Hertel 750198 Square End Mill 7/8 Inch 4 Flute Carbide

Product Description

The HERTEL 750198 is a solid carbide square end mill designed for precision metal removal in milling operations. It features a 7/8 inch cutting diameter, a 1-1/2 inch length of cut, and a 4 inch overall length with a matching 7/8 inch shank diameter. The four-flute spiral geometry runs a 30-degree helix angle, promoting efficient chip evacuation and a smooth cutting action. This is a right-hand cut, right-hand flute configuration with centercutting capability, meaning it can be used for plunge entry as well as standard peripheral milling. Licensed machinists and toolroom operators are the primary end users of this tool.

This end mill suits a wide range of machining environments including job shops, tool and die operations, and production milling on CNC machining centers or manual knee mills. The uncoated solid carbide construction makes it well suited for non-ferrous metals, cast iron, and general-purpose steel milling where a coated tool is not required. The spiral flute design with a 30-degree helix supports both climb and conventional milling passes and handles interrupted cuts reliably.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Four flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for standard CNC and manual mill spindle rotation
• Uncoated finish suited to applications where coolant is used in place of a hard coating
• Spiral flute design reduces cutting forces and supports consistent surface finish

Compatibility

Designed as a standard 7/8 inch shank square end mill compatible with ER collets, milling chucks, or other toolholding systems accepting a 7/8 inch round shank on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or chuck and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before production use, as excessive runout in solid carbide tooling accelerates chipping and tool failure.
