Guhring 9067740158700 Corner Chamfer End Mill 5/8 in

Product Description

The GUHRING 9067740158700 is a solid carbide corner chamfer end mill built for high-demand metal removal in steel, stainless steel, superalloys, and titanium. It features a 5/8-inch cutting diameter, a 2-1/4-inch length of cut, and a 4-flute, right-hand helical geometry with a 48-degree helix angle. The nano-A AlTiN PVD coating provides thermal and wear resistance for aggressive cutting conditions. At 5 inches overall length and a Weldon flat shank, this is an extra-long tool intended for deep-reach applications. It is centercutting, enabling plunging and helical interpolation entries. Licensed machinists and CNC programmers working in production and job-shop environments are the primary users.

This end mill is suited for shouldering, slotting, ramp-down milling, helical interpolation, drill milling, and plunging and recessing operations. It performs across a normal pitch configuration optimized for both roughing and finishing passes. Primary workpiece materials include steel (P), stainless steel (M), and superalloys and titanium (S). Secondary applications cover non-ferrous metals (N). The 45-degree chamfer angle with a 0.007-inch chamfer width adds a controlled edge break on part features in a single pass, reducing the need for a secondary deburring operation.

Key Features

• Solid carbide construction with nano-A AlTiN PVD coating for heat and wear resistance in ferrous and exotic alloys
• 48-degree high-helix angle promotes chip evacuation and reduces cutting forces in deep-reach cuts
• Centercutting design supports plunging, helical interpolation, and drill milling entries
• 0.007-inch chamfer width at 45 degrees breaks edges in the same pass as profiling or slotting
• Weldon flat shank with h6 tolerance provides positive drive and accurate tool holding
• Extra-long 5-inch OAL with 2-1/4-inch reach length for deep pocket and deep-wall applications

Compatibility

Designed as a direct-fit replacement for GUHRING Series 6774 corner chamfer end mills. Compatible with standard 5/8-inch end mill holders and Weldon-flat set-screw holders. Suitable for CNC machining centers running steel, stainless steel, superalloys, titanium, and non-ferrous metals.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and the tool path program verified before loading the tool into the holder. Confirm the Weldon flat is properly seated against the set screw to prevent axial pull-out under plunge or helical loads. Verify runout with a dial indicator after tool-change to maintain diameter tolerance within the h10 specification.
