Sgs 09187 Corner Radius End Mill Head 4 Flute Carbide

Product Description

The SGS 09187 is a solid carbide corner radius end mill head designed for precision material removal in milling applications. With 4 flutes, a right-hand cutting and flute direction, and a variable index and variable helix geometry, this head delivers both roughing and finishing capability in a single tool. The corner radius measures 0.0100 inches, and the length of cut is 0.1170 inches. The micrograin carbide construction provides hardness and wear resistance suited to demanding machining environments. Center-cutting capability allows plunge entry. This tool head is intended for use by machinists and CNC tooling professionals in shop and production settings.

This corner radius end mill head is suited for use on CNC machining centers and manual mills where a combination of roughing and finishing passes is required in a single operation. The spiral flute design promotes efficient chip evacuation, and the variable helix reduces harmonic vibration during aggressive cuts. The compact geometry, with a 0.5-inch height and 0.5-inch width, fits tight-clearance setups. It is appropriate for a range of metalworking applications where micrograin carbide tooling is specified.

Key Features

• Solid micrograin carbide construction for extended tool life in hard materials
• 4-flute spiral design supports both roughing and finishing in one pass
• Variable index and variable helix geometry reduces chatter and vibration
• Center-cutting capable — allows direct plunge entry into workpiece
• Corner radius of 0.0100 inches reduces stress concentration at cutting edges
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as a replacement-style corner radius end mill head for use with compatible modular end mill systems requiring a 4-flute, right-hand spiral carbide head in this size range.

Installation Notes

Installation should be performed by a qualified machinist familiar with modular tooling systems. Ensure the spindle and tool holder are fully de-energized and locked out before mounting or removing the head. Use the appropriate torque wrench and tool-manufacturer-specified mounting procedure to seat the head correctly — do not overtighten by feel alone. Inspect the seating surface for chips or debris before assembly to ensure accurate runout.
