Accupro 95169969 Square End Mill 3/8 in 7 Flute Solid Carbide

Product Description

The ACCUPRO 95169969 is a 7-flute solid carbide square end mill designed for high-performance milling in demanding machining environments. It measures 3/8 inches in diameter with a 7/8-inch length of cut and a 2-1/2-inch overall length. The AlTiCrN coating provides superior heat and wear resistance, making it well suited for hard-material cutting applications. The 38-degree helix angle promotes smooth chip evacuation and stable cutting action. Micrograin carbide construction delivers edge retention and rigidity across a range of workpiece materials. This tool is installed and used by machinists and tooling professionals on CNC mills and manual knee mills.

This end mill is applicable to milling operations requiring a high flute count for improved surface finish and feed rates in finishing and semi-finishing passes. It is a single-end, right-hand cut tool with right-hand flute direction. The 3/8-inch shank diameter fits standard collets and end mill holders. Its Series HS designation indicates a high-performance geometry optimized for harder workpiece materials. Typical applications include peripheral milling, slotting, and profiling in ferrous and hardened materials where coating-assisted heat management is critical.

Key Features

• 7-flute geometry supports higher feed rates and improved surface finish in finishing operations
• AlTiCrN coating enhances wear resistance and performance in high-heat cutting conditions
• 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Micrograin solid carbide substrate provides rigidity and edge retention
• Right-hand cut and right-hand flute spiral for standard CNC and manual mill setups
• Single-end design; not centercutting — not intended for direct plunge operations

Compatibility

Designed as a replacement-style solid carbide square end mill for use in standard 3/8-inch collets, end mill holders, and shrink-fit holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet or holder runout is within acceptable tolerance before tightening, as excessive runout reduces tool life and surface finish quality. Do not use this tool for direct plunge cutting, as it is a non-centercutting design.
