Precision Twist Drill 5110014 Hss End Mill 4 Flute 5/8 in

Product Description

The PRECISION TWIST DRILL 5110014 is a high-speed steel (HSS) end mill with a Weldon shank and four flutes, designed for milling operations requiring reliable cutting performance in a range of materials. The 5/8-inch tip diameter and 3-3/4-inch overall length make it a practical choice for standard milling applications in metalworking environments. HSS construction provides the toughness needed for interrupted cuts and general-purpose work. This end mill is installed and used by machinists, tool-and-die workers, and maintenance trades operating vertical milling machines and machining centers.

This end mill suits residential and light industrial machine shops, maintenance facilities, and production environments where consistent metal removal is required. The four-flute configuration delivers a smoother finish compared to two-flute designs, making it appropriate for finishing passes on ferrous and non-ferrous metals. The Weldon shank style is a widely accepted standard for end mill holders, providing positive anti-pullout engagement during operation.

Key Features

• High-speed steel (HSS) construction for toughness across a range of materials
• Four-flute design for improved surface finish on finishing passes
• Weldon shank for positive retention in standard end mill holders
• 5/8-inch tip diameter for common milling applications
• 3-3/4-inch overall length for standard reach requirements

Compatibility

Designed for use in standard end mill holders that accept Weldon shank tooling. Confirm holder bore size matches the 5/8-inch shank diameter before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the milling machine spindle is fully de-energized and locked out before changing tooling. Seat the Weldon shank fully into the holder and tighten the set screw against the flat to prevent pullout during cutting. Inspect the end mill for chips or cracks before each use and replace if any damage is found.
