Guhring 9068090015900 Corner Radius End Mill 1/16 in

Product Description

The GUHRING 9068090015900 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built from ultra fine grain carbide and coated with GUHRING's Durox finish, this single-end, centercutting tool runs a 1/16 inch (1.59 mm) mill diameter with a 7.95 mm length of cut and a 2 inch overall length. The straight-cylindrical shank measures 4 mm in diameter with an h5 tolerance, while the mill diameter holds an h8 tolerance for precise, repeatable fitment in end mill holders. The high-helix, three-flute helical geometry supports both roughing and finishing passes in a single setup, making it a practical choice for machinists working tight features and extended-reach applications.

This end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, as well as secondary applications in hard materials. Its extra long length type and 14 mm reach length make it appropriate for deep-pocket milling, slotting, and profiling where standard-length tools cannot reach. The coarse pitch and right-hand flute and cutting direction are conventional for CNC machining centers and manual mills using end mill holders. Coolant-through capability supports chip evacuation and tool life when running at elevated feeds and speeds in abrasive or gummy workpiece materials.

Key Features

• Ultra fine grain solid carbide substrate for rigidity and wear resistance in hard and abrasive materials
• Durox coating improves surface hardness and thermal resistance for extended tool life
• Centercutting geometry allows direct plunge entry into workpiece material
• Coolant-through design supports chip flushing in deep-pocket and extended-reach cuts
• Three-flute high-helix configuration balances chip evacuation with wall finish quality
• h8 mill diameter tolerance and h5 shank tolerance ensure accurate seating in end mill holders

Compatibility

Designed for use with standard end mill holders. Compatible with machining applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per material codes P, M, K, N, S, and H.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's spindle and toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the end mill. Confirm shank seating depth in the holder meets the manufacturer's minimum engagement recommendation to prevent pullout under cutting loads. Verify coolant-through passages are clear and aligned if using through-tool coolant delivery.
