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.
These metric bits are ideal for drilling holes for bookcase fittings. Set of eight includes 3, 4, 5, 6, 7, 8, 9 and 10mm bits.
Shanked to size.
Also available in Imperial sizes.
