Precision Twist Drill 5110019 Hss End Mill 6 Flute 1 in

Product Description

The PRECISION TWIST DRILL 5110019 is a high-speed steel (HSS) end mill designed for material removal, profiling, and milling operations across a wide range of machining applications. Built with a 6-flute configuration, this end mill delivers a higher feed rate and improved surface finish compared to lower-flute-count tools, making it well suited for finishing passes on ferrous and non-ferrous materials. The Weldon shank provides a secure, slip-resistant connection in the tool holder. With a 1-inch cutting diameter and an overall length of 4 inches, this tool fits standard vertical and horizontal milling setups used by machinists and tool-and-die professionals.

This end mill is intended for use in production and job-shop milling environments where consistent tool life and reliable performance are required. It is appropriate for cutting steel, cast iron, aluminum, and similar workpiece materials when used within the speed and feed parameters appropriate for HSS tooling. The Weldon shank style is compatible with standard side-lock tool holders commonly found on manual and CNC milling machines.

Key Features

• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 6-flute design supports higher feed rates and improved surface finish on finishing operations
• Weldon shank provides a positive, slip-resistant grip in side-lock tool holders
• 1-inch cutting diameter suitable for standard milling and profiling cuts
• 4-inch overall length accommodates typical workpiece depths in vertical milling setups
• Sold individually (each), with a minimum order quantity of 1

Compatibility

Designed for use with standard side-lock Weldon shank tool holders on manual and CNC milling machines that accept a 1-inch shank end mill.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine powered down and locked out per applicable OSHA lockout/tagout procedures. Secure the Weldon shank firmly in a properly sized side-lock holder using the appropriate hex key to engage the flat on the shank. Inspect the tool for visible damage before use and do not exceed the speed and feed parameters recommended for HSS end mills and the workpiece material being cut.
