Sgs 38170 Corner Radius End Mill 3/8 in 4 Flute Altin

Product Description

The SGS 38170 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. It features a 3/8-inch diameter, a 0.015-inch corner radius, and 4 flutes arranged in a right-hand helical configuration. The tool is coated with AlTiN (Ti-NAMITE-A designation), which provides thermal resistance and extended tool life when cutting ferrous and exotic alloy materials. At 2.5 inches overall length with a 1-inch length of cut, this single-end mill is sized for standard vertical and horizontal machining center work. A Weldon flat shank ensures secure seating in compatible end mill holders.

This end mill is suited for roughing and finishing operations across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, as well as hard materials. The Series 01C design with micrograin carbide substrate and variable index geometry reduces chatter and improves surface finish in production and job-shop environments. It is a practical choice for machinists running CNC mills where consistent corner geometry and coating durability are priorities.

Key Features

• AlTiN coating (Ti-NAMITE-A) for high-heat resistance and extended tool life in steel and superalloy cuts
• 0.015-inch corner radius reduces stress concentration and improves edge durability at workpiece corners
• Solid micrograin carbide substrate for rigidity and wear resistance
• Variable index flute spacing reduces harmonic vibration during aggressive cuts
• Weldon flat shank for positive drive in end mill holders
• Right-hand cut and right-hand flute direction; suitable for standard spindle rotation

Compatibility

Designed for use with standard end mill holders accommodating a 3/8-inch Weldon flat shank. Compatible with CNC vertical and horizontal machining centers operating with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the Weldon flat shank fully into the end mill holder and torque the set screw according to the holder manufacturer specifications before operation. Confirm spindle rotation direction is right-hand before engaging the cut. Inspect the corner radius and cutting edges for chips or wear before each use, particularly after cuts in hard or abrasive materials.
