Hertel 750146 Square End Mill 7/64 in 2 Flute Solid Carbide

Product Description

The HERTEL 750146 is a solid carbide square end mill designed for precision milling in metal, composites, and engineering plastics. With a 7/64 inch (0.1094 inch) cutting diameter and a 3/8 inch length of cut, this tool delivers clean, square-shouldered profiles in tight-tolerance applications. The 2-flute, 30-degree spiral flute geometry promotes efficient chip evacuation and reduces cutting forces in slotting and peripheral milling operations. The 1/8 inch shank diameter and 1-1/2 inch overall length make it well-suited for small-feature work in CNC machining centers and manual mills. The uncoated carbide construction provides rigidity and edge sharpness on non-ferrous and ferrous workpieces alike.

This end mill is intended for use in professional machine shop environments, toolrooms, and production CNC applications where small-diameter, high-precision cutting is required. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole, adding flexibility in mold work, die work, and fixture machining. Right-hand cut and right-hand spiral orientation are standard for conventional CNC spindle setups. It is sold individually and packaged as a single unit.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 2-flute spiral geometry with 30-degree helix angle for efficient chip clearance
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut, right-hand spiral — compatible with standard CNC spindle rotation
• Uncoated finish suitable for non-ferrous metals, plastics, and general-purpose milling
• 1/8 inch shank fits standard collets and end mill holders on CNC and manual mills

Compatibility

Designed as a standard 1/8 inch shank square end mill compatible with ER collets, end mill holders, and collet chucks sized for 1/8 inch shank tooling on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the full recommended insertion depth in the collet or holder to prevent pullout under cutting load. Verify runout with a dial indicator after clamping, particularly critical at this diameter, before beginning a cut.
