardest and most wear-resistant drill bits you can buy. Carbide bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
Uncoated—Excellent for a range of materials but won't last as long as coated bits.
