Accupro EM99943838 Chamfer Mill 1/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO EM99943838 is a single-end chamfer mill designed for chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous workpieces. Built from solid carbide, it delivers the rigidity and heat resistance needed for consistent performance in high-speed machining environments. The cutter head measures 0.125 inches in diameter with a 1/8 inch shank and an overall length of 1.5 inches. An AlTiN coating reduces friction and extends tool life when cutting hardened steels and other demanding materials. With 3 flutes and right-hand cutting direction, this mill suits CNC machining centers and manual mills where precise chamfer geometry is required.

This chamfer mill is suited for use in machine shops, toolrooms, and production environments handling light to medium material removal on metal components. The compact 1/8 inch diameter makes it appropriate for small-feature chamfering, tight-tolerance deburring, and countersink prep on workpieces where a larger tool would lack clearance. It is typically installed and operated by machinists and CNC programmers working on steel, stainless, cast iron, and similar materials. The 0.043 inch length of cut keeps the engagement zone controlled for fine edge work.

Key Features

• Solid carbide construction for rigidity and thermal stability in demanding cuts
• AlTiN coating reduces heat buildup and extends tool life on hardened materials
• 3-flute geometry balances chip evacuation with surface finish quality
• Right-hand cutting direction for standard spindle rotation compatibility
• Single-end design with 1/8 inch shank for use in standard collets and tool holders
• Compact 0.125 inch cutter head diameter for small-feature and tight-clearance applications

Compatibility

Designed as an OEM-style replacement chamfer mill for use in CNC machining centers and manual milling machines equipped with collet systems or tool holders accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a compatible collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout on a small-diameter carbide tool can cause premature breakage.
