Accupro 02703072 Back Chamfer 3/8 in 90 Degree Carbide

Product Description

The ACCUPRO 02703072 is a solid carbide back chamfer tool designed to create clean, precise chamfers on the reverse side of drilled or bored holes. Constructed entirely from carbide, it delivers the hardness and wear resistance required for consistent performance in production machining environments. The tool operates at a 90-degree included angle and features a 1/32-inch flat width at the cutting edge. With an overall length of 2.5 inches and a 1/4-inch shank diameter, it is sized for use in standard collet chucks and tool holders found on CNC machining centers and manual mills. A bright finish is applied to the flute surfaces. Machinists and tool-and-die technicians rely on this style of tool for deburring and chamfering operations that cannot be reached from the entry side of a workpiece.

This back chamfer tool is suited for use on ferrous and non-ferrous workpieces where back-side chamfering or deburring is required after drilling, reaming, or boring. It is commonly used in precision component machining, aerospace part production, and general metalworking shops. The single-end configuration makes it straightforward to set up in standard tool holders. It is appropriate for use on CNC machining centers, knee mills, and drill presses equipped with collet systems that accept a 1/4-inch shank.

Key Features

• Solid carbide construction for hardness and extended tool life
• 90-degree included angle for standard back chamfering
• 1/32-inch flat width at the cutting edge for controlled chamfer geometry
• 1/4-inch shank diameter fits standard collet and tool holder systems
• 2.5-inch overall length provides reach into blind-side applications
• Bright finish on flute surfaces

Compatibility

Designed as an OEM-style back chamfer tool for use with standard 1/4-inch collet chucks and tool holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. The machine spindle must be fully stopped and the control placed in a safe state before changing tooling. Verify that the 1/4-inch shank is fully seated and properly torqued in the collet or tool holder per the machine manufacturer's specifications. Confirm workpiece fixturing is secure before initiating a back chamfering operation, as the cutting forces act in the reverse axial direction relative to standard end milling.
