Htc 150-4750 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The HTC 150-4750 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineered materials. With a 3/4 inch mill diameter and a 2-1/4 inch length of cut, this tool handles deep slotting, profiling, and peripheral milling where rigidity and edge retention are critical. The 4-flute helical geometry promotes efficient chip evacuation while maintaining surface finish quality. At 5 inches overall length, it falls into the long series category, giving technicians additional reach for deeper workpiece features without sacrificing tool body stiffness.

This end mill suits general-purpose CNC and manual milling applications in job shops, production facilities, and maintenance environments. The bright uncoated finish makes it appropriate for a wide range of ferrous and non-ferrous materials where coating interaction is a concern. Right-hand cutting and right-hand flute direction follow standard milling conventions. The square shank seats directly into standard 3/4 inch collets or end mill holders without additional adapters.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS tooling
• 3/4 inch mill diameter with matching 3/4 inch square shank for direct holder fitment
• 2-1/4 inch length of cut accommodates deeper axial passes and stepped features
• 4-flute helical design balances chip load, finish quality, and feed rate capability
• Bright uncoated finish suitable for applications where coating is not required or desired
• Right-hand cut, right-hand helix - standard orientation for conventional milling setups
• Long series overall length of 5 inches for extended reach applications

Compatibility

Designed for use with standard 3/4 inch end mill holders, collet chucks, and milling arbors on CNC machining centers and manual knee mills accepting straight square shanks.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into the holder to the recommended minimum engagement depth and torque set screws per the holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates carbide edge chipping.
