Harvey Tool 65810 Back Chamfer Tool 0.115in 90deg 5 Flute

Product Description

The HARVEY TOOL 65810 is a solid carbide back chamfer tool designed to create precise chamfers on the reverse side of bored or drilled holes. With a 0.115 inch cutter head diameter, a 90-degree included angle, and a 0.011 inch chamfer width, this tool delivers controlled material removal in tight back-chamfering applications. The five-flute geometry provides a smooth cutting action and improved chip evacuation compared to lower flute-count alternatives. The bright, uncoated finish suits general-purpose machining on a wide range of workpiece materials. This tool is typically installed and operated by CNC machinists and tool-and-die professionals working on precision components.

The HARVEY TOOL 65810 is suited for back chamfering operations on machined parts where access from the front face is not possible. Common applications include deburring and chamfering the back edges of cross-drilled holes, counterbores, and through-holes in ferrous and non-ferrous components. The 1/8 inch shank diameter and 0.087 inch neck diameter allow the tool to reach into confined geometries. The 2 inch overall length provides sufficient reach for most standard back-chamfer operations encountered in production and job-shop environments.

Key Features

• 0.115 inch cutter head diameter for precise back-chamfer sizing
• 90-degree included angle produces a standard chamfer profile
• 0.011 inch chamfer width for controlled, repeatable edge breaks
• Five-flute solid carbide construction for rigidity and extended tool life
• 0.087 inch neck diameter enables access into tight bore geometries
• Bright, uncoated finish suitable for general-purpose machining applications

Compatibility

Designed as a back chamfer tool for use in CNC machining centers and manual mills accepting a 1/8 inch shank diameter collet or toolholder.

Installation Notes

Installation is performed by machinists using a collet or toolholder rated for 1/8 inch shank tooling. Confirm runout and shank seating before operation, as solid carbide is brittle and sensitive to deflection. Set spindle speeds and feed rates according to the workpiece material and consult the manufacturer cutting data tables before first use. Never exceed the tool diameter when programming radial engagement for back-chamfer passes.
