Chip-Clearing Cobalt Steel Drill Bits
 |
Jobbers' Length Parabolic Flute Round Shank |
 |
Split |
Avoid clogs and dissipate heat with cobalt bits that last at least twice as long as high-speed steel. The flutes clear chips to improve coolant flow and prevent damage to the bit and the hole. They also speed up drilling since you don't have to stop to clear the bit manually.
Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
Uncoated—Polished to eject chips, these are also known as bright finish bits.

Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods
 |
These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
