Guhring 9033030065000 Square End Mill 0.2559 in 2 Flute Carbide

Product Description

The GUHRING 9033030065000 is a solid carbide square end mill designed for precision milling operations in a wide range of materials. It features a 0.2559-inch (6.50 mm) diameter with a matching 0.2559-inch straight cylindrical shank, a 0.5118-inch (13.00 mm) length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. The bright, uncoated carbide construction delivers rigidity and edge retention in demanding cutting environments. This is a single-end, right-hand cut tool with right-hand flute direction, suited for use by machinists and tool-and-die professionals in shop and production settings.

This end mill is rated for use in workpiece material categories K (cast iron), M (stainless steel), N (non-ferrous), P (steel), and S (superalloys and titanium), making it a versatile choice for general-purpose milling, slotting, and profiling. The regular length type and straight-cylindrical shank keep it compatible with standard collet and end mill holder tooling systems. It is center-cutting, allowing for plunge entry when the application requires it. Overall length is 60.00 mm, with a reach length of 24.00 mm, supporting access in moderate-depth applications without excessive overhang.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.2559-inch (6.50 mm) cutting diameter with h10 diameter tolerance for consistent fit
• 2-flute spiral design with 30-degree helix angle promotes chip evacuation and smooth cutting action
• Center-cutting geometry allows direct plunge entry into workpiece
• Bright/uncoated finish — no coating buildup to affect critical tolerances
• Straight cylindrical shank (h6 tolerance) fits standard ER collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill within the GUHRING Series 3303 product line, compatible with standard straight-cylindrical collet systems accepting a 0.2559-inch (6.50 mm) shank diameter.

Installation Notes

Installation is performed by machinists using a milling machine or machining center equipped with a compatible collet or end mill holder rated for the 0.2559-inch shank diameter. Verify spindle is fully stopped and machine is in a locked-out state before changing tooling. Torque the collet nut to the holder manufacturer's specification — do not over-tighten solid carbide tooling, as carbide is brittle and susceptible to fracture under lateral shock loads. Inspect the cutting edges for chips or damage before each use.
