Accupro 315027 Square End Mill 3/4 in 3 Flute Carbide

Product Description

The ACCUPRO 315027 is a solid carbide square end mill designed for precision milling operations across a range of materials. With a 3/4 inch cutting diameter, a 3-1/4 inch length of cut, and a 37-degree helix angle, this tool delivers efficient chip evacuation and stable cutting performance in deep-pocket and long-reach applications. The three-flute, right-hand spiral configuration balances chip load and surface finish, while micrograin carbide construction maintains edge integrity under demanding conditions. This is a single-end, centercutting tool, meaning it can plunge as well as contour cut. It ships in bright/uncoated finish, suitable for use in a variety of machining environments.

This end mill is suited for machining operations in job shops, tool rooms, and production environments where extended reach and a long length of cut are required. It handles slotting, profiling, and pocket milling in metals and engineered materials. The 3/4 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting. Its non-variable helix and no-chipbreaker design make it straightforward to apply in conventional CNC milling programs.

Key Features

• Solid micrograin carbide construction for superior edge retention and wear resistance
• 37-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Three right-hand flutes with right-hand cut for standard CNC mill spindle compatibility
• Bright/uncoated finish suitable for dry or wet cutting across multiple material types
• Mill diameter tolerance of +0.000 / -0.005 inches for consistent fit in close-tolerance work

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/4 inch collets, end mill holders, or shrink-fit toolholders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized collet or end mill holder before tightening. Verify runout with a dial indicator after clamping to protect edge life and part accuracy. Follow shop safety protocols and machine manufacturer guidelines for speeds, feeds, and coolant application.
