Hertel E107005601 Square End Mill 7/8 in 2 Flute Hss

Product Description

The HERTEL E107005601 is a 2-flute square end mill ground from M7 high speed steel and intended for general-purpose milling operations in metal cutting environments. The cutter measures 0.875 inches in diameter with a 1.875-inch length of cut, a 0.750-inch straight shank, and a 4.125-inch overall length. The 42-degree spiral helix promotes efficient chip evacuation and smooth cutting action. This tool is uncoated and ships ready for use in standard milling applications without additional surface treatment. Machinists and tool-and-die professionals are the primary users of this style of end mill.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials on manual mills and CNC machining centers. The centercutting geometry allows the tool to plunge directly into the workpiece, expanding its versatility for pocket milling. Right-hand cut and right-hand flute configuration is the industry standard orientation and works with conventional spindle-up setups. Regular length classification makes it appropriate for standard reach applications where extended reach tooling is not required.

Key Features

• M7 high speed steel construction provides good toughness and wear resistance at moderate cutting speeds
• 42-degree helix angle promotes aggressive chip lift and reduced cutting forces
• Centercutting design allows direct plunge entry without a pilot hole
• 2-flute configuration provides larger chip clearance, well suited for softer materials and slotting cuts
• Uncoated finish allows easy regrinding and is compatible with conventional coolant strategies
• Right-hand cut, right-hand spiral flute — standard orientation for conventional milling setups

Compatibility

Designed as a standard straight-shank square end mill for use in collet chucks, end mill holders, and set-screw holders accepting a 0.750-inch shank diameter on manual or CNC milling machines.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist familiar with milling machine operation. Ensure the machine spindle is fully stopped and the power is locked out before installing or removing the tool from the holder. Verify runout with an indicator after seating in the holder, as excessive runout accelerates wear and reduces surface finish quality. Follow shop-standard speeds and feeds for M7 high speed steel based on the workpiece material being cut.
