Chip-Clearing Drill Bits
With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. The flutes improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole.
Carbide Jobbers' Length
 |  |
Parabolic Flute | Standard |
The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These 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.
Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.
Parabolic Flute—A U-shaped groove on the flutes cuts faster and clears chips more quickly than high-helix bits, so these are better for drilling deep holes.
Round Shank—The most common shank type fits in a drill press chuck.
Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
