Annular Cutters

Annular cutters are hole-making tools for metalworking professionals, maintenance teams, and drill operators. Used for fabrication, installation, machining, and shop or field drilling work, they create round holes in materials such as sheet metal, plate, steel, stainless steel, hard metals, and, for select cutters, plastics. The annular cutting profile removes a material slug rather than producing loose chips throughout the hole.

How to Choose Annular Cutters

Choose an annular cutter by matching the required hole diameter and cutting depth to the workpiece, then selecting a cutter construction and features appropriate to the material and drilling setup. The available range includes compact cutters for smaller holes as well as large-diameter and deeper-cut options for demanding hole-making work.

Use Cases

Make accurate round holes

Annular cutters support hole-making for fabrication, installation, maintenance, machining, and drilling tasks. Options are represented for sheet metal, plate materials, plastics, steel, stainless steel, and hard metals.

How to Choose

Start with size and depth

Match the cutter diameter to the finished hole size and confirm that its stated cutting depth meets the material thickness or hole-depth requirement. Diameters in the range run from 13 mm to 5-1/8 in., while stated cutting depths range from 6.4 mm to 6 in.

Applications

Match the cutter to the material

High-speed steel cutters are represented for metalworking applications. Carbide-tipped models are represented for steel, stainless steel, and hard metals, with several including pilot pins for positioning.

Additional Information

Review tool and operating features

For portable magnetic drill use, confirm shank compatibility where specified; select models include a 3/4 in. double-flatted shank. Other represented features include fluting for chip movement, tapered inner diameters for slug ejection, resharpenable edges, and pilot pins.

Planning Guide

Plan the right fit before choosing

Plan the hole

Confirm diameter and cutting-depth requirements

The cutter diameter determines the finished hole size, while the stated depth of cut defines the supported cutting capacity. Select a size that aligns with the application before comparing cutter material or added features.

  • A 13 mm cutter is represented with a 6.4 mm depth of cut.
  • 24 mm, 33 mm, and 40 mm cutters are represented with 25 mm cutting depths.
  • Larger options include 1-5/8 in., 2-7/16 in., 3-3/16 in., 3-1/4 in., 3-3/8 in., and 5-1/8 in. diameters.
  • Deep-cut options are represented with 2 in., 4 in., and 6 in. cutting depths.
Choose the cutting construction

Compare high-speed steel and carbide-tipped options

High-speed steel annular cutters in the range are designed for metalworking and several have resharpenable cutting edges. Carbide-tipped cutters are described for steel, stainless steel, and hard metals, with durable cutting edges or teeth for those applications.

  • Select high-speed steel when the represented construction and resharpenable-edge feature fit the metalworking task.
  • Consider carbide-tipped teeth or tungsten carbide tips for represented work in steel, stainless steel, and hard metals.
  • Check material limitations where provided; one 1-5/8 in. high-speed steel cutter is stated for materials up to 275 BHN (28.5 HRC).
Consider positioning and drilling setup

Look for guidance, mounting, and chip-handling features

Pilot pins are included with many represented cutters and help guide or position the cutter for more controlled and precise hole placement. Certain magnetic-drill cutters also include shank, fluting, and inner-diameter features intended to support mounting, chip movement, and slug ejection.

  • Pilot-pin models help support accurate positioning during hole-making.
  • A 3/4 in. double-flatted shank is specified on select cutters for compatible magnetic drills.
  • Fully fluted bodies help move chips away from the cutting area.
  • A tapered inner diameter on one model provides clearance to support slug ejection.
FAQ

Common questions before buying

What materials can annular cutters be used on?

Represented applications include sheet metal, plate materials, plastics, steel, stainless steel, and hard metals. Material suitability varies by cutter.

How do I select the right annular cutter size?

Match the cutting diameter to the required finished hole size, then confirm that the stated depth of cut meets the hole-making requirement.

What is the benefit of a pilot pin?

A pilot pin helps guide or position the cutter for more controlled and precise hole placement.

Are resharpenable annular cutters available?

Yes. Several high-speed steel cutters in the range have resharpenable cutting edges, allowing the edges to be renewed for continued use.
