Accupro 95168872 Ball End Mill 1 in 4 Flute Altin Solid Carbide

Product Description

The ACCUPRO 95168872 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 1 inch cutting diameter and a 2 inch length of cut, this tool handles deep-cavity profiling, contouring, and finishing passes on hardened and abrasion-resistant materials. The AlTiN (aluminum titanium nitride) coating extends tool life by increasing surface hardness and thermal resistance at the cutting edge. A 4-flute, right-hand spiral geometry paired with a variable helix design reduces chatter and improves chip evacuation. The C2 material grade solid carbide substrate delivers the rigidity needed for demanding ferrous and non-ferrous machining.

This end mill is suited for use on CNC machining centers and manual mills where a single-end ball profile is required. Common applications include die and mold work, 3D contour milling, and finishing operations in steel, stainless steel, cast iron, and hardened alloys. The 4 inch overall length with a 1 inch shank diameter provides the reach and stability needed for moderate-depth cavity work. It is typically selected by machinists and tool-and-die professionals working in job shops, aerospace component manufacturing, and precision mold making environments.

Key Features

• AlTiN coating increases hardness and thermal resistance for extended tool life in ferrous materials
• Variable helix flute geometry reduces vibration and chatter during contouring cuts
• 4-flute right-hand spiral design improves chip flow and surface finish
• Solid carbide C2 grade substrate for rigidity and wear resistance
• Single-end ball profile suited for 3D profiling, die work, and radius finishing
• Mill diameter tolerance of +0.000 / -0.002 inches ensures accurate dimensional control

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard CNC and manual milling machine spindles accepting a 1 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Use an appropriate end mill holder or collet rated for a 1 inch shank diameter and torque to the tool holder manufacturer specifications. Confirm spindle RPM and feed rate are set per material and coating recommendations before initiating a cut.
