Sgs 91256 Corner Radius End Mill 1in 2 Flute Solid Carbide

Product Description

The SGS 91256 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal applications. It features a 1 inch mill diameter, a 1.25 inch length of cut, and a 0.0400 inch corner radius that produces a small blend radius at the cutting edge to reduce chipping and extend tool life. The 2-flute geometry and 45-degree high helix angle promote efficient chip evacuation in softer materials such as aluminum, brass, and copper alloys. The bright, uncoated finish is well-suited for non-ferrous work where coating adhesion or heat buildup is not the primary concern. This end mill is installed and operated by machinists and CNC tooling technicians.

The SGS 91256 belongs to the Series 45C and is configured as a single-end, straight-cylindrical shank tool. It is intended for use in end mill toolholders on CNC machining centers and manual mills. The coarse pitch, right-hand flute direction, and right-hand cutting direction make it a standard choice for roughing passes in non-ferrous metal stock. With a 4 inch overall length, 1 inch shank diameter, and 2.125 inch reach length, it fits conventional toolholding setups without requiring extended-reach adapters for most typical workpiece depths.

Key Features

• 0.0400 inch corner radius reduces edge chipping and blends corner transitions on finished profiles
• 45-degree high helix angle promotes chip evacuation in non-ferrous metals
• Solid carbide construction provides rigidity and wear resistance over high-speed roughing passes
• Bright, uncoated finish suited for aluminum, brass, copper, and similar non-ferrous alloys
• Straight-cylindrical shank with h6 tolerance for precise fitment in standard end mill toolholders
• 2-flute, coarse pitch geometry supports aggressive material removal rates in softer workpiece materials

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece material application is non-ferrous metal. This tool is not rated for ferrous or hardened materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Confirm the toolholder bore matches the 1 inch shank diameter and that the holder is clean and free of burrs before seating the tool. Verify spindle speed and feed rate parameters against the material and depth of cut before engaging the workpiece. Do not use this end mill on ferrous or hardened materials, as it is specified exclusively for non-ferrous applications.
