Sgs 09255 Corner Radius End Mill Head 4 Flute Carbide

Product Description

The SGS 09255 is a solid micrograin carbide corner radius end mill head designed for both roughing and finishing operations on CNC machining centers and manual mills. It features 4 flutes with a right-hand cutting and flute direction, a variable index, and a variable helix geometry that reduces chatter and improves chip evacuation. The corner radius measures 0.0300 inches and the length of cut is 0.1870 inches. Center-cutting capability allows plunge entry without a pre-drilled hole. Weighing just 0.013 pounds, this compact head is suited for precision work in demanding metal removal applications.

This end mill head is used in applications requiring a blend of material removal rate and surface finish quality. The spiral flute design with a corner radius end type is common in aerospace, die and mold, and general metalworking environments. The roughing and finishing classification means a single tool can handle stock removal passes and finish passes, reducing tool changes. It is installed and used by machinists and CNC operators working with ferrous and non-ferrous materials where micrograin carbide tooling is specified.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• 4-flute spiral design with variable helix and variable index for reduced chatter
• Corner radius end type with 0.0300-inch radius for edge strength and surface finish
• Center-cutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle use
• Rated for both roughing and finishing material removal

Compatibility

Designed as an OEM-style replacement corner radius end mill head for use in compatible modular tooling systems accepting this head geometry and size profile.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer torque and clamping procedures for modular end mill systems. Power down and lock out the machine spindle before seating or removing the head. Inspect the mating interface and threads for chips or damage before installation. Follow applicable shop safety standards and use appropriate personal protective equipment when handling carbide cutting tools.
