What the AI looks for in Annular Cutters
- Shank
- 3/4" Weldon is the most common standard; confirm against your drill (some Fein and universal quick-change arbors differ) A cutter that does not fit the arbor is useless without an adapter.
- Depth of cut
- Choose 1" or 2" nominal depth to exceed your material thickness A cutter that is too shallow cannot finish the hole through the plate.
- Cutter material
- HSS/cobalt for mild steel; TCT for thick, hard or abrasive steel and higher production TCT lasts much longer but chips if the setup is not rigid.
- Pilot pin
- Use the pilot pin made for that depth and shank It centers the cut and ejects the slug.
Brands that matter
- Hougen: Originator of annular cutting and a broad range.
- Milwaukee: Cutters matched to its mag drills.
- Fein: Mag drills and cutters, check its shank system.
- Jancy: Slugger brand mag drills and cutters.
What to avoid
- Using annular cutters in a handheld drill
- Dry cutting without cutting fluid
- Mixing pilot pins across cutter depths
Questions
Can I use annular cutters in a drill press?
