Guhring 9068090030000 Corner Radius End Mill 3mm Solid Carbide

Product Description

The GUHRING 9068090030000 is a solid carbide corner radius end mill designed for demanding material removal in steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. It measures 3 mm in diameter with a 15 mm length of cut and a 57 mm overall length. The three-flute, right-hand helical geometry is ground from ultra fine grain carbide and finished with a Durox coating to extend tool life under high-speed conditions. The high helix style promotes efficient chip evacuation, and the coarse pitch supports both roughing and finishing passes in a single setup. Coolant-through capability allows for effective heat management at the cutting zone.

This end mill is suited for machining operations where tight tolerances and surface integrity are required across a range of workpiece materials. The 6 mm straight-cylindrical shank mounts directly into standard end mill holders, making it practical for CNC machining centers handling production work in steel components, aerospace-grade titanium alloys, and cast iron parts. The extra-long length type and 24 mm reach length allow access to deeper features without requiring extended-reach tooling assemblies. Its centercutting design supports both plunge and ramping entries.

Key Features

• Solid carbide construction in ultra fine grain grade for rigidity and wear resistance
• Durox coating for thermal protection and extended tool life in ferrous and superalloy materials
• Coolant-through design for heat management at the cutting edge
• Three-flute, high helix, coarse pitch geometry supports roughing and finishing in a single tool
• Centercutting capable — supports plunge milling and ramping entries
• Mill diameter tolerance h8 and shank diameter tolerance h5 for consistent fit in end mill holders

Compatibility

Designed for use with standard end mill holders. Compatible with primary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and superalloys and titanium. Secondary workpiece material compatibility includes hard materials.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the end mill. Seat the 6 mm straight-cylindrical shank fully into the end mill holder and torque the retention mechanism per the holder manufacturer's specifications. Verify runout with a dial indicator before production use to confirm proper seating and avoid premature edge wear.
