Description

These are the best brad-point drills we have ever offered for sale.

Starting with a top-of-the-line American-made twist drill, we reshape and sharpen the tips on a state-of-the-art Swiss CNC grinder. Made from high-speed steel, the bits are not subject to burning, and stay sharp about 10 times as long as carbon steel bits.

The polished flutes give superior chip clearance, and the sharply defined lips have a slight negative rake angle on the lip tips to score the hole perimeter for clean entry and smooth sidewalls. Equally important, these bits are extremely accurate in diameter.

Bits from 5/64" to 3/8" are shanked to size.

Bits from 25/64" to 1/2" have 3/8" dia. shanks and bits from 33/64" to 1" have 1/2" dia. shanks.

All are jobber length bits, with overall lengths varying from 2" with 1" of fluting for the 5/64" bit to 6" with 3 3/4" of fluting for the 1/2" bit. All bits over 1/2" are 6" with 3" of fluting.

The set of 12 comes in an indexed steel box and includes sizes 5/64" to 1/4" in 64th increments to cover all clearance and tap holes for screw sizes #2 to #16.

The steel boxed set of 28 includes sizes 5/64" to 1/2" in 64th increments.

The set of seven includes sizes 1/8" to 1/2" (in 16th increments) and comes in a vinyl pouch.

The sets of three and four Imperial bits do not come with boxes or pouches.

Also available in metric sizes.
