Precision Twist Drill 5110012 Hss End Mill 4 Flute 0.75 in

Product Description

The PRECISION TWIST DRILL 5110012 is a high-speed steel (HSS) end mill designed for material removal, profiling, and milling operations in metalworking and machining applications. Built with a 4-flute configuration and a Weldon shank, it delivers stable tool holding and smooth cutting performance. The cutting diameter is 0.75 inches with an overall length of 3.625 inches. HSS construction provides the toughness needed for general-purpose milling on a range of ferrous and non-ferrous materials. This end mill is sold individually and is suited for use in manual mills and CNC machining centers.

This end mill is used in job shops, maintenance machining, and production environments where consistent material removal is required. The Weldon shank design provides a flat for set-screw clamping, reducing tool pullout during side-load cutting operations. The 4-flute geometry makes it well suited for finishing passes and harder materials where chip load per flute is manageable. Machinists and toolroom technicians are the primary installers and operators of this tool.

Key Features

• High-speed steel (HSS) construction for toughness across a range of materials
• 4-flute geometry suited for finishing cuts and harder workpiece materials
• Weldon shank with flat for positive set-screw engagement and reduced pullout
• 0.75 inch cutting diameter for standard milling applications
• 3.625 inch overall length for reach in typical milling setups

Compatibility

Designed as a general-purpose HSS end mill compatible with Weldon-style tool holders sized for 0.75 inch shank diameters on manual knee mills and CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before inserting or removing the end mill from the tool holder. Secure the Weldon flat against the set screw and torque the holder per the tool holder manufacturer's specification. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
