How do you attach a hole cutter to a drill?
Use the correct arbor or adapter for your drill type. For annular cutters, you’ll typically use a Weldon shank adapter in a magnetic drill.
How accurate is an annular cutter?
Very accurate—most produce holes within ±0.005" tolerance when used in a stable setup with proper feed and speed.
Do annular cutters need a pilot hole?
No. Annular cutters use a pilot pin that helps center the cut and eject the slug. A separate pilot hole is not required.
Can you use an annular cutter in a hand drill?
Not recommended. Annular cutters are designed for use in magnetic drill presses or rigid setups. A hand drill can’t provide the stability and torque needed for safe, accurate cutting.
