Accupro EM99943867 Chamfer Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO EM99943867 is a single-end chamfer mill designed for creating chamfers, bevels, and deburring edges on metal workpieces. Built from solid carbide, this cutter delivers the rigidity and wear resistance needed for consistent performance in ferrous and non-ferrous materials. The AlTiN coating reduces heat buildup and extends tool life in dry or semi-dry cutting conditions. With a 1/2 inch cutter head diameter, 4 flutes, and a right-hand cutting direction, it suits a range of chamfering and countersinking operations on CNC machining centers and manual mills alike. Machinists and tool-and-die professionals are the primary users.

This chamfer mill is suited for production and job-shop environments where precision edge preparation is required. Typical applications include chamfering drilled holes, prepping weld joints, and countersinking fastener seats in steel, stainless steel, aluminum, and similar materials. The solid carbide construction and AlTiN finish make it particularly effective in moderate-to-high-speed cutting conditions where heat and tool wear are primary concerns. The 1/2 inch shank diameter fits standard collet chucks and end mill holders common to most CNC and manual milling setups.

Key Features

• Solid carbide construction provides rigidity and extended tool life compared to HSS alternatives
• AlTiN coating improves heat resistance and reduces friction in high-speed cuts
• 4-flute geometry balances chip evacuation and surface finish quality
• Right-hand cutting direction compatible with standard spindle rotation
• Single-end design with 0.513 inch length of cut for precise chamfer depth control
• No coolant-through requirement simplifies setup on machines without internal coolant

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 1/2 inch collet chucks, end mill holders, and shrink-fit holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or tool-setup personnel. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully in the holder and torque set screws or collet nuts according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts.
