Accupro 12182286 Square End Mill 7/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12182286 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. It features a 7/16 inch (0.4375 inch) mill diameter, a 1 inch length of cut, and a 4 inch overall length. The three-flute, spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this end mill delivers the rigidity and wear resistance required for demanding cutting conditions. It is an uncoated, single-end tool with right-hand cut and right-hand flute orientation, and it is centercutting, allowing plunge entry into the workpiece.

This end mill is suited for use in CNC machining centers and manual milling machines across job shops, production floors, and toolrooms. Its long-length designation and 1 inch length of cut make it appropriate for reaching into slots, pockets, and features that shorter tools cannot access. Typical materials include ferrous and non-ferrous metals where a micrograin carbide substrate provides the edge stability needed to maintain tolerance and surface finish throughout the cut.

Key Features

• Solid micrograin carbide construction for rigidity and extended edge life
• 40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Three-flute spiral configuration balances material removal rate with tool strength
• Right-hand cut and right-hand flute orientation for standard spindle compatibility
• Uncoated finish suitable for use with appropriate cutting fluids on a range of materials

Compatibility

Designed as a standard shank end mill for use in collet chucks, end mill holders, and shrink-fit toolholders accepting a 7/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended insertion depth in the toolholder and verify runout with a dial indicator before beginning the cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut based on workpiece material.
