Guhring 9064840158700 Square End Mill 5/8 in Solid Carbide

Product Description

The GUHRING 9064840158700 is a single-end square end mill designed for high-performance milling in demanding metalworking applications. Built from solid carbide and coated with AlCrN, it delivers heat resistance and wear durability required when cutting high-alloy steel, tough alloys, and soft metals. The tool measures 0.625 inches in diameter with a 1.5-inch length of cut and a 3.75-inch overall length. Four helical flutes with a variable 38/40-degree helix angle improve chip evacuation and reduce chatter across a range of feed and speed conditions. A Weldon flat shank provides positive drive and reduces slippage in standard side-lock holders.

This end mill suits CNC machining centers and manual milling machines used in tool and die, aerospace component, and general precision machining environments. Its extended reach of 1.805 inches and standard length type make it suitable for pocketing, slotting, and peripheral milling where moderate depth and rigidity are both required. The AlCrN coating supports dry and near-dry machining, reducing coolant dependency in production environments. A licensed machinist or CNC operator typically selects this tool for ferrous and non-ferrous materials where surface finish and tool life are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and tough alloys
• AlCrN coating provides high-temperature oxidation resistance and extended tool life
• Variable 38/40-degree helix angle reduces harmonic vibration and improves cut quality
• Four right-hand helical flutes with centercutting capability for plunge and contour operations
• Weldon flat shank for secure seating in side-lock and set-screw tool holders
• Extended reach design accommodates deeper pocket and cavity milling setups

Compatibility

Designed for use with standard 5/8-inch bore side-lock or Weldon-style tool holders. Rated for material applications including high-alloy steel, soft metal, and tough alloy per GUHRING Series 6484 specifications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Ensure the Weldon flat is properly aligned with the set screw in the holder before torquing to the holder manufacturer specification. Inspect collet or holder bore for runout before seating the tool, as excessive runout accelerates flute wear and reduces surface finish quality. Follow shop safety protocols and applicable OSHA machining standards when handling carbide cutting tools.
