Accupro 12177421 Square End Mill 1/2 in 6 Flute Solid Carbide

Product Description

The ACCUPRO 12177421 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. The 6-flute configuration with a 45-degree helix angle supports aggressive material removal while maintaining a fine surface finish. At 0.5 inches in diameter with a 0.625-inch length of cut, this end mill handles slotting, profiling, and contouring tasks where tight tolerances are required. It is an uncoated, single-end tool with right-hand cut and right-hand spiral flute geometry, centercutting-capable for plunge entry.

This end mill is suited for CNC machining centers and manual mills used in job shops, tool rooms, and production environments. The 0.5-inch shank diameter fits standard ER and end mill holders common to most vertical machining centers. The 2.5-inch overall length keeps the tool rigid and reduces deflection in typical short-reach milling setups. Machinists running finish passes on steel, aluminum, or similar materials will find the 6-flute geometry well-matched to higher feed rates at moderate depths of cut.

Key Features

• Micrograin solid carbide construction for edge retention and wear resistance
• 6-flute design supports higher feed rates and improved surface finish
• 45-degree helix angle reduces cutting forces and improves chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand spiral flute configuration
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment

Compatibility

Designed for use in standard 0.5-inch end mill holders or collet chucks on CNC vertical machining centers and manual knee mills requiring a 6-flute square end mill with a 0.5-inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Secure the shank to the proper torque specification for your tool holder type per the holder manufacturer guidelines. Verify runout with a dial indicator after installation before beginning a cut, as excessive runout will accelerate edge wear and reduce dimensional accuracy.
