Accupro 313592 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313592 is a single-end ball end mill designed for precision contouring, profiling, and 3D machining operations on CNC machining centers and manual mills. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for cutting ferrous and non-ferrous materials. The 1/4 inch diameter cutting edge pairs with a 45-degree right-hand spiral helix to promote efficient chip evacuation and reduced cutting forces. The bright, uncoated finish makes it well suited for applications where coating compatibility or cost is a factor. Machinists and tool-and-die professionals rely on this geometry for finishing passes and detail work in dies, molds, and contoured components.

This end mill fits standard 1/4 inch collets and tool holders common to vertical machining centers and CNC routers. The 3/4 inch length of cut accommodates moderate-depth profiling and slotting in a range of workpiece materials. With a 2-1/2 inch overall length and a 1/4 inch shank, it is suited for close-tolerance work in production and job-shop environments. The right-hand cutting direction follows standard CNC spindle rotation, making setup straightforward for most machining applications.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• Ball end geometry enables contouring, 3D profiling, and radial cuts
• 45-degree helix angle promotes smooth chip flow and reduced chatter
• 2-flute configuration provides efficient chip clearance in moderate-feed operations
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Mill diameter tolerance of plus 0.000 inches and minus 0.002 inches for close-tolerance fitment

Compatibility

Designed for use in standard 1/4 inch collet chucks and end mill holders on CNC machining centers, vertical mills, and compatible CNC routers requiring a single-end ball end mill with right-hand cut and right-hand flute direction.

Installation Notes

Installation is performed by a machinist or toolroom professional. Power down and lock out the spindle before loading or removing any end mill. Seat the shank fully in a clean, undamaged collet or tool holder and torque the retention nut to the tool holder specification. Inspect the cutting edges for chips or damage before each use, and confirm runout with a dial indicator when tight tolerances are required.
