Precision Twist Drill 5110010 Hss End Mill 4 Flute 5/8 in

Product Description

The PRECISION TWIST DRILL 5110010 is a high-speed steel (HSS) end mill designed for metal removal in milling operations across a range of industrial and trade applications. Featuring a Weldon shank for positive tool retention and a 4-flute geometry, this end mill delivers stable cutting performance and a quality finish on ferrous and non-ferrous materials. The 5/8 inch cutting diameter and 3-3/8 inch overall length make it well suited for general-purpose slot milling, profile milling, and peripheral milling tasks. Machinists and tool-and-die professionals rely on HSS end mills like this one for consistent performance in manual and CNC milling machines.

This end mill is appropriate for use in machine shops, maintenance and repair operations, and fabrication environments where a reliable HSS cutting tool is required. The 4-flute configuration is particularly effective for finishing passes and work in harder materials where chip clearance is less of a limiting factor. The Weldon shank design is compatible with standard side-lock end mill holders, reducing pullout risk during aggressive cuts.

Key Features

• High-speed steel (HSS) construction for durability across a broad range of materials
• 4-flute geometry supports finishing cuts and improved surface finish
• Weldon shank provides positive retention in side-lock tool holders
• 5/8 inch cutting diameter for general-purpose milling applications
• 3-3/8 inch overall length suits standard milling setups

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with standard Weldon-shank side-lock end mill holders sized for a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with milling machine tooling procedures. Ensure the milling machine spindle is fully powered down and locked out before changing tooling. Secure the Weldon shank firmly in a properly sized side-lock holder and verify tool runout before initiating a cut. Follow applicable shop safety standards and machine manufacturer guidelines for maximum RPM and depth of cut.
