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.

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.
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.
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.
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.
Options span smaller to large-diameter hole-making needs.
Available stated capacities include shallow and deep cutting options.
The range includes high-speed steel and carbide-tipped cutters.
Many represented cutters include a pilot pin to help guide placement.

| Cutter type | What the summaries describe | Selection considerations |
|---|---|---|
| High-speed steel annular cutters | Metalworking cutters with selected models offering pilot pins and resharpenable cutting edges. | Compare required diameter and depth; some options are designed for large holes and deep cuts. |
| Carbide-tipped annular cutters | Cutters for steel, stainless steel, and hard metals, commonly with pilot pins; selected models note clean or burr-free hole finishes. | Match the diameter and cutting depth to the job and choose carbide-tipped edges for the stated material applications. |
| Magnetic-drill-focused cutters | Select cutters for portable magnetic drills, including models with a 3/4 in. double-flatted shank, fluting, and slug-ejection clearance. | Verify compatibility with the drill setup and consider chip movement, mounting connection, and slug handling features. |
Plan the right fit before choosing
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.
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).
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.
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.
