Drill America nACo Blue Annular Cutter

This Drill America annular cutter features an nACo Nano-Composite Blue coating designed to increase tool life by up to 30 percent over traditional HSS cutters. It is built from M2 high-speed steel and cuts only the necessary material for fast, efficient hole making. The 3/4 inch Weldon shank fits most magnetic drill presses and a pilot pin is included.

Suited for Magnetic Drill Press Users

This accessory is intended for operators who use magnetic drill presses, also known as mag drills, to cut steel, cast iron, heated steel and stainless steel. It is not suitable for anyone needing to use a standard hand drill or a conventional drill press. Buyers requiring a different shank style or a cutter for non-magnetic-drill applications should look elsewhere.

3/4 Inch Weldon Shank Compatibility

The single specification that determines fit is the 3/4 inch Weldon shank, which matches the chuck on most magnetic drill presses. Verify that your machine accepts this shank type before purchase. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I fit the 3/4" Weldon shank into my magnetic drill press, and what step causes alignment issues?

Insert the shank fully into the arbor, tighten both set-screws on the flat, then seat the supplied pilot pin before starting the cut — skipping the pin lets the cutter wander.

What part will need replacement first on the nACo coated cutter?

The pilot pin wears faster than the coated flutes; keep spares and swap it when the tip rounds off or the cutter stops self-centring.

At what point does heat become the limiting factor during continuous drilling?

The nACo Nano-Composite coating raises heat resistance by roughly 30 %, so the cutter stays sharp longer, but sustained feed pressure without coolant will still overheat the M2 HSS body first.
