Hertel 750088 Square End Mill 1 in 2 Flute Solid Carbide

Product Description

The HERTEL 750088 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, this centercutting tool features a 1-inch mill diameter, 2 flutes, and a 30-degree helix angle with right-hand cutting and right-hand flute direction. The spiral flute geometry promotes efficient chip evacuation during full-slot and peripheral milling passes. With a bright uncoated finish, it is well suited for applications where coating is not required or where base carbide performance is preferred. Typically installed by CNC machinists and tool-and-die professionals.

This end mill is used in vertical machining centers, CNC mills, and manual knee mills for slotting, profiling, and plunge cutting operations. The centercutting capability allows direct plunge entry into the workpiece without a pre-drilled hole. The 3-inch length of cut and 6-inch overall length make it suitable for reaching into deeper pockets or stepped features in ferrous and non-ferrous workpiece materials. The 1-inch shank diameter matches standard ER or straight-bore toolholders commonly found in production and job-shop environments.

Key Features

• 1-inch mill diameter with matching 1-inch shank diameter for rigid, concentric tool holding
• Micrograin solid carbide construction for improved wear resistance and edge stability
• 2-flute design with spiral flute geometry supports chip clearance in slotting applications
• 30-degree helix angle balances cutting forces and surface finish quality
• Centercutting geometry enables direct plunge entry without pilot drilling
• Bright uncoated finish — no coating buildup to affect critical tolerances

Compatibility

Designed as a general-purpose solid carbide square end mill for use in standard straight-bore and collet-style toolholders accepting a 1-inch shank diameter.

Installation Notes

This tool is installed by qualified machinists using appropriate toolholders torqued per machine and holder manufacturer guidelines. Confirm spindle runout is within acceptable limits before engaging the workpiece, as excessive runout accelerates edge wear on carbide tools. Always verify feed rate and surface footage are appropriate for the workpiece material and machine rigidity before cutting. Handle carbide end mills carefully — edges are brittle and susceptible to chipping if contacted against hard surfaces during setup.
