Bonsai Nibbler, R-maxi

4 reviews


  • Currently for use ONLY in a Dremel brand tool.
  • CNC machined from a single piece of T431 high-tensile stainless steel
  • 3 Micrograin Tungsten carbide cutting tips
  • Maximum 20 000 rpm
  • Complete with solid support collet, tips, screws and screwdriver
  • Spare R-tips can be ordered here.


The three tungsten carbide cutting tips in this Nibbler are indexable and replaceable. When the edges are blunt you simply unscrew the tips and turn them to a fresh edge. The tips are normally used in the metal-cutting industry to cut stainless steel so they will last exceptionally long when cutting wood.

This Nibbler screws directly onto the threaded spindle of a Dremel. This gives it vastly superior rigidity and reach over a standard collet mounted tool. Its super rigidity gives very smooth and precise handling for deep, heavy roughing cuts and also for fine finishing cuts.

All Nibblers are made from T431 grade stainless steel, which has nearly double the tensile strength of 304 grade stainless steel.


  • 4.5mm neck diameter
  • 16mm head diameter
  • 55mm overall length

      Bonsai Nibbler

      It is a new tool to me. I will need to practice working with it. It is effective and sharp. You need a strong steady hand to control it

      Nibbler bits

      The quality of these bits is incredible. They remove wood at an alarming rate for such a small bit. Run very smooth and are very easy to use. Also able to do fine work with these bits. So glad I have one now in my box of tricks.
