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.
Sets include cutters, a pilot pin, and a hex key. Also known as annular cutters.
These cutters are perfectly sized for cutting holes that will be tapped later. 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.
