Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Corner radius end mill cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity.

Feeds for end mills used in vertical milling machines range from .001 to .002 in. feed per tooth for very small diameter cutters on steel work material to .010 in. feed per tooth for large cutters in aluminum workpieces. Since the cutting speed for mild steel is 90, the RPM for a 3/8" high-speed, two flute end mill is.

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.

What is the cutting time when 100mm workpiece is machined at 1000min -1 with feed = 0.2mm/rev ? (Answer) First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200 (mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5 (min) 0.5×60=30 (sec)The answer is 30 sec.

3. Increased Strength. Just like running up a hill, running on a percent incline on the treadmill is a great way to increase strength. In addition to a 1 or 2% incline, most treadmills can go up to a 10% or 12% gradient. This gradient range is sufficient enough to help you get a great hill workout while on the treadmill.
