Blue nano-composite coated annular cutter with Weldon shank and pilot pin

Drill America

Drill America ANC5-530-121 3/4" X 1" nACo Blue Annular Cutter

SKU CH-WPT9-WJHVV

The nACo Nano-Composite Blue coating extends tool life by up to 30% over standard HSS cutters for fast, efficient holes in steel, cast iron and stainless using a magnetic drill press

  • nACo Nano-Composite coating extends cutter life by up to 30% over standard HSS annular cutters
  • Cuts steel, cast iron, heated and stainless steels efficiently with minimal material removal
  • nACo Nano coating provides extra protection against wear and high heat during demanding drilling
  • 3/4" Weldon shank fits most magnetic drill presses for secure, quick-change installation
  • Includes pilot pin for accurate hole alignment and immediate use with mag drills

Purpose & Fit

This annular cutter is built for magnetic drill presses and creates 3/4 inch diameter holes with a 1 inch depth of cut. The 3/4 inch Weldon shank fits most mag drills directly. It is not compatible with standard hand drills or conventional drill presses.

Heat, Noise & Power

The nACo Nano-Composite blue coating reduces friction and protects the M2 high-speed steel from excessive heat during cutting. By removing only the necessary material, the cutter lowers the load on the magnetic drill motor. No noise or power-draw figures are provided for the accessory itself.

Upgrade Path

The coating extends tool life by up to 30 percent compared with traditional HSS annular cutters, making the step-up worthwhile when cutting difficult materials such as stainless steel, cast iron or heated steels. The included pilot pin ensures immediate centering. Buyers who need a different hole diameter or cutting depth should select a matching cutter size.

Questions about this item

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

Insert the shank fully into the mag-drill arbor until it locks, then secure the pilot pin so it engages the cutter’s centre hole; skipping the pilot pin causes the cutter to wander and overheat.

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

The pilot pin wears faster than the coated cutting edges; replace it when the tip rounds off or the spring loses tension to keep the cutter centred.

At what point does heat become the limiting factor during sustained cutting with the nACo coating?

The nano-composite coating extends life up to 30% by resisting wear and high heat, but continuous heavy feed in stainless or heated steel will still raise tip temperature until the coating’s protection is exceeded.
