Accupro 313033 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313033 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering material applications. With a 1/4 inch cutting diameter, a 5/8 inch length of cut, and a 45-degree helix angle, this tool delivers efficient chip evacuation and clean edge geometry in a compact, single-end configuration. The micrograin carbide construction provides hardness and edge retention beyond high-speed steel tooling. Machining professionals and toolroom operators use this end mill for slotting, profiling, and contouring operations where dimensional accuracy and surface finish are critical.

This end mill is suited for CNC machining centers and manual knee mills in production and toolroom environments. The right-hand cutting direction and right-hand spiral flute geometry make it compatible with conventional spindle setups. The bright uncoated finish makes it appropriate for use in non-ferrous metals, aluminum, brass, and plastics where coated tooling may not be preferred. The 1/4 inch shank diameter fits standard 1/4 inch collets and end mill holders.

Key Features

• Solid micrograin carbide construction for superior edge retention and wear resistance
• 45-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• Center-cutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Bright uncoated finish suited for non-ferrous and non-abrasive material applications
• 2-flute geometry maximizes chip clearance in slotting and full-width cuts

Compatibility

Designed as a standard replacement or stock end mill for use in 1/4 inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Insert the shank fully into the collet or holder to the recommended engagement depth and torque the retention nut to the tool holder specification. Verify runout with a dial indicator before beginning cuts, as excessive runout will accelerate edge wear and reduce dimensional accuracy.
