Hertel GH070064 Square End Mill 1 in 2 Flute Hss Tin

Product Description

The HERTEL GH070064 is a 1-inch diameter square end mill designed for general-purpose milling in ferrous and non-ferrous metals. Manufactured from M7 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life in production and job-shop environments. The 2-flute configuration with a 42-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 4.5 inches overall length with a 2-inch length of cut, this is a standard-reach tool suited to a wide range of vertical and horizontal milling machine setups. The centercutting geometry allows direct plunge entry without pre-drilling. Installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited to peripheral milling, slotting, and plunge operations in steel, cast iron, aluminum, and similar materials. The right-hand cut, right-hand spiral flute design is compatible with standard R8, CAT, and BT toolholders using a 1-inch collet or end mill holder. The regular-length body fits within standard work envelopes on knee mills and vertical machining centers. It is sold individually and is appropriate for production runs, maintenance machining, and prototype work.

Key Features

• M7 high speed steel construction for toughness in interrupted cuts and variable-hardness workpieces
• TiN coating increases surface hardness and reduces friction for longer tool life
• 42-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design enables direct plunge milling without a pilot hole
• Right-hand cut and right-hand spiral flute for use with standard spindle rotation
• 2-flute geometry provides clearance for chip evacuation in slotting operations

Compatibility

Designed as a standard 1-inch shank square end mill compatible with 1-inch end mill holders, collet chucks, and similar toolholding systems used on vertical knee mills, bed mills, and CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before inserting or removing the tool. Secure the shank to the specified holder torque per the toolholder manufacturer guidelines and verify runout before cutting. Inspect the cutting edges for chipping after use on hardened or abrasive materials.
