20.0 mm ball nose end mill
The M.A. Ford 16578740 Tuffcut GP is a 4 flute ball nose end mill with a 20.0 mm diameter. It is designed for general-purpose milling in a variety of materials using CNC machinery. The stub length provides increased rigidity for shallow pocketing and profiling operations. This new accessory suits machinists and fabricators requiring precise contouring capability.
Installation and common issues
The tool mounts directly into a compatible tool holder or collet sized for the 20.0 mm shank. Secure clamping is essential to prevent runout or tool pull-out during high-speed rotation. Vibration and premature wear typically indicate excessive overhang or incorrect feed rates for the material. Users must observe the California Proposition 65 warning regarding exposure to listed chemicals during handling and machining.
Practical limits of the interface
The fixed 20.0 mm diameter determines the minimum internal radius achievable in a workpiece corner. The stub length restricts the maximum axial depth of cut to shallow applications only. The 4 flute design limits chip evacuation capacity compared to fewer flutes, affecting performance in deep slots or sticky materials. Tool life and finish quality depend heavily on matching speed and feed to the specific workpiece material.

Questions about this item
How can I confirm the 20.0 mm Tuffcut GP 4 flute ball nose end mill is cutting correctly after installation?
The tool should produce a smooth ball-nose profile without chatter, and the 4 flute design should leave a clean finish on the workpiece when run at the proper feed and speed for the material.
What is included with the M.A. Ford 16578740 end mill and what must be purchased separately?
The package contains the 20.0 mm stub-length ball nose end mill only; a compatible tool holder, collet or pneumatic spindle, and personal protective equipment are not included and must be sourced separately.
Which version of the Tuffcut GP 4 flute ball nose stub end mill should I select for a 20.0 mm cutting diameter?
Choose the model identified by part number 16578740, which is the 20.0 mm diameter stub-length variant in the Tuffcut GP 4 flute ball nose series.
