Sgs 35709 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The SGS 35709 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 1/2-inch mill diameter, a 0.0600-inch corner radius, and three helical flutes ground to a right-hand cutting direction. The tool is coated with Titanium Diboride (TiB2), also designated Ti-NAMITE-B, which reduces friction and extends tool life when cutting aluminum, copper, brass, and similar non-ferrous materials. With a 38-degree high helix angle and a coarse pitch, this end mill is optimized for aggressive roughing passes. A licensed machinist or toolroom technician typically selects this tool for production and job-shop environments.

The SGS 35709 is suited for roughing operations on non-ferrous metals in both manual and CNC milling setups. Its long-length configuration, with a 1.8750-inch length of cut and 4.0000-inch overall length, provides extended reach into deep pockets and slots while maintaining rigidity through the 1/2-inch straight-cylindrical shank. The single-end design and Series 43CR geometry are intended for use with standard end mill holders. This tool is a practical choice for shops machining aluminum plate, billets, or extrusions where chip clearance and surface finish in the roughing stage are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous cutting
• TiB2 (Titanium Diboride) coating reduces built-up edge and friction on aluminum and copper alloys
• 0.0600-inch corner radius protects the cutting edge and improves corner strength in pocketing operations
• 38-degree high helix angle promotes efficient chip evacuation during roughing passes
• Long-reach geometry with 1.8750-inch length of cut suits deep pocket and slot milling
• Right-hand flute direction and right-hand cutting orientation; compatible with standard CNC end mill holders

Compatibility

Designed for use with standard end mill holders accepting a 1/2-inch straight-cylindrical shank. Optimized for primary workpiece materials coded N (non-ferrous metals) per the SGS Series 43CR classification.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the shank fully in a clean, properly sized end mill holder and torque the retention mechanism to the holder manufacturer's specification. Verify spindle runout before cutting, as excessive runout accelerates corner radius wear and reduces part accuracy. Always confirm cutting parameters - speed, feed, and depth of cut - from the tool manufacturer's application data for the specific workpiece material before beginning a roughing operation.
