Gws 122670 Square End Mill 3/8 in 7 Flute Solid Carbide

Product Description

The GWS 122670 is a 7-flute solid carbide square end mill designed for high-performance milling in a wide range of materials. It measures 3/8 inch in diameter with a 0.437-inch length of cut, a 2-inch overall length, and a 3/8-inch square shank held to h6 tolerance. The variable helix geometry and chipbreaker features work together to reduce harmonics, improve chip evacuation, and extend tool life. The nACRo coating adds thermal and wear resistance, making this end mill well suited for demanding cutting applications across ferrous and non-ferrous workpiece materials.

This end mill is built for professional machinists and tooling specialists working in CNC milling environments. It is applicable to workpiece material codes H, K, M, N, P, and S, covering a broad spectrum including steels, cast irons, stainless steels, non-ferrous metals, long-chipping materials, and heat-resistant superalloys. The single-end, right-hand cutting and right-hand flute configuration makes it a standard fit for conventional CNC machining center setups. The upcut flute type promotes chip clearing away from the workpiece surface.

Key Features

• 7-flute geometry increases feed rates and improves surface finish compared to lower-flute-count alternatives
• Variable helix design reduces chatter and vibration during cutting
• Chipbreaker feature aids chip control and reduces cutting forces
• nACRo coating provides elevated thermal resistance and extended wear life
• Submicron carbide grade delivers fine grain structure for edge toughness and hardness
• h6 shank tolerance ensures consistent, accurate tool holding in standard collets and chucks

Compatibility

Rated for workpiece material codes H, K, M, N, P, and S. Fits standard 3/8-inch collets, end mill holders, and shrink-fit toolholders used in CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill. Confirm the collet or holder is clean and undamaged before seating the shank. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece material being machined.
