Widia 6144151 Square End Mill 3/16in 3 Flute Solid Carbide

Product Description

The WIDIA 6144151 is a solid carbide square end mill designed for precision material removal in metalworking and machining applications. It features a 3/16 inch diameter with a 1 inch length of cut, a 4 inch overall length, and a 30-degree helix angle. The TiAlN coating increases surface hardness and heat resistance, extending tool life during high-speed cutting. With three flutes and right-hand cutting and flute direction, this end mill delivers efficient chip evacuation and surface finish quality. It is suited for use by machinists and tool-and-die professionals running CNC or manual milling equipment.

This end mill is rated for use on steel, stainless steel, cast iron, and non-ferrous metals, covering ISO material groups P, M, K, and N. The straight-cylindrical shank and regular-length profile make it a practical fit for standard collet and end mill holders. The centercutting geometry allows for plunge operations as well as peripheral milling. It is a single-end tool from the WIDIA I3S series, built for shops that require consistent dimensional accuracy on small-diameter cuts.

Key Features

• 3/16 inch diameter with 1 inch length of cut for controlled, precise material removal
• TiAlN coating for elevated heat resistance and extended tool life
• 3-flute design with helical flute geometry for efficient chip evacuation
• 30-degree helix angle balances cutting force and surface finish
• Centercutting capable - supports both plunge and peripheral milling
• Right-hand cut and right-hand flute direction; straight-cylindrical shank

Compatibility

Compatible with steel, stainless steel, cast iron, and non-ferrous metals (ISO groups P, M, K, and N). Designed for use with standard collet systems and end mill holders accepting a 3/16 inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists using a compatible collet chuck or end mill holder on CNC or manual milling equipment. Verify runout and tool holder concentricity before operation to protect the small-diameter shank. Ensure the spindle and machine are fully stopped and locked out before loading or unloading the tool. Follow the machine manufacturer and applicable shop safety guidelines for speeds, feeds, and coolant use.
