Fein 63134143041 Annular Cutter 9/16 in Hss Bright

Product Description

The FEIN 63134143041 is a high speed steel (HSS) annular cutter designed for clean, fast through-holes in steel and ferrous materials. Built from M2 grade HSS with a bright, uncoated finish, this cutter features a 9/16 inch cutting diameter and a 1 inch depth of cut. The 3/4 inch shank diameter seats securely in compatible magnetic drill presses and annular cutter chucks. Annular cutters remove only a core slug rather than a full disc of material, which reduces heat buildup, extends tool life, and produces accurate holes with minimal burring. Metal fabricators, structural ironworkers, and mechanical contractors reach for this type of cutter when speed and hole quality matter on structural steel or plate work.

This cutter is suited for use in magnetic drill press applications on structural steel, plate, tube, and pipe. The 1 inch depth of cut accommodates most standard plate and structural member thicknesses encountered in fabrication and field work. The 3/4 inch shank is a widely adopted standard in industrial mag-drill chucks, making this cutter compatible across a broad range of mag-drill platforms. It is a single-piece cutter packaged individually, appropriate for professional shop and jobsite use.

Key Features

• 9/16 inch cutting diameter for precision through-hole drilling in ferrous materials
• 1 inch depth of cut handles standard structural plate and tube thicknesses
• M2 grade high speed steel construction for heat resistance and edge retention
• 3/4 inch shank diameter fits standard industrial mag-drill and annular cutter chucks
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Annular cutting geometry removes a core slug, reducing cutting force and heat compared to twist drills

Compatibility

Designed for use with magnetic drill presses and annular cutter holders that accept a 3/4 inch shank. Verify chuck arbor compatibility before installation.

Installation Notes

Annular cutters are installed and serviced by metal fabricators, ironworkers, and mechanical tradespeople. Before changing cutters, de-energize the magnetic drill and allow any rotating tooling to come to a full stop. A pilot pin is typically required to center the cutter and retain the slug during the cut — confirm the correct pilot pin length for the depth of cut. Apply cutting oil to the workpiece during use to extend cutter life and reduce heat.
