Precision Twist Drill 5110017 Hss End Mill 6 Flute 5/8 in

Product Description

The PRECISION TWIST DRILL 5110017 is a high-speed steel end mill with a Weldon shank, designed for precision material removal in milling operations. It features 6 flutes and a 5/8 inch cutting diameter, delivering smooth chip evacuation and a consistent finish across a range of metals and alloys. Weighing 0.4 pounds, this end mill is built for durability under repeated use in production and job-shop environments. Machinists and tool-and-die professionals rely on this type of tooling for slotting, profiling, and peripheral milling where accurate cuts and tool stability are required.

This end mill is suited for general-purpose milling of ferrous and non-ferrous metals in both manual and CNC machining setups. The Weldon shank design provides positive drive engagement, reducing the risk of tool slippage under heavy cutting loads. It is appropriate for use in vertical mills, knee mills, and machining centers where a 5/8 inch shank collet or end mill holder is available. The 6-flute geometry makes it particularly effective for finishing passes where surface quality is a priority.

Key Features

• High-speed steel (HSS) construction for durability across a range of work materials
• 6-flute design supports smooth chip flow and improved surface finish
• Weldon shank provides positive drive and resists pullout under load
• 5/8 inch cutting diameter for mid-range milling applications
• Sold individually, minimum order quantity of one

Compatibility

Designed for use in milling machines and machining centers equipped with a 5/8 inch end mill holder or Weldon-style collet system.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully powered down and locked out before loading or removing tooling. Secure the end mill in a properly sized Weldon-style holder, tightening the set screw against the flat on the shank to the holder manufacturer's specification. Inspect the cutting edges for damage before each use and replace if chipping or wear is observed.
