Precision Twist Drill 5110015 Hss End Mill 4 Flute 5/8 in

Product Description

The PRECISION TWIST DRILL 5110015 is a high-speed steel (HSS) end mill designed for material removal, profiling, and slotting operations in metalworking and machining applications. Built with a Weldon shank for secure tool holding and reduced slippage under load, this end mill features a 4-flute geometry that balances chip evacuation with surface finish quality. The cutting diameter is 5/8 inches with an overall length of 3-3/4 inches. HSS construction provides the toughness needed for interrupted cuts and general-purpose milling in ferrous and non-ferrous materials. Machinists and tool-and-die professionals reach for this style of end mill when running manual mills or CNC equipment at moderate speeds and feeds.

This end mill is suited for job shops, maintenance machining, and production environments where a reliable general-purpose cutter is needed. The 4-flute configuration performs well in finishing passes and side milling on steel, aluminum, cast iron, and similar workpiece materials. The Weldon shank design is compatible with side-lock end mill holders commonly found in both manual knee mills and CNC machining centers.

Key Features

• HSS construction provides toughness for general-purpose and interrupted-cut milling
• 4-flute geometry balances material removal rate with finished surface quality
• 5/8 inch cutting diameter for medium-range profiling and slotting operations
• Weldon shank design seats securely in side-lock tool holders to resist pullout
• Overall length of 3-3/4 inches provides adequate reach for most standard setups
• Sold individually — minimum order quantity of one

Compatibility

Designed for use with standard side-lock Weldon shank end mill holders accepting a 5/8 inch shank, compatible with manual milling machines and CNC machining centers equipped with appropriate tooling.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Secure the Weldon shank firmly in the side-lock holder using the set screw against the flat on the shank before operation. Inspect the cutting edges for chips or wear before each use, and follow applicable shop safety practices and machine manufacturer guidelines for speed and feed selection. Tool holding and setup work is typically performed by a machinist or tool-and-die professional.
