Accupro 312930 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 312930 is a 2-flute solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide stock, it delivers a rigid cutting edge that holds tight tolerances on ferrous and non-ferrous materials. The 1/8 inch cutting diameter pairs with a 45-degree right-hand helix angle for efficient chip evacuation and reduced cutting forces. With a bright, uncoated finish and centercutting capability, this tool handles slotting, profiling, and plunge operations without additional prep. Machinists and CNC operators installing this tool will find it suited to close-tolerance work where a long-reach, small-diameter carbide tool is required.

This end mill is appropriate for production and job-shop environments running CNC mills, manual vertical mills, or machining centers. The long length type and 5/8 inch length of cut give additional reach into deep pockets or stepped features while maintaining the rigidity of solid carbide construction. The 1/8 inch shank diameter matches the cutting diameter for direct collet or ER-style chuck mounting, making it a straightforward fit in standard 1/8 inch toolholders.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• 45-degree right-hand helix promotes efficient chip evacuation and smooth cut finish
• Centercutting design enables direct plunge entry without pre-drilling
• Bright, uncoated finish suitable for a wide range of work materials without coating compatibility concerns
• Long length type with 5/8 inch length of cut for added reach in deep pockets
• Tight diameter tolerances: +0.000 / -0.002 inches on mill diameter, +0.0001 / -0.0004 inches on shank

Compatibility

Designed for use in standard 1/8 inch collets, ER-style chucks, and precision toolholders on CNC machining centers and manual vertical mills requiring a small-diameter, long-reach solid carbide square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Insert the shank to the full recommended grip depth in the collet or toolholder, and verify runout with a dial indicator before beginning a cut. Follow the machine manufacturer and tooling supplier feeds-and-speeds guidelines for solid carbide small-diameter end mills to avoid tool breakage.
