Hertel E1043932 Square End Mill 1/2 in 3 Flute Hss

Product Description

The HERTEL E1043932 is a single-end square end mill designed for general-purpose milling operations in a wide range of ferrous and non-ferrous materials. Manufactured from M7 high speed steel, it features a 1/2 inch cutting diameter with a 1 inch length of cut and a 3/8 inch straight shank for secure tool holding. The 30-degree spiral helix and three-flute geometry promote efficient chip evacuation and smooth cutting action. At 2-11/16 inches overall length, this uncoated end mill is a standard regular-length tool suited for setup and production work on manual mills and CNC machining centers. Installation and use are performed by machinists, tool and die makers, and maintenance technicians.

This end mill is intended for slotting, profiling, and peripheral milling in shop and production environments. The centercutting design allows direct plunge entry into the workpiece without pre-drilling. Right-hand cut and right-hand flute configuration matches standard spindle rotation on the vast majority of vertical milling machines and machining centers. It is well suited to light-to-moderate material removal in steel, aluminum, cast iron, and similar materials where an uncoated HSS tool is appropriate.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general milling applications
• Centercutting geometry allows direct plunge milling without a pre-drilled entry hole
• 30-degree helix angle promotes efficient chip flow and reduces cutting forces
• Three-flute design balances chip clearance with rigidity on smaller-diameter tools
• Uncoated finish suitable for use with cutting fluids on a broad range of workpiece materials
• Regular length profile for standard reach slotting and profiling operations

Compatibility

Designed as a standard single-end square end mill with a 3/8 inch straight shank, compatible with any tool holder or collet accepting a 3/8 inch shank diameter, including ER collet chucks, end mill holders, and Weldon-style side-lock holders on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm that cutting fluid or lubrication is appropriate for the workpiece material and operation.
