The Cleveland Powder Metal High-Helix Finishing End Mill, model 539, is designed for high-performance milling applications, specifically in materials requiring a high level of precision and finishing. This mill features a 1/2" (12.70mm) diameter, a cut length of 3.000" (76.20mm), and an overall length of 5.000" (127.00mm), making it suitable for deep cuts and a variety of milling operations.

Made from HSS-E (Powdered Metal) material, it provides superior strength and wear resistance compared to standard HSS tools. The spiral flute type, combined with right-hand spiral and cut, ensures efficient material removal and smooth operation. The high-helix design enhances chip removal, especially in tough or high-speed applications.

With three flutes and a corner radius style, this end mill is ideal for finishing operations in a range of materials, including PM-Plus™ high-performance alloys. The straight shank with a Weldon flat provides a secure grip in the tool holder, making this mill a reliable choice for precision tasks. The bright surface condition adds durability and reduces friction, ensuring a long service life.
