7/8" nACo Annular Cutter

This Drill America ANC5-530-327 annular cutter features a 7/8" diameter and 3" depth of cut with nACo Nano-Composite blue coating. The m2 high-speed steel construction cuts only the necessary material for fast, efficient hole making in difficult metals. It includes a 3/4" Weldon shank and comes with a pilot pin for magnetic drill press use.

Suited for magnetic drill press work

This accessory is designed for operators using magnetic drill presses who need to cut steel, cast iron, heated or stainless steels. The nACo coating increases tool life up to 30% compared to traditional HSS annular cutters. It is not for buyers needing a hand-drill or standard drill-press bit, nor for those without a magnetic base machine.

3/4" Weldon shank fit

The cutter uses a 3/4" Weldon shank that fits most magnetic drill presses, also called mag drills. This shank interface is the single specification that decides compatibility with your machine. Do not use with a standard hand drill or drill press.

Questions about this item

How do I install the 3/4" Weldon shank into my magnetic drill press, and what is the common mistake?

Align the shank flats with the chuck set screws and tighten both screws evenly; the frequent error is securing only one screw, which lets the cutter spin off-centre.

What maintenance or replacement will the nACo Nano-Composite coating and pilot pin require later?

The coating cannot be re-applied; replace the cutter once the blue layer wears through to the M2 high-speed steel, and swap the pilot pin whenever its tip rounds over or no longer centres cleanly.

What limit appears first during sustained cutting in stainless steel?

Heat buildup at the cutting edges is the first constraint; the nACo coating extends life by roughly 30 per cent, but prolonged high-temperature work will still dull the M2 substrate faster than in mild steel.
