Accupro 12277220 Ball End Mill 0.0950in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12277220 is a miniature solid carbide ball end mill designed for precision milling operations in tight tolerances and small-feature work. It measures 0.0950 inches in diameter with a 0.1420-inch length of cut and a 1.5-inch overall length. The 4-flute, single-end design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Constructed from micrograin solid carbide, this end mill delivers rigidity and wear resistance suited to close-tolerance work in ferrous and non-ferrous materials. The bright/uncoated finish makes it suitable for a broad range of machining applications without added coating considerations.

This end mill is intended for CNC machining centers and manual milling machines where small-diameter tooling is required. Its miniature series classification makes it well suited to engraving, slotting, contouring, and profiling operations on small components. The 1/8-inch shank diameter fits standard collet systems commonly found in vertical machining centers and die and mold shops. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups.

Key Features

• 0.0950-inch mill diameter with a tight tolerance of +0.0000 / -0.0010 inches for precise feature control
• 4-flute spiral design with 30-degree helix angle for smooth chip flow and surface finish
• Micrograin solid carbide construction for hardness and edge retention in demanding cuts
• Single-end, right-hand cut with right-hand flute direction for standard milling setups
• Bright/uncoated finish compatible with a wide range of workpiece materials
• 1/8-inch shank diameter fits common collet and toolholder systems

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills equipped with 1/8-inch collet or toolholder systems requiring miniature ball end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout verification procedures. Ensure the milling machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth and collet condition before securing. Follow applicable shop safety standards and machine manufacturer guidelines for small-diameter carbide tooling.
