Accupro 12179757 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12179757 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.75 inch mill diameter, a 1.625 inch length of cut, and a 4 inch overall length, this tool is built for reliable material removal in ferrous and non-ferrous metals. The micrograin carbide substrate and AlTiN coating provide heat and wear resistance at elevated cutting speeds. Three spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. It is a centercutting design, allowing plunge entry, and runs right-hand cut with right-hand flute geometry.

This end mill suits vertical and horizontal machining centers in job shop and production environments. The regular length configuration and 0.75 inch shank diameter make it straightforward to chuck in standard collets or end mill holders. It is appropriate for slotting, profiling, and peripheral milling operations where tight tolerances and tool life are priorities. Licensed machinists and CNC operators working in aerospace, mold and die, and general precision machining will find this geometry well suited to demanding cutting conditions.

Key Features

• Solid carbide micrograin substrate for rigidity and edge retention
• AlTiN finish for thermal resistance and extended tool life in dry or semi-dry cutting
• 40-degree helix spiral flute for efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute geometry for standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 0.75 inch shank diameter via collet chuck or end mill holder. Suitable for cutting ferrous metals, alloy steels, and similar materials where AlTiN coating performance is appropriate.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Secure the shank to the full recommended engagement depth in the holder and verify runout with a dial indicator before cutting. Follow applicable shop safety standards and machine-specific tooling torque procedures as specified by the holder manufacturer.
