Accupro 12182622 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 12182622 is a solid carbide corner radius end mill designed for precision milling of metals and engineered materials. It carries a 5/8 inch diameter with a 0.0150 inch corner radius, a 4-flute spiral geometry, and a 40-degree helix angle for efficient chip evacuation and improved surface finish. The bright/uncoated finish suits general-purpose cutting where coating is not required. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. Machinists and CNC operators in job shops, production machining, and tool-and-die environments are the primary users of this tool.

This end mill is suited for use in CNC machining centers and manual mills performing slotting, profiling, and contouring operations. The corner radius geometry reduces stress concentration at the cutting edge compared to sharp-corner end mills, extending tool life in interrupted cuts and finishing passes. It is well-matched to ferrous and non-ferrous metals where a controlled edge radius is required on part geometry. The right-hand cutting and right-hand flute direction are standard for conventional milling setups.

Key Features

• 0.0150 inch corner radius with a tolerance of plus or minus 0.00150 inch for controlled edge geometry
• 4-flute spiral design with 40-degree helix angle for smooth chip flow and reduced cutting forces
• Solid micrograin carbide construction for rigidity and wear resistance
• Centercutting capability allows direct plunge entry without pre-drilling
• Single-end tool with 1-1/4 inch length of cut and 3-1/2 inch overall length
• Bright/uncoated finish suitable for general-purpose machining applications

Compatibility

Designed as a standard shank end mill with a 5/8 inch shank diameter, compatible with ER and other standard collet systems, side-lock holders, and shrink-fit toolholders sized for 5/8 inch shanks.

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 mounting or removing the tool. Seat the shank fully in the holder to the recommended gauge-line depth and torque the collet nut or set screw to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates corner radius wear.
