Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.
These jobbers'-length bits have the rigidity and length required for most applications.
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length drill bits.
Use these bits for general purpose drilling in most material.
With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life.
Carbide-tipped bits maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.
Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit.
Use these inch size cutters with magnetic-base drills.Also known as annular cutters.
These cutters are perfectly sized for cutting holes that will be tapped later. Also known as annular cutters.
Sets include cutters, a pilot pin, and a hex key. Also known as annular cutters.
Use these metric cutters with magnetic-base drills. Also known as annular cutters.
The geometry of these cutters allows you to cut aligned holes in multiple sheets at one time. Also known as annular cutters.
