Accupro 02703056 Back Chamfer Tool 0.49in 90 Degree Carbide

Product Description

The ACCUPRO 02703056 is a solid carbide back chamfer tool designed for deburring and chamfering the reverse side of holes and bores in precision machining applications. With a 0.49-inch cutter head diameter and a 90-degree included angle, it produces a 0.07-inch chamfer width in a single pass. The bright, uncoated solid carbide construction provides excellent hardness and edge retention across a wide range of materials. This is a single-end tool with a right-hand cutting direction, suited for use in CNC machining centers and manual mills where back-chamfering is required without repositioning the workpiece.

This back chamfer tool is used in metalworking and precision machining environments, including aerospace, automotive, and general manufacturing shops. It is designed to access the underside of through-holes and counterbores, eliminating the need to flip a part for chamfer finishing. The 3-inch overall length and 0.35-inch neck diameter allow clearance in standard bore depths. A licensed machinist or CNC operator typically selects this tool for finishing operations on ferrous and non-ferrous metals, as well as some plastics.

Key Features

• 0.49-inch cutter head diameter with a 90-degree included angle for consistent back chamfering
• 0.07-inch chamfer width and 0.031-inch flat width per pass
• Solid carbide construction for hardness and long edge life
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Right-hand cutting direction for standard spindle rotation
• 1-inch cutter head to shank length for clearance in typical bore applications

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 0.5-inch shank diameter. Verify spindle collet or chuck capacity before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the collet or chuck. Ensure the shank is fully seated and the collet is torqued to the machine manufacturer's specification. Do not use this tool for forward chamfering applications where a standard chamfer mill is the appropriate choice.
