Ball end mills create a round-bottomed groove in a workpiece. Square end mills cut a flat-bottomed groove with 90° inside corners. Corner-rounding end mills create a rounded outside edge on a workpiece. Drill mills have a nose with a pointed tip that can drill holes or create angled features in a workpiece.

CALL US AT (716) 462-4349 Don't Fear High Speed Hard Metal RobbJack CorporationChoosing the proper cutting tool is very important when machining hardened metal. There are three basic designs of cutters:ball end, corner radius (bullnose) or square end (Figure 1). The first choice in hard metal machining should be the ball end mill. The ball end mill should be used for roughing operations and most finishing operations.

Details. ALH Mill End Mills:For Aluminum and Non Feeds and Speeds for .250" Ball end Mill in 4140Mar 11, 2013 · With such a small cut on a ball nose tool the diameter were it is cutting is MUCH smaller than the tool. Assuming your going nose down into the part rather than tilting off angle. Carbide in 4140 needs significantly more speed that 100SFM. Even if this is pre-hardened 4140, 300SFM would be reasonable.

Oct 01, 2015 · A key to tool life and part quality in milling, and especially in high-speed milling of hardened steels, is maintaining constant chip load on the milling tools cutting edges. Chip load equals the feed rate divided by the spindle speed multiplied by the number of cutting flutes, and chip load that varies widely or is too low or too high will Mitsubishi Materials Web Catalogue|Solid End Mills2 flute long neck ball nose end mill for high-speed machining of hardened steel. Short shank type suitable for use with a shrink fit holder. Solid Carbide Requirements for milling hardened steelsDec 02, 2011 · In general, hard milling involves cutting primarily tool steel or precipitation hardening stainless steel, such as 15-5 or 17-4, that has been hardened to at least 50 HRC. After a workpiece is roughed in the soft state, it is sent to the furnace for hardening and then finish machined with coated carbide, ceramic or PCBN tools.
