Accupro 32497851 Ball End Mill 5/32 in 4 Flute Carbide

Product Description

The ACCUPRO 32497851 is a single-end ball end mill designed for precision milling of contoured surfaces, pockets, and slots. Built from solid carbide and coated with AlTiCrN, this tool offers strong heat and wear resistance in demanding cutting applications. It runs a 5/32 inch (0.1562 inch decimal) cutting diameter with a 0.1450 inch length of cut and a 3/16 inch shank diameter. The four-flute geometry with variable index provides improved surface finish and reduced chatter compared to evenly spaced flute layouts. Machinists and tool-and-die professionals reach for this size in close-tolerance finishing work.

This end mill is suited for milling operations on hardened steels, stainless steels, and high-temp alloys where AlTiCrN coating performance is an advantage. The compact 0.1450 inch length of cut and 0.2500 inch neck length make it appropriate for controlled-depth profiling and semi-finish passes in CNC machining centers. The 2 inch overall length fits standard ER and collet-style toolholders commonly used in vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• AlTiCrN coating provides excellent oxidation resistance and thermal stability at elevated cutting temperatures
• Variable index flute spacing reduces harmonic vibration and improves surface finish
• Four-flute design increases material removal rate relative to two- or three-flute alternatives
• Single-end configuration with 3/16 inch shank for use in standard collet toolholders
• 0.2500 inch neck length supports reach into shallow pockets without excessive overhang

Compatibility

Designed as an OEM-style replacement and standard cutting tool for CNC machining centers accepting a 3/16 inch shank diameter in ER, collet chuck, or equivalent toolholding systems.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and locked out per shop lockout/tagout procedures. Seat the shank fully into the toolholder and torque the collet nut to the toolholder manufacturer's specification using the appropriate spanner wrenches. Inspect the cutting edges and coating for chips or damage before mounting. Verify runout with a dial indicator before initiating a cutting pass.
