Sgs 33463 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The SGS 33463 is a solid carbide corner radius end mill designed for precision milling operations in metal-cutting applications. It features a 3/8 inch cutting diameter and a 1-1/2 inch length of cut (LOC), with a 0.02 inch corner radius that reduces stress concentration at the cutting edge and improves surface finish. The 3-flute, right-hand spiral geometry paired with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiB2 (titanium diboride) coating increases surface hardness and reduces built-up edge, extending tool life in ferrous and non-ferrous materials. The centercutting design allows for direct plunge entry.

This end mill suits general-purpose and finishing operations in machining centers and CNC milling machines. It is well suited for profiling, slotting, and contouring in materials where a corner radius is required to prevent chipping or stress fractures at part edges. The coarse pitch classification supports applications where chip load management is a priority. Machinists and tooling professionals working in job shops, production environments, or prototype machining will find this tool applicable across a range of ferrous and non-ferrous workpieces.

Key Features

• 3/8 inch cutting diameter with 0.02 inch corner radius for edge strength and surface finish improvement
• Solid carbide construction for rigidity and wear resistance
• TiB2 coating reduces friction and extends tool life in demanding cuts
• 3-flute, right-hand spiral with 38-degree helix for efficient chip removal
• Centercutting design enables direct plunge milling
• 3/8 inch shank diameter and 4 inch overall length (OAL) for standard toolholder compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3/8 inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before production cutting, as excessive runout will accelerate wear and degrade surface finish.
