Cobalt steel ball end mills with two milling ends. with better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as cast iron, hardened steel, titanium, and tool steel. when one end wears out, turn the tool around for a sharp edge.

Cutting down the centerline will slap an insert or flute flat against the edge of the material, which creates burrs and generally makes it hard to get great surface finish. instead of a 50/50 cut down the centerline, choose about 70/30 for a better result. tram your mill carefully, or put it out of tram intentionally.

Cutting tool materials: high speed steel (hss) provides good wear resistance and costs less than cobalt or carbide end mills. hss is used for general-purpose milling of both ferrous and nonferrous materials. vanadium high speed steel (hsse) is made of high speed steel, carbon, vanadium carbide and other alloys designed to increase abrasive wear resistance and toughness.

this finishing ball end mill provides high precision and long tool life in profiling operations. the insert’s carbide substrate provides a superior balance of wear resistance and anti-chipping properties, while the spiral edge form and unique coatings enable this tool to finish mill at high speeds in a wide range of work materials.

Milling troubleshooting tips about vibration issues, chip jamming, re-cutting of chips, unsatisfactory surface finish, burr formation, machine power and tool wear are presented in the following table. select a positive and light-cutting cutter and insert. try up milling. check spindle deflection to see if it is acceptable for the machine.

this process enables shops to drill holes and water lines in a block, perform heat treatment, and then apply the high-speed strategies to rough and finish in one setup. metal removal rates are high, and semi-finish and finish operations are minimized, because the hard-milling process results in near-net-shape parts.

i have some ball end mills that i hardly ever use. on the other hand, a corner radius is useful any time there is a potential to create a stress riser at a sharp corner, or merely for appearance because sometimes the blended corner just looks better. also, as i mentioned the corner radius seems to make the end mill much more rugged and .
