Product Identity
The YINGHUA two-flute straight-slot end mill is a tungsten-steel cutter sized 4x4x28x50 for CNC engraving and cutting. It targets workshops and hobbyists machining acrylic, PVC, nylon, resin, wood and plywood.
Installation Notes
The shank fits standard collets matching the 4 mm diameter, so mounting is a simple collet change. The main risk is running the tool above the spindle speed recommended for the material, which causes premature flute wear or breakage.
Practical Limits
Two flutes limit chip evacuation in deep slots, so axial depth per pass must stay conservative in dense woods or plastics. The cutter is not suited for metals or abrasive composites, and the 18-year age restriction applies to all operators.
