Hertel 750342 Square End Mill 3/16 in 2 Flute Carbide Tin

Product Description

The HERTEL 750342 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tooling, and machining environments. With a 3/16-inch (0.1875 inch) mill diameter and a 5/8-inch (0.625 inch) length of cut, this single-end tool is built for tight-tolerance work in ferrous and non-ferrous materials. The micrograin carbide substrate provides hardness and wear resistance, while the TiN coating reduces friction and extends tool life in production cutting. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is installed and operated by machinists, tool and die makers, and CNC programmers working on vertical mills and machining centers.

The 750342 suits light to medium slotting, profiling, and peripheral milling applications where a small-diameter tool with consistent edge geometry is required. Its 3/16-inch shank diameter matches the mill diameter for direct collet or end mill holder mounting. The 2-inch overall length keeps the tool compact, minimizing deflection in close-tolerance setups. Right-hand cutting and right-hand flute direction follow standard conventions for most VMC and knee mill spindle configurations. This tool is appropriate for job shops, production floors, and tool rooms handling aluminum, steel, and similar materials.

Key Features

• Solid carbide micrograin construction for hardness and dimensional stability
• TiN coating reduces friction and improves wear resistance at the cutting edge
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Centercutting geometry allows plunge entry into workpiece material
• 2-flute design provides maximum chip clearance in slotting and profiling cuts
• Single-end configuration with matched shank and mill diameter for direct collet mounting

Compatibility

Designed for use in standard collet chucks, end mill holders, and shrink-fit holders with a 3/16-inch bore, compatible with vertical machining centers and knee mills using right-hand spindle rotation.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and verify runout with a dial indicator before beginning a cut. Follow machine manufacturer guidelines and applicable shop safety procedures when operating end mills at speed.
