Guhring 9067750031700 Square End Mill 1/8 Inch 3-flute

Product Description

The GUHRING 9067750031700 is a 3-flute square end mill designed for combined roughing and finishing operations in a single tool pass. Part of the Series 6775 lineup, it features a variable helix angle design — with 39, 40, and 41-degree flutes — that reduces harmonic chatter and improves surface finish without a dedicated finishing pass. The uncoated carbide construction suits a range of base materials where coating buildup or heat sensitivity would be a concern. With a 1/8-inch cutting diameter, 1/2-inch length of cut, and 2-inch overall length, this end mill fits compact tooling envelopes on manual mills and CNC machining centers alike.

This end mill is intended for precision material removal in tight features — slots, pockets, and profiling cuts — where both stock removal rate and finish quality matter in the same operation. The single-end, right-hand cut configuration with right-hand flute direction is standard for conventional CNC and manual milling setups. The 1/8-inch shank diameter fits standard collets and end mill holders used across most light-duty machining centers. Regular length geometry keeps deflection low at this diameter, which is critical for accurate feature dimensions in ferrous and non-ferrous work materials.

Key Features

• Variable helix angles of 39, 40, and 41 degrees reduce chatter and improve surface finish
• 3-flute geometry balances chip evacuation with cutting edge count for combined roughing and finishing
• Square end profile suits slot milling, pocket milling, and sharp-corner profiling
• Uncoated construction avoids coating buildup in materials sensitive to coated tooling
• Regular length body minimizes deflection at the 1/8-inch diameter
• Single-end design — Series 6775 classification for direct OEM replacement ordering

Compatibility

Designed as a direct-fit replacement or upgrade for 1/8-inch shank end mills in standard ER collet systems and end mill holders used on CNC machining centers and manual knee mills. Part of the GUHRING Series 6775 family.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing any end mill. Seat the shank fully into the collet or holder to the recommended minimum engagement depth for the holder type before torquing the collet nut. Inspect the shank and collet bore for chips or damage before each use to prevent runout issues at this small diameter.
