Hertel E8030953 Square End Mill 15/16 in 2 Flute Hss Tin

Product Description

The HERTEL E8030953 is a 2-flute square end mill designed for general-purpose milling operations in machine shop and toolroom environments. Built from M7 high speed steel with a titanium nitride (TiN) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS tooling. The cutter measures 15/16 inches (0.9375 inches) in diameter with a 1-1/2 inches length of cut and a 3-5/8 inches overall length. The 5/8 inches shank diameter suits standard R8, collet chuck, and end mill holder setups. Centercutting geometry allows direct plunge entry into workpiece material without a pre-drilled hole.

This end mill is suited for ferrous and non-ferrous materials in manual mills, CNC machining centers, and knee mills operating at conventional cutting speeds. The right-hand cut and right-hand flute direction are standard for the majority of vertical milling applications. With a 2-flute configuration, chip evacuation is efficient in slotting operations and softer materials where chip load per tooth is a priority. The TiN coating provides a hardness advantage over bare HSS when cutting mild steel, aluminum, and similar workpiece materials at moderate feeds and speeds.

Key Features

• M7 high speed steel construction with TiN coating for extended wear resistance
• Centercutting design allows direct plunge milling without pilot hole
• 2-flute geometry promotes chip clearance in slotting and pocketing
• Right-hand cut and right-hand helix — standard orientation for vertical mills
• 5/8 inches shank fits common collet chucks and end mill holders
• No chipbreaker, variable helix, or extended reach — straightforward general-purpose profile

Compatibility

Designed as a standard-shank square end mill for use in vertical machining centers, knee mills, and manual milling machines that accept a 5/8 inches diameter tool shank via collet, R8, or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the holder. Set tool projection to the minimum length required for the operation to maximize rigidity and reduce deflection. Verify runout at the cutting diameter after tool installation before initiating a cut.
