20 mm ball-nose end mill

The M.A. Ford Tuffcut GP 15078740 is a 20.0 mm diameter, two-flute ball-nose end mill built for general-purpose milling. It suits machinists and maintenance teams cutting contour profiles, radii and 3-D surfaces in steel, cast iron and non-ferrous alloys. The tool is supplied new and ships directly from the manufacturer.

Two-flute geometry

The two-flute design is the single specification that determines chip clearance and finish quality; it provides wider gullets for faster chip evacuation in softer materials but leaves a slightly rougher surface than higher-flute alternatives. Buyers who need finer finishes or tighter tolerances on hardened steels should select a different flute count.

Standard shank fit

The cutter uses a standard shank that fits common ER collets, Weldon holders and shrink-fit systems, so no special adapters are required. The most common installation issue is insufficient clamping force, which allows the tool to pull out under heavy radial loads; always verify holder torque and run-out before cutting.

Questions about this item

What material can the 20.0 mm ball nose mill cut in a real machine?

The 20.0 mm ball nose end mill is designed for general-purpose milling across a range of materials including steel, cast iron and non-ferrous alloys.

What shank standard does the 15078740 end mill use and what does that limit?

The cutter uses a standard cylindrical shank that fits common ER collets and Weldon holders, limiting use to machines with matching tool-holding systems.

What physical clearance does the 20.0 mm diameter tool need to fit in a fixture?

The 20.0 mm cutting diameter requires at least 20.0 mm of open bore or slot width plus shank clearance for the holder and collet nut.
