Accupro 315086 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 315086 is a single-end, solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length. The three-flute, right-hand spiral geometry runs at a 37-degree helix angle, promoting efficient chip evacuation and reduced cutting forces. A zirconium nitride (ZrN) coating improves surface hardness and heat resistance, extending tool life in demanding cutting conditions. The micrograin carbide substrate provides the rigidity and edge retention required for consistent dimensional accuracy across production runs.

This end mill is suited for milling operations in job shops, tool rooms, and production machining environments. It is a center-cutting tool, allowing direct plunge entry as well as conventional side milling and slotting. The 1 inch shank diameter accommodates standard end mill holders and collet chucks. It is appropriate for use on CNC machining centers and manual knee mills where a 1 inch tool is specified. The right-hand cutting direction is compatible with standard spindle rotation on most vertical and horizontal machining platforms.

Key Features

• 1 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.005 inches for consistent fitment
• 3 inch length of cut supports deep-pocket and full-depth side milling applications
• 3-flute, right-hand spiral geometry at 37-degree helix for efficient chip flow
• ZrN coating increases surface hardness and thermal resistance for extended tool life
• Micrograin solid carbide construction delivers rigidity and sharp edge retention
• Center-cutting design allows direct plunge milling without a pre-drilled pilot hole

Compatibility

Designed for use in standard 1 inch end mill holders and collet chucks on CNC machining centers and manual mills requiring a 1 inch shank, single-end square end mill.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding standards and safe tooling practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Seat the shank to the recommended engagement depth specified by the tool holder manufacturer and torque set screws or collet nuts per the holder manufacturer guidelines. Inspect the cutting edges and coating for damage before each use and replace the tool if chipping or excessive wear is observed.
