Accupro E599943865 Chamfer Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO E599943865 is a solid carbide chamfer mill designed for precision chamfering, deburring, and edge-breaking operations on metal and composite workpieces. The cutter head measures 0.250 inches in diameter with a matching 1/4 inch shank, and the tool runs 2.5 inches overall length. Three flutes and a right-hand cutting direction deliver clean, consistent chip evacuation at typical chamfering feeds and speeds. The bright, uncoated finish suits general-purpose applications where coating chemistry is a concern or where re-sharpening is anticipated. This tool is handled by machinists and CNC setup technicians in production and job-shop environments.

This chamfer mill is suited for use in CNC machining centers and manual mills where chamfering, spot-facing, or countersinking operations are required. The single-end design is standard for toolholder collet setups using 1/4 inch ER or similar collet systems. The 0.229 inch length of cut accommodates light chamfer passes on steel, aluminum, cast iron, and engineering plastics. It is a practical choice for shops that need a compact, reliable carbide chamfer tool without a specialty coating.

Key Features

• Solid carbide construction provides rigidity and wear resistance at elevated cutting speeds
• 3-flute geometry balances chip clearance with surface finish quality
• Right-hand cutting direction for standard spindle rotation
• Bright, uncoated finish allows direct use on aluminum and non-ferrous materials without built-up edge concerns
• Single-end design simplifies toolholder setup in collet chucks
• No coolant-through requirement reduces toolholder complexity

Compatibility

Designed as an OEM-style solid carbide chamfer mill compatible with 1/4 inch collet toolholders in standard CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC technician. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the collet. Use a calibrated torque wrench on the collet nut per the toolholder manufacturer's specification. Confirm runout with a dial indicator before production cutting to avoid premature tool wear or poor chamfer geometry.
