Annular Cutters
Available13 products
Annular cutters install into magnetic-base drills, drill presses, and milling machines to make smooth-walled, burr-free holes in one pass. They use less power, create less torque, produce fewer chips, and drill to closer tolerances than standard twist drill bits. They also do not require predrilling or step drilling. Annular cutters have a hollow core surrounded by teeth that cut through the perimeter of the hole during drilling, leaving a solid slug in the center. They also have flutes that pull chips out of the hole during drilling and a pilot pin that centers the cutters and allows coolant to flow to their tip during drilling. Arbor adapters are required when using annular cutters with drill presses and milling machines.

High-Speed Steel Annular Cutters for General Cutting
High-speed steel annular cutters are the standard choice for general purpose drilling applications. They create smooth-walled holes in a variety of materials.

One-Piece Alternate-Tooth Carbide-Tipped Annular Cutters
These one-piece annular cutters feature an alternate-tooth geometry on their cutting edge that allows them to make holes faster than standard annular cutters. They create accurate, smooth-walled holes in steel, stainless steel, and cast iron up to 1/2" thick. These cutters have carbide-tipped teeth that provide more wear resistance and heat resistance and retain their hardness for longer than high-speed steel or cobalt teeth. They also have a three-flat shank that installs into standard three-jaw chucks.

Extended-Reach Annular Cutters
Extended-reach annular cutters install into handheld drills and provide more length for drilling in areas where standard annular cutters cannot reach. They are typically used for installing trailer hitches or making holes in pipe and tubing in a single pass.
