Accupro 95168253 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 95168253 is a solid carbide square end mill designed for high-performance milling in demanding cutting applications. With a 3/16 inch (0.1875 inch) mill diameter and a 5/8 inch (0.625 inch) length of cut, this tool is built for precise material removal in tight geometries. The AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. A variable helix flute geometry reduces chatter and harmonics during cuts, which improves surface finish and dimensional accuracy. Machinists and toolroom professionals working in CNC milling centers are the primary users of this tool.

This end mill is suited for slotting, profiling, and peripheral milling operations on ferrous metals, stainless steel, and high-temperature alloys where coating performance and edge retention are critical. The 4-flute, right-hand cutting configuration and right-hand spiral flute direction make it appropriate for conventional and climb milling passes. The regular length classification and 2 inch overall length keep it rigid enough for accurate work at this diameter. It is a single-end, center-cutting tool, so it can be used for plunge entry as well as lateral cutting passes.

Key Features

• AlTiN coating for high heat resistance and extended tool life in ferrous and hardened materials
• Variable helix geometry reduces vibration and chatter for improved surface finish
• 4-flute, right-hand cut and right-hand spiral for efficient chip evacuation
• Micrograin solid carbide construction provides rigidity and edge retention
• Center-cutting capable, allowing direct plunge entry without a pre-drilled hole
• Mill diameter tolerance of +0.000 / -0.002 inch for consistent fit and runout control

Compatibility

Designed as a standard shank end mill compatible with 3/16 inch ER collets, end mill holders, and milling chucks used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the collet or holder to minimize runout and prevent pull-out. Verify collet and holder cleanliness before seating the tool, as contamination directly affects runout and tool life.
