Blue coated annular cutter with Weldon shank and pilot pin

Drill America

Drill America ANC5-530-369 1-3/4" X 3" nACo Blue pneumatic accessory

SKU CH-HFB2-3A9JW

A nACo Nano-Composite coated annular cutter that extends tool life up to 30% while cutting steel, cast iron and stainless steel on magnetic drill presses

  • nACo Nano-Composite coating extends tool life up to 30% over standard HSS
  • Cuts steel, cast iron, heated and stainless steels efficiently
  • Nano coating resists wear and high heat during operation
  • M2 high-speed steel removes only necessary material for fast holes
  • 3/4" Weldon shank fits most magnetic drill presses

Tool purpose and fit

This annular cutter is built for magnetic drill presses only, using a 3/4" Weldon shank that locks into most mag drills. It removes only the perimeter of the hole, so less material is wasted and cutting is faster than a twist drill in steel, cast iron, heated steel and stainless steel. The tool ships new and includes the required pilot pin for immediate use.

Coating advantage and upgrade point

The nACo Nano-Composite Blue coating extends tool life by up to 30% over traditional high-speed steel annular cutters, while the coating adds extra resistance to wear and high heat. Switching to this cutter makes sense when you need longer intervals between tool changes on tough alloys or when heat buildup shortens the life of uncoated cutters.

Ideal users and limits

Fabricators and maintenance crews running magnetic drill presses on structural steel or stainless will benefit from the faster cuts and reduced wear. It is not suited for operators without a mag drill, for jobs requiring a standard drill press or hand drill, or for applications where the California Proposition 65 chemical warnings are a compliance concern.

Questions about this item

What shank size does the Drill America ANC5-530-369 annular cutter need to fit my magnetic drill press?

The cutter has a 3/4" Weldon shank that fits most magnetic drill presses, also called mag drills.

How do I install the cutter correctly, and what step do people often miss?

Insert the supplied pilot pin into the cutter before mounting it in the magnetic drill press; the pin aligns the cut and ejects the slug.

When will the nACo Nano-Composite Blue coating need replacement, and what wears it out?

The coating extends tool life up to 30% over traditional HSS cutters; replace the cutter when cutting performance drops in steel, cast iron or stainless steel.
