Sgs 02346 Square End Mill 0.039 in 4 Flute Solid Carbide Altin

Product Description

The SGS 02346 is a 4-flute square end mill designed for precision milling operations in demanding metalworking applications. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers high heat resistance and extended tool life in ferrous and hardened materials. The cutting diameter measures 0.039 inches with a length of cut of 0.117 inches and an overall length of 1.5 inches. A 30-degree right-hand helix with spiral flutes promotes efficient chip evacuation and smooth cutting action. This tool is installed and operated by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

The SGS 02346 is suited for high-speed finishing and semi-finishing passes in steel, stainless steel, cast iron, and similarly hard materials. Its centercutting geometry allows it to plunge directly into workpieces, making it practical for slot milling, profiling, and pocket operations. The 0.125-inch straight cylindrical shank fits standard collet systems commonly found in CNC machining centers and manual knee mills. This tool is a regular-length end mill appropriate for general-purpose close-tolerance work where a small-diameter tool is required.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides thermal barrier and extends tool life at elevated cutting speeds
• 4-flute spiral configuration supports efficient chip evacuation and improved surface finish
• 30-degree right-hand helix angle balances cutting forces and reduces chatter
• Centercutting design enables direct plunge entry into workpiece material
• Straight cylindrical shank with h6 tolerance for accurate collet engagement

Compatibility

Designed as an OEM-style replacement or direct-use square end mill compatible with standard collet-style tool holders accepting a 0.125-inch shank diameter on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following established toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. Inspect the cutting edges for chips or coating damage before each use, as micrograin carbide tools are brittle and can fracture if dropped or improperly stored.
