Sgs 39027 Square End Mill 7/32 in 4 Flute Solid Carbide

Product Description

The SGS 39027 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. Built from micrograin carbide and coated with titanium carbonitride (TiCN), it delivers enhanced wear resistance and longer tool life compared to uncoated carbide. The 7/32 inch (0.2188 inch) cutting diameter and 4-flute configuration support efficient material removal while maintaining a clean, square shoulder. With a 30-degree helix angle and right-hand cutting direction, this end mill is suited for a wide range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.

This end mill is a single-end, regular-length Series 1 tool with a 5/8 inch length of cut, a 1/4 inch straight-cylindrical shank, and a 2-1/2 inch overall length. Its variable index geometry reduces chatter and improves surface finish across multiple material groups, including cast iron, non-ferrous metals, stainless steel, and high-temperature alloys. It is center-cutting, allowing plunge entry. Typical applications include slotting, profiling, and contouring in production and prototype machining environments.

Key Features

• TiCN coating for improved hardness and wear resistance over uncoated carbide
• Micrograin solid carbide construction for rigidity and edge retention
• 4-flute, variable index design reduces vibration and chatter during cuts
• 30-degree right-hand spiral helix for efficient chip evacuation
• Center-cutting capable — supports direct plunge entry without pre-drilling
• Straight-cylindrical 1/4 inch shank fits standard collets and end mill holders

Compatibility

Designed for use across multiple workpiece material groups including cast iron (K), non-ferrous metals (N), stainless steel (M), steel (P), heat-resistant and titanium alloys (S), and hardened materials (H), as indicated by primary workpiece material codes in the product specifications.

Installation Notes

Installation is performed by qualified machinists. Secure the shank in a properly sized collet or end mill holder, ensuring the shank is fully seated before torquing. Verify spindle speed and feed rate are appropriate for the workpiece material and cutting diameter before engaging the cut. Always power down and lock out the machine spindle before changing tooling.
