HSS or carbide-tipped?

High speed steel (HSS) annular cutters are the everyday choice for mild steel and structural shapes, and they tolerate the vibration of portable mag drills well. Carbide-tipped (TCT) cutters cost more but cut faster and last much longer in stainless, hardened steel, abrasive plate and high-volume work.

FAQ

What depth of cut annular cutter do I need?
Pick a depth of cut at least as deep as the material you are drilling. A 1 inch (25 to 30 mm) cutter handles plate and flanges up to about 1 inch thick; a 2 inch (50 to 55 mm) cutter covers thicker plate and stacked parts. Longer 3 and 4 inch cutters need a mag drill with enough stroke.

What is the difference between a Weldon shank and a universal shank?
A 3/4 inch Weldon shank has two flats that lock with set screws and fits most magnetic drills. Universal (quick-in) shanks add a groove that also fits quick-change arbors such as Fein and Nitto style. Check your drill arbor before ordering.

Do annular cutters need a pilot pin?
Yes. The pilot pin centers the cutter, ejects the slug and opens the coolant path. Pilot pin length must match the depth of cut, so a 2 inch deep cutter takes a longer pin than a 1 inch cutter.

Should I use cutting fluid with an annular cutter?
Yes. Feeding cutting oil through the arbor keeps the teeth cool, flushes chips and greatly extends cutter life, especially on stainless steel and carbide-tipped cutters.
