Drill America nACo Annular Cutter

The Drill America ANC5-530-378 is a 1-15/16 inch by 3 inch annular cutter built for magnetic drill presses. Its nACo Nano-Composite blue coating extends tool life by up to 30 percent over traditional high-speed steel cutters. The M2 high-speed steel body removes only the necessary material for fast, accurate hole making in steel, cast iron, and stainless steel.

3/4 Inch Weldon Shank Mounting

A 3/4 inch Weldon shank locks securely into most magnetic drill presses, also known as mag drills. The shank design prevents slippage during heavy feed rates and allows quick tool changes without extra hardware. The cutter is not compatible with standard hand drills or conventional drill presses and includes a pilot pin for proper alignment.

Upgrade From Uncoated HSS Cutters

Shops replacing uncoated high-speed steel annular cutters gain longer edge retention and better heat resistance when cutting difficult alloys. The jump is worth it for production runs in hardened or stainless materials where frequent cutter changes slow workflow. Buyers needing larger diameters or different cutting depths will need separate tooling.

Questions about this item

What does the nACo Nano-Composite coating do for the cutter?

The nACo Nano-Composite Blue coating increases tool life up to 30% compared to traditional HSS annular cutters and offers extra protection against tool wear and high heat when cutting steel, cast iron, heated and stainless steels.

What shank size does this cutter use and what equipment does it fit?

It has a 3/4" Weldon shank that fits most magnetic drill presses, also called mag drills, and is not for use with a standard hand drill or drill press.

How is the pilot pin used during installation?

The included pilot pin centers the annular cutter in the magnetic drill press before cutting begins; the step people miss is inserting the pin fully so it retracts correctly and allows the cutter to engage the workpiece.
