Accupro 315105 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 315105 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1 inch cutting diameter and a 5.5 inch length of cut, making it well suited for deep-cavity and long-reach milling applications. The three-flute configuration paired with a 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating increases surface hardness and thermal resistance, extending tool life in demanding cutting environments. This end mill is center-cutting and runs in a right-hand cutting and flute direction, compatible with standard vertical and horizontal CNC machining centers.

This end mill is intended for use in professional machining operations where deep reach and rigidity are required. The 8 inch overall length and 1 inch shank diameter make it appropriate for setups requiring extended tool projection on CNC mills and machining centers. Micrograin carbide construction supports tight tolerances and consistent performance across production runs. It is a single-end tool, standard in industrial toolrooms, job shops, and production machining environments where solid carbide tooling is specified for accuracy and repeatability.

Key Features

• 1 inch cutting diameter with mill diameter tolerance of +0.000 / -0.005 inches
• 5.5 inch length of cut for deep-cavity and long-reach applications
• 3-flute spiral flute geometry with 37-degree helix for efficient chip removal
• ZrN (zirconium nitride) coating for increased hardness and heat resistance
• Micrograin solid carbide construction for wear resistance and dimensional stability
• Center-cutting, right-hand cut and flute, single-end design
• 1 inch shank diameter with tolerance of +0.0001 / -0.0004 inches

Compatibility

Designed as a direct-fit solid carbide end mill for CNC machining centers and manual mills accepting a 1 inch straight shank. Suitable for applications specifying a length-of-cut range at or above 2 inches.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank in a collet, end mill holder, or shrink-fit toolholder rated for the 1 inch shank diameter and confirm runout before cutting. Power down the machine and lock out energy sources before changing tooling. Do not exceed the tool's rated depth of cut or feed rate as specified in the machining program for the material being cut.
