Hollow-Core Cutters for Magnetic-Base Drills

Use these cutters with magnetic-base drills. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. Also known as annular cutters.

High-Speed Steel—High-speed steel cutters have a bright finish and are for general purpose cutting.

Titanium Nitride (TiN)-Coated High-Speed Steel—Titanium nitride (TiN)-coated high-speed steel cutters last longer than uncoated high-speed steel.

Cobalt Steel—Cobalt steel cutters offer better heat and abrasion resistance than high-speed steel.

Carbide-Tipped Steel—Carbide-tipped steel cutters last longer than high-speed steel and cobalt steel cutters and are for high-volume cutting of difficult-to-machine materials. Note: These cutters are more sensitive to shock and vibration compared to other cutters and should not be used with Jancy magnetic-base drill model USA101.

Hollow-Core Cutter Pilot Pins—Pilot pins align the cutter and eject the slug. They're also known as ejector pins.

Hollow-Core Cutter Arbor Adapters

You can also pair the cutters with an arbor adapter (sold separately) when using a manual drill press or milling machine.

For Carbide-Tipped Cutters—Arbor adapters for carbide-tipped steel cutters come with a pilot pin.

Round Shank—Arbor adapters for a round shank fit a drill chuck or an R8 collet on a milling machine.

Morse Taper Shank—Arbor adapters for a Morse Taper spindle are for use on a drill press.

Tap-Size Hollow-Core Cutters for Magnetic-Base Drills

These cutters are perfectly sized for cutting holes that will be tapped later. Use them with magnetic-base drills. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. They're also known as annular cutters.

Hollow-Core Cutter Pilot Pins—Pilot pins align the cutter and eject the slug. They're also known as ejector pins.

Hollow-Core Cutter Kits for Magnetic-Base Drills

Kits include five cutters, a pilot pin, and a hex key. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. For use with magnetic-base drills. They're also known as annular cutters. Pilot pins align the cutter and eject the slug. They're also known as ejector pins.

Stack-Drilling Hollow-Core Cutters for Magnetic-Base Drills

The geometry of these cutters allows you to cut aligned holes in multiple sheets at one time. Use them with magnetic-base drills. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. They're also known as annular cutters.

Hollow-Core Cutter Pilot Pins—Pilot pins align the cutter and eject the slug. They're also known as ejector pins.
