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.

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.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials. These countersinks require rigid tool holding to prevent breakage and are not for use with hand-held tools. The 60° countersink angle is compatible with the profile of centers on a lathe. They have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small gap that prevents damage to the points of live or dead centers. Turn the countersink around for a sharp cutting edge when one end dulls.

TiCN (titanium carbonitride) coated countersinks last longer than uncoated countersinks and are best for general purpose cuts as well as for use on aluminum.

For excellent performance on hard and abrasive materials, these carbide countersinks are harder, stronger, and more wear resistant than cobalt steel and high-speed steel countersinks. They require rigid tool holding to prevent breakage and are not for use with hand-held tools. All have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small pilot hole at the bottom of the countersunk hole to facilitate drilling. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring. When one end of the countersink dulls, turn it around for a sharp cutting edge.
