Accupro 12177410 Square End Mill 5/16 in 6 Flute Carbide

Product Description

The ACCUPRO 12177410 is a solid carbide square end mill engineered for high-performance milling in ferrous and non-ferrous materials. It measures 5/16 inch in diameter with a 13/16 inch length of cut and a 2-1/2 inch overall length. The 6-flute geometry paired with a 45-degree helix angle promotes aggressive material removal while maintaining a smooth surface finish. An AlTiN coating adds heat and wear resistance, extending tool life in dry or semi-dry cutting conditions. The micrograin carbide substrate provides the rigidity and edge retention needed for tight-tolerance work. Licensed machinists and toolroom operators are the primary users of this end mill.

This end mill is suited for peripheral and slot milling operations in machine shops, tool-and-die environments, and production machining cells. The centercutting design allows plunge entry directly into the workpiece, making it versatile for pocketing and ramping passes. Right-hand cut and right-hand flute orientation are standard for conventional CNC machining center setups. The spiral flute design promotes efficient chip evacuation, reducing the risk of recutting chips during deep-pocket operations.

Key Features

• 6-flute solid carbide construction for high feed rates and fine surface finish
• 45-degree helix angle reduces cutting forces and improves chip flow
• AlTiN coating for elevated heat resistance in ferrous and hardened material applications
• Centercutting capability allows direct plunge milling without pre-drilling
• Micrograin carbide substrate maintains edge integrity under high cutting loads
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a standard shank end mill for use in CNC machining centers, knee mills, and other rotating spindle equipment accepting a 5/16 inch straight shank tool holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an E-stop or locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended gauge line and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before starting a production cut.
