Chip-Clearing Carbide Drill Bits
The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. For the highest accuracy and longest tool life, these solid-carbide bits are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling. All are jobbers’ length so they have the rigidity and length required for most applications.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Ball-End Driver Shafts
Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.
