Carbide Drill Bit Sets
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 applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.
Uncoated drill bit sets are good for general purpose drilling in most metal and plastic.
Titanium-carbonitride (TiCN) coated drill bit sets have a hard, smooth finish that resists chipping and wear. It also prevents material from accumulating on the cutting edge. They’re especially good for use on aluminum.
Aluminum-titanium-nitride (AlTiN) coated drill bit sets are the most wear and temperature resistant for the longest life and highest drilling speeds.
