Accupro 95170012 Square End Mill 5/16 in 7 Flute Carbide

Product Description

The ACCUPRO 95170012 is a 7-flute solid carbide square end mill designed for high-performance material removal in demanding machining applications. Built from micrograin carbide and finished with an AlTiCrN coating, it delivers strong wear resistance and heat tolerance at elevated cutting speeds. The 5/16-inch diameter pairs with a 7/16-inch length of cut and a 38-degree helix angle, making it well suited for finishing passes and semi-finishing operations where surface quality and tool life are both priorities. Machinists and toolroom professionals are the primary users of this end mill.

This end mill is appropriate for use in CNC machining centers and manual mills handling ferrous and hardened materials where the AlTiCrN coating provides a meaningful performance advantage over standard TiN or TiAlN coatings. The right-hand cut and right-hand spiral flute geometry are standard for conventional and climb milling operations on vertical machining centers. The single-end design and 2-inch overall length make it a practical choice for close-tolerance work in confined pockets and slots where a shorter tool stack is an advantage. It belongs to the ACCUPRO HS series.

Key Features

• 7-flute geometry increases feed rate potential and improves surface finish compared to 4- or 5-flute designs
• AlTiCrN coating provides oxidation resistance and extended tool life in hard and abrasive materials
• 38-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Micrograin solid carbide substrate delivers rigidity and edge sharpness retention
• Right-hand cut with right-hand spiral for standard CNC and manual mill setups
• Single-end configuration with a 5/16-inch shank diameter for direct collet or end mill holder mounting

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual vertical mills accepting a 5/16-inch shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in a collet or end mill holder to the manufacturer-specified pull-out depth before tightening. Verify runout with a dial indicator after mounting and before initiating a cut. Follow shop safety protocols and machine guarding requirements when changing tooling.
