Drill America ANC5-530-110 Annular Cutter

This Drill America annular cutter features a 7/16 inch cutting diameter and a 1 inch depth of cut. It uses an M2 high-speed steel body with an nACo Nano-Composite Blue coating. The 3/4 inch Weldon shank fits most magnetic drill presses. A pilot pin is included for alignment.

nACo Coating Thermals and Tool Life

The nACo Nano-Composite coating increases tool life up to 30% compared to traditional HSS annular cutters. It provides extra protection against tool wear and high heat during cutting. The design cuts only the necessary material for fast, efficient hole making. This reduces power draw and thermal load on the magnetic drill press.

Upgrade From Standard HSS Cutters

This cutter replaces standard HSS annular cutters when drilling difficult materials such as steel, cast iron, heated and stainless steels. The jump is worth it for operators who need longer tool life and better heat resistance. It is not for use with standard hand drills or drill presses. Buyers needing different diameters or depths of cut must select another model.

Questions about this item

How do I install the 3/4" Weldon shank on my magnetic drill press, and what step do people often miss?

Align the Weldon shank flats with the magnetic drill press chuck and secure the set screws; the step people miss is inserting the supplied pilot pin before tightening.

What maintenance or replacement will the nACo coated annular cutter need later?

The pilot pin will wear first and should be replaced when it no longer centres the cutter; the nACo coating itself lasts up to 30% longer than standard HSS before resharpening is required.

What limit appears first during sustained cutting in stainless steel?

Heat buildup at the cutting edges is the first limit; the nACo nano-composite coating delays this, but continuous heavy feed without coolant will still overheat the M2 high-speed steel body.
