Sgs 36727 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The SGS 36727 is a solid carbide corner radius end mill designed for precision milling in demanding material applications. It features a 3/8 inch diameter with a 0.06 inch corner radius, four flutes, and a 7/8 inch length of cut. The variable helix geometry reduces harmonic vibration during aggressive passes, supporting both roughing and finishing operations in a single tool. A TiN coating improves surface hardness and wear resistance. The 3/8 inch straight-cylindrical shank is sized for standard end mill holders. Overall length is 2.5 inches. This tool is intended for use by machinists and CNC operators working in job shop and production environments.

The SGS 36727 is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The corner radius geometry distributes cutting forces away from sharp edges, extending tool life in high-load cuts. Variable helix and variable index spacing reduce chatter on long-reach setups and thin-wall features. Single-end, right-hand cutting configuration with right-hand flute direction. Centercutting is not supported on this tool, so plunge entry requires a pre-drilled hole or ramp entry. Belongs to the SGS Z-Carb-AP ZPCR series, optimized for the material groups P, M, K, and S per ISO classification.

Key Features

• 3/8 inch cutting diameter with 0.06 inch corner radius for edge protection and smooth floor finishes
• Variable helix and variable index geometry reduce vibration and chatter during aggressive cuts
• Solid micrograin carbide substrate provides rigidity and wear resistance in hard and abrasive materials
• TiN coating increases surface hardness and extends tool life in steel and stainless applications
• 4-flute, single-end design with right-hand cut and right-hand helical flutes
• Fits standard end mill holders with 3/8 inch straight-cylindrical shank (shank tolerance h6)

Compatibility

Designed for use with standard end mill holders accepting a 3/8 inch straight-cylindrical shank. Suitable for CNC machining centers and manual mills set up for right-hand cutting. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium; secondary application covers hard materials.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the tool from the holder. Seat the shank fully in the holder to the recommended grip depth and torque the set screws or collet per the holder manufacturer specifications. This tool does not support direct plunge entry; use ramp or helical interpolation for pocket entry.
