Hertel E8050030 Square End Mill 15/32 in 2 Flute Hss

Product Description

The HERTEL E8050030 is a double-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The cutter measures 15/32 inch (0.4688 inch) in diameter with a 13/16 inch (0.8125 inch) length of cut, a 1/2 inch shank diameter, and a 3-3/4 inch overall length. Two right-hand spiral flutes and a centercutting geometry allow for plunge entry, slotting, profiling, and peripheral milling without a pre-drilled starting hole.

This end mill suits manual mills, CNC machining centers, and knee mills in job shop, maintenance, and production environments. The double-end configuration provides a second usable cutting end, extending tool life before replacement is required. It is appropriate for face milling, contouring, and slotting cuts in mild steel, aluminum, plastics, and similar materials where HSS tooling is the specified or preferred substrate. Machinists, tool-and-die makers, and maintenance technicians are the typical end users.

Key Features

• High speed steel construction with TiN coating for elevated wear resistance
• Double-end design yields two cutting ends per tool
• Centercutting flute geometry enables direct plunge milling
• Right-hand cut and right-hand spiral flute for standard spindle rotation
• Two flutes promote chip clearance in softer or gummy materials
• 0.8125 inch length of cut accommodates moderate-depth slotting and profiling passes

Compatibility

Designed as a standard replacement or stock end mill for any machine tool accepting a 1/2 inch straight shank, including R8 collet setups, ER collet chucks, and Weldon-style end mill holders commonly found on vertical knee mills and CNC machining centers.

Installation Notes

Installation is performed by a machinist or tool-and-die technician. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or end mill holder and torque the drawbar or set screw to the machine or holder specification. Inspect the cutting edges for chips or coating damage before use, and verify runout with a dial indicator when dimensional accuracy is critical.
