Sgs 38249 Corner Radius End Mill 3/8in 2 Flute Carbide

Product Description

The SGS 38249 is a solid carbide corner radius end mill designed for precision metal removal in demanding machining applications. Built to Series 3CR specifications, it features a 3/8 inch mill diameter, a 1 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner geometry. The micrograin carbide substrate supports higher cutting speeds and feeds, particularly in ferrous and hard materials. This is a single-end, right-hand cut tool with a helical flute design and a Weldon flat shank for positive drive in end mill holders. Machinists and CNC operators in job shops, tool rooms, and production machining environments are the primary installers and users.

The SGS 38249 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its coarse pitch, 2-flute configuration provides good chip clearance in tougher workpiece materials where chip packing is a concern. The 30-degree medium helix balances cutting pressure and surface finish across this range of materials. It is appropriate for roughing material removal operations in both vertical machining centers and manual knee mills using standard end mill holders with Weldon flat retention.

Key Features

• 0.03 inch corner radius reduces edge chipping and workpiece stress risers in roughing passes
• Micrograin solid carbide construction supports aggressive feeds in steel, stainless steel, cast iron, superalloys, and titanium
• 2-flute, coarse pitch design promotes chip evacuation in tough and gummy materials
• Weldon flat shank provides positive, slip-resistant seating in standard end mill holders
• Right-hand cut and right-hand flute direction with 30-degree medium helix angle
• Bright/uncoated finish — no coating thickness to affect dimensional tolerances on close-tolerance work

Compatibility

Designed for use with standard end mill holders. Compatible with applications involving steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials as primary and secondary workpiece materials.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the Weldon flat shank in a compatible end mill holder and confirm the set screw seats fully against the flat before operation. Inspect the spindle taper and holder bore for debris or damage before seating the tool. Follow machine tool manufacturer torque specifications for the holder set screw and verify runout with a dial indicator before taking a first cut.
