Questions about this item
How can I confirm the bits are cutting cleanly after installing them in my CNC router?
Run a test cut on scrap wood or acrylic and check for smooth edges without tear-out; the tungsten steel construction should leave a precise finish on materials like plywood, PVC, or resin.
What exactly comes in the package and do I need to buy any collets or holders separately?
The box contains 10 solid carbide two-flute straight bits sized 4X4X28X50; any ER collet or tool holder matching the 4 mm shank must be sourced separately.
Should I choose these 4X4X28X50 bits or a different diameter for fine engraving on acrylic and nylon?
The 4 mm cutting diameter with 28 mm flute length suits detailed engraving on acrylic, nylon, resin, and wood; select a larger diameter only when deeper roughing passes are required.
