Sgs 09121 Corner Radius End Mill Head 4 Flute Carbide

Product Description

The SGS 09121 is a solid carbide corner radius end mill head designed for high-performance metal removal in both roughing and finishing operations. Built from micrograin carbide, it features four flutes with a spiral flute geometry, variable index, and variable helix for reduced chatter and improved chip evacuation. The corner radius measures 0.0150 inches, and the length of cut is 0.1410 inches. This tool is center-cutting and runs in a right-hand cutting direction, making it compatible with standard right-hand spindle setups. Machinists and CNC operators in job shops and production environments rely on this style of end mill head for demanding milling work.

The SGS 09121 is suited for use in CNC milling centers and manual mills where a replaceable end mill head system is in use. Its combination of roughing and finishing capability makes it a practical choice for operations that require material removal followed by surface refinement without a tool change. The micrograin carbide construction handles hardened ferrous and non-ferrous workpiece materials. This tool is packaged individually and is ordered in single-unit quantities.

Key Features

• Solid micrograin carbide construction for durability and wear resistance in demanding cutting conditions
• 4-flute spiral design supports both roughing and finishing material removal
• Variable index and variable helix geometry reduce harmonic vibration and chatter
• Center-cutting configuration allows plunge entry into workpiece material
• Right-hand flute direction and right-hand cutting compatible with standard CNC spindle orientation
• Corner radius end type protects edge integrity and improves surface finish at workpiece corners

Compatibility

Designed as a replacement-style corner radius end mill head for compatible modular end mill systems accepting this head diameter and thread interface. Verify shank system compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is secured in a vise or appropriate fixture before threading on the end mill head. Follow the tooling system manufacturer specifications for torque and engagement depth. Inspect the mating thread and seating surface for chips or damage before assembly.
