M.a. Ford 27925010B Ball End Mill 1/4 in 4 Flute Solid Carbide

Product Description

The M.A. FORD 27925010B is a solid carbide ball end mill designed for high-performance milling in demanding machining environments. Built to Series 279 standards, it features a 1/4 inch diameter with a 3/4 inch length of cut and a 2-1/2 inch overall length. The 4-flute geometry runs in a right-hand cutting and right-hand flute direction, while a variable helix design of 35 and 38 degrees reduces chatter and improves chip evacuation. The ALtima Blaze coating enhances wear resistance and heat dissipation, extending tool life in ferrous and non-ferrous materials alike. This single-end mill is sized for precision work on CNC machining centers and manual mills used in tool-and-die, mold, and general metalworking applications.

This end mill is suited for profiling, slotting, and contouring operations where a ball nose geometry is required to produce curved or blended surfaces. The 1/4 inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers. Its standard length profile keeps it rigid in setups with moderate reach requirements. Machinists working in job shops, aerospace component shops, and precision manufacturing facilities will find this tool appropriate for finishing passes on hardened steels, stainless, and alloy materials where tool life and surface finish matter.

Key Features

• 1/4 inch ball nose diameter with 0.125 inch nose radius for smooth contoured surface generation
• Variable helix at 35 and 38 degrees reduces harmonic vibration and improves chip flow
• Variable index geometry distributes cutting forces more evenly across flutes
• ALtima Blaze coating provides high heat resistance and extended wear life in ferrous alloys
• Solid carbide construction delivers rigidity and dimensional stability at elevated cutting speeds
• Single-end, 4-flute spiral flute design optimized for finishing and semi-finishing passes

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling setups accepting a 1/4 inch shank diameter. Compatible with ER collet systems and precision end mill holders of appropriate bore size.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a torque wrench and manufacturer-specified collet nut procedure when seating the shank in an ER chuck to prevent pullout during cutting. Inspect the cutting edges and coating condition before each use; do not run a chipped or damaged carbide tool.
