Sgs 36633 Corner Radius End Mill 5/8 in 9 Flute Solid Carbide

Product Description

The SGS 36633 is a 9-flute solid carbide corner radius end mill designed for high-performance finishing operations in demanding materials. Built to Series 66CR standards, it features a 5/8 inch mill diameter, a 1-5/8 inch length of cut, and a 0.03 inch corner radius that protects the cutting edge and reduces stress concentrations at part corners. The AlTiN (TX) coating delivers thermal resistance and hardness at elevated cutting temperatures. At 3-1/2 inches overall length with a 5/8 inch straight cylindrical shank, this tool is compatible with standard end mill toolholders and is sized for medium to heavy roughing and finishing passes. Machinists and CNC operators working in job shops, tool rooms, and production environments rely on this geometry for consistent edge life in tough materials.

The SGS 36633 is engineered for right-hand cutting and right-hand flute direction with a medium helix and super-close pitch — a configuration well-suited to finishing passes on steel, stainless steel, cast iron, superalloys, and titanium. It also carries a secondary rating for hard materials. The single-end, center-cutting geometry allows plunge entry where required. This end mill is appropriate for use in vertical machining centers and horizontal mills running tight-tolerance finishing cuts where corner integrity and surface finish are critical priorities.

Key Features

• 9-flute super-close pitch configuration reduces chip load per tooth for improved surface finish on finishing passes
• AlTiN (TX) coating provides high thermal resistance and extended tool life in ferrous and superalloy materials
• 0.03 inch corner radius reduces stress risers and protects the cutting edge in corner features
• Micrograin solid carbide substrate delivers rigidity and wear resistance in hard and abrasive workpiece materials
• Right-hand cut, right-hand spiral, medium helix geometry suitable for a broad range of finishing applications
• Straight cylindrical shank with h6 tolerance for accurate, repeatable seating in end mill toolholders

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Rated for secondary use in hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Torque the toolholder to the machine manufacturer specification using calibrated tooling. Verify runout with a dial indicator after clamping before beginning any cutting operation.
