Helpful answers

Category Questions

How do I choose the correct Annular Cutters annular cutter?

Match the cutter to the required hole diameter, cutting depth, arbor or shank size, pilot pin, magnetic drill capacity, and the material being cut.

When should HSS, cobalt, or carbide-tipped annular cutters be used?

HSS is a general-purpose choice for many steels, cobalt offers improved heat resistance for harder materials, and carbide-tipped cutters are often selected for abrasive, hard, or difficult materials. Tool speed, lubrication, and manufacturer recommendations remain important.

Why is cutting depth important when selecting an annular cutter?

The cutter must have enough usable depth to pass through the material without bottoming out. Also verify the pilot pin and arbor are correct for the selected depth and cutter series.
