Accupro 02703080 Back Chamfer 1/2 in 90 Deg Solid Carbide

Product Description

The ACCUPRO 02703080 is a solid carbide back chamfer tool designed for creating chamfered edges on the reverse side of drilled holes and bored features. Operating at a 90-degree included angle with a 1/2 inch cutter head diameter, it handles deburring and chamfering tasks where standard end-entry tools cannot reach. The right-hand cutting direction and bright/uncoated carbide construction make it well suited for use in ferrous and non-ferrous materials. With a 5/16 inch shank diameter and an overall length of 2.5 inches, it fits standard collet chucks and milling machine spindles used in production and job-shop environments. Machinists and CNC operators are the primary users.

This back chamfer tool is used in machining centers, knee mills, and drill presses for finishing through-holes and counterbored features where the chamfer must be applied from the underside. It is appropriate for single-piece and short-run production work in aerospace, automotive, and general metalworking applications. The single-end configuration keeps setup straightforward. Because carbide maintains edge integrity at higher speeds than high-speed steel, it supports consistent chamfer geometry over extended run cycles without frequent tool changes.

Key Features

• Solid carbide construction for edge retention and wear resistance in demanding materials
• 90-degree included angle produces consistent back chamfer geometry on through-holes
• 1/2 inch cutter head diameter for moderate to large hole chamfering applications
• 5/16 inch shank diameter compatible with standard collet and chuck systems
• Right-hand cutting direction for conventional CNC and manual mill spindle rotation
• Bright/uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement and standard-fitment back chamfer tool for use with 5/16 inch collet chucks and compatible toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists or CNC setup technicians following standard toolholding procedures. Power down the machine spindle and confirm it has come to a full stop before inserting or removing the tool from the collet. Verify shank engagement depth meets the toolholder manufacturer minimum before tightening. Do not exceed the toolholder or spindle speed rating for the selected cutter diameter.
