Precision Twist Drill 5110376 Hss End Mill 2 Flute 0.5 in

Product Description

The PRECISION TWIST DRILL 5110376 is a two-flute high-speed steel end mill with a Weldon shank, designed for milling, slotting, and profiling operations in metal fabrication and machining environments. The cutting diameter measures 0.5 inches with an overall length of 4.125 inches, making it a compact, rigid tool suited for precision material removal. High-speed steel construction provides the toughness needed to handle interrupted cuts and varying feed rates without chipping. Machinists and tool-and-die professionals rely on this style of end mill for general-purpose work across a range of workpiece materials.

This end mill is appropriate for use in vertical milling machines, knee mills, and CNC machining centers where a Weldon shank is the preferred holding method. The two-flute configuration provides good chip clearance, making it well suited for slotting and plunge applications. It is a practical choice for job shops, maintenance machining, and fabrication work requiring consistent, repeatable cuts at moderate material removal rates.

Key Features

• High-speed steel construction for toughness and resistance to chipping during interrupted cuts
• Two-flute design promotes efficient chip evacuation during slotting and plunge milling
• Weldon shank provides positive drive and resists pullout in standard end mill holders
• 0.5 inch cutting diameter suits a wide range of common milling operations
• Overall length of 4.125 inches offers rigidity while accommodating standard setups

Compatibility

Designed as a direct-fit replacement for standard Weldon shank end mill holders accepting a 0.5 inch shank diameter. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill holder torque procedures and machine spindle safety. Power down and lock out the milling machine before inserting or removing the end mill from the holder. Ensure the Weldon shank flat is properly aligned with the set screw in the holder to prevent pullout during operation. Inspect the cutting edges and shank for damage before each use.
