Sgs 38237 Corner Radius End Mill 5/16 in 2 Flute Carbide

Product Description

The SGS 38237 is a solid carbide corner radius end mill designed for precision material removal in demanding machining applications. It features a 5/16 inch diameter cutting head with a 0.045 inch corner radius, which reduces stress concentrations at the cutting edge and extends tool life in interrupted or continuous cuts. The 2-flute, right-hand helical geometry provides efficient chip evacuation. With a 13/16 inch length of cut and 2.5 inch overall length, this single-end tool fits standard end mill holders and is suited for CNC milling centers and manual knee mills run by machinists and toolroom operators.

This end mill is rated for roughing 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 as a secondary application. The coarse pitch and medium helix angle make it well-suited for high-material-removal-rate passes where chip load management matters. The straight-cylindrical shank fits 5/16 inch end mill holders directly, with no adapter required in most setups.

Key Features

• 5/16 inch mill diameter with 0.045 inch corner radius for edge strength and reduced chipping
• Solid micrograin carbide construction for rigidity and wear resistance in ferrous and superalloy cuts
• 2-flute right-hand helical geometry with coarse pitch for effective chip evacuation during roughing
• Uncoated bright finish suitable for use with cutting fluids on steel and stainless steel
• Single-end centercutting design allows plunge entry and slot milling
• Straight-cylindrical shank sized at 5/16 inch to fit standard end mill holders

Compatibility

Designed for use with standard end mill holders accepting a 5/16 inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium; secondary application is hard materials.

Installation Notes

Installation is performed by machinists using standard end mill holders; confirm holder bore matches the 5/16 inch shank diameter and torque set screws or collet nuts per the holder manufacturer specification. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after seating to keep deflection within tolerance for corner-radius work. Follow applicable shop safety and machine guarding standards during tool changes.
