1-11/16" HSS annular cutter

This high-speed steel annular cutter produces a 1-11/16" diameter hole with a 1" depth of cut. It is engineered for magnetic drill presses using a 3/4" Weldon shank. The tool suits metalworkers who need fast, efficient hole making in structural steel or plate.

Weldon shank limits mounting options

The 3/4" Weldon shank locks into magnetic drill presses only and cannot be used with standard hand drills or conventional drill presses. High-speed steel construction balances hardness and toughness for general-purpose wear resistance. This mounting constraint defines the workflow for every job.

Pilot pin included for centring

A pilot pin is supplied with the cutter to align the tool and eject the slug after each cut. No additional accessories or software are bundled. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item

What does the 3/4" Weldon Shank interface mean for tool compatibility?

The 3/4" Weldon Shank fits only magnetic drill presses. It will not work in a standard hand drill or conventional drill press.

What physical dimensions must my magnetic drill press accommodate for this cutter?

The cutter is 1-11/16" in diameter with a 1" depth of cut. Your mag drill must accept a 3/4" Weldon Shank and have enough stroke for the full depth.

How is the pilot pin used during installation, and what step is often missed?

Insert the supplied pilot pin into the cutter before mounting it in the mag drill. The pin centres the cut and ejects the slug; forgetting it leaves the hole off-centre and the slug stuck inside.
