Guhring 9030770127000 Square End Mill 4 Flute Carbide

Product Description

The GUHRING 9030770127000 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built to Series 3077 specifications, this single-end tool features a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 3.5 inch overall length. The variable helix design, with angles ranging from 40 to 42 degrees, reduces harmonic vibration during cutting and promotes smooth chip evacuation. With 4 spiral flutes and a right-hand cut and flute configuration, this end mill is suited for use in CNC machining centers and manual mills. It is installed and operated by machinists and tool-and-die professionals working across general and precision manufacturing environments.

This end mill is well suited for milling non-ferrous and non-metallic materials, as indicated by its primary workpiece material code N. The 0.5 inch Weldon flat shank provides positive rotational drive in standard end mill holders and side-lock toolholders. The centercutting geometry allows for plunge milling operations in addition to peripheral and slot milling. The uncoated, bright finish makes it a practical choice for applications where coating is unnecessary or where regrinding is anticipated. It fits standard 0.5 inch bore collets and holders common to most CNC and manual machining setups.

Key Features

• Variable helix angles of 40 and 42 degrees reduce chatter and improve surface finish
• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• Centercutting design enables plunge entry without a pre-drilled hole
• Weldon flat shank ensures positive drive in side-lock toolholders
• Right-hand cut and right-hand flute geometry for use in standard spindle rotation
• Bright uncoated finish compatible with reground tooling programs

Compatibility

Designed as an OEM-style replacement or direct application tool for standard 0.5 inch end mill holders, collet chucks, and Weldon-style side-lock holders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Before mounting, verify the spindle and holder are clean and free of chips or burrs that could affect runout. Secure the Weldon flat against the set screw in the toolholder to the appropriate clamping torque specified by the holder manufacturer. Confirm tool projection and runout with a dial indicator before beginning cuts, and select feeds and speeds appropriate to the workpiece material per GUHRING published cutting data.
