Sgs 36611 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The SGS 36611 is a solid carbide corner radius end mill engineered for high-performance material removal in steel, stainless steel, cast iron, superalloys, and titanium. Measuring 0.5 inches in diameter with a 1.25-inch length of cut and a 0.06-inch corner radius, this single-end tool belongs to the SGS Z-Carb-AP ZPCR series. The variable helix geometry and micrograin carbide substrate reduce chatter and extend tool life in both roughing and finishing passes. A TiN coating provides surface hardness and thermal resistance. The Weldon flat shank is compatible with standard end mill holders for secure, repeatable positioning in CNC machining centers and manual mills.

This end mill is suited for production and job-shop environments where steel alloys and hard materials are the primary workpiece. The 4-flute configuration balances chip evacuation with surface finish capability, making it a practical choice for side milling, slotting, and profiling operations. Right-hand cutting direction and right-hand helical flutes are standard. The centercutting designation from supplier data notes no centercutting, so this tool is not intended for direct plunge entry. It is intended for use in end mill holders as specified by the manufacturer.

Key Features

• 0.06-inch corner radius reduces stress concentration and extends edge life at workpiece corners
• Variable helix design minimizes vibration and chatter during aggressive cuts
• Micrograin solid carbide substrate delivers rigidity and wear resistance
• TiN coating adds surface hardness and reduces friction in ferrous materials
• Weldon flat shank provides positive drive and prevents slippage in end mill holders
• Right-hand cut, right-hand flute, helical flute geometry suitable for roughing and finishing

Compatibility

Designed for use with end mill holders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Secondary application covers hard materials. Part of the SGS Z-Carb-AP ZPCR series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before mounting or removing the tool. Secure the Weldon flat shank fully within the holder to the manufacturer-specified engagement depth before tightening set screws. Verify runout with a dial indicator after mounting to confirm proper seating before initiating a cut.
