Precision Twist Drill 5110368 Hss End Mill 2 Flute 0.25 in

Product Description

The PRECISION TWIST DRILL 5110368 is a high-speed steel (HSS) end mill designed for material removal in milling operations across a range of industrial and trade applications. Featuring a Weldon shank for positive tool retention and a 2-flute geometry, this end mill delivers clean cutting action with efficient chip evacuation. The cutting diameter measures 0.25 inches and the overall length is 3.375 inches. HSS construction provides the toughness needed for interrupted cuts and general-purpose milling where carbide tooling is not required. Machinists and tooling professionals reach for this style of end mill when slotting, profiling, or peripheral milling in steel, aluminum, and similar materials.

This end mill suits manual mills, CNC machining centers, and drill press setups where a Weldon flat shank is preferred for secure chuck or collet engagement. The 2-flute design is particularly effective in softer metals and non-ferrous materials where chip clearance is a priority. It is sold individually and is appropriate for job shops, maintenance operations, and production environments requiring a reliable general-purpose HSS cutting tool.

Key Features

• High-speed steel (HSS) construction for toughness and re-sharpenability
• Weldon shank design provides positive engagement and prevents tool pullout
• 2-flute geometry promotes efficient chip evacuation during slotting and profiling
• 0.25 inch cutting diameter suits common milling applications
• 3.375 inch overall length offers reach for standard depth-of-cut requirements

Compatibility

Designed as a general-purpose HSS end mill compatible with milling machines and machining centers equipped with Weldon-style tool holders or set-screw collet chucks sized for a 0.25 inch shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the Weldon flat against the set screw in the tool holder to the holder manufacturer's specification before starting the spindle. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.
