Accupro 12181677 Square End Mill 7/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181677 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. The cutter measures 7/16 inches in diameter with a 5/8-inch length of cut and a 2-inch overall length. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding cuts in ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a stub-length, single-end tool with an uncoated finish, suited for standard general-purpose milling work performed by machinists and tool-and-die professionals.

This end mill is sized for use in CNC machining centers, manual knee mills, and similar equipment where a 7/16-inch shank diameter is the specified toolholder size. The stub length configuration provides added rigidity in shallow-pocket and slotting operations where deflection must be minimized. It is appropriate for use in job shops, production environments, and toolroom applications requiring consistent dimensional accuracy. The right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Stub-length configuration increases rigidity and reduces deflection in shallow cuts
• Right-hand cut and right-hand spiral flute for standard milling setups
• Diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a direct-fit replacement or new-install square end mill for any toolholder or collet accepting a 7/16-inch shank diameter in CNC or manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool is seated to the correct gauge-line depth before tightening the collet or end mill holder. Verify runout with a dial indicator after installation and before cutting. Do not exceed the recommended depth-of-cut for the material being machined.
