Guhring 9199590095200 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The GUHRING 9199590095200 is a solid carbide, 4-flute square end mill designed for precision milling in demanding metalworking applications. It measures 3/8 inch in diameter with a 1 inch length of cut and a 2.5 inch overall length. The tool features a variable helix design with angles ranging from 35 to 38 degrees, which reduces harmonic vibration and improves chip evacuation during aggressive cuts. A FIREX finish provides enhanced heat resistance and lubricity, extending tool life in difficult materials. This is a single-end, centercutting tool with a right-hand cut and right-hand helical flute configuration, suitable for slotting, profiling, and plunge operations.

This end mill is engineered for milling cast iron, stainless steel, carbon steel, and high-temperature alloys, corresponding to workpiece material codes K, M, P, and S, with secondary suitability for hard materials (code H). The straight cylindrical shank at 3/8 inch diameter fits standard ER collets and end mill holders common in CNC machining centers and manual mills. It is well suited for shops running tight-tolerance work in aerospace, die and mold, and general precision machining environments.

Key Features

• Variable helix angles of 35 and 38 degrees reduce chatter and improve surface finish
• FIREX coating provides thermal resistance and reduced friction for extended tool life in hard materials
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Solid carbide construction delivers rigidity and wear resistance superior to HSS tooling
• Right-hand cut and right-hand helical flutes for standard CNC and manual mill compatibility
• Mill diameter tolerance e8 and shank diameter tolerance h6 ensure consistent fit and runout control

Compatibility

Part of GUHRING Series 19959. Rated for primary workpiece materials cast iron (K), stainless steel (M), carbon and alloy steel (P), and high-temperature superalloys (S), with secondary rating for hard materials (H).

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the retention mechanism to the machine tool manufacturer's specification. Inspect runout with a dial indicator before beginning cuts. Never exceed the tool's rated depth of cut or feed rate for the workpiece material being machined.
