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.
I love these Nibbler carving bits. They absolutely unleash the power of the humble Dremel. You don't need a die grinder (which to some people can be intimidating) to do some decent carving. They remove a good amount of wood almost effortlessly and one never gets the feel that you are a knifes edge away from injuring yourself! I like the T shape cutter as it gives more texture to the carving.
I recently bought a Bonsai Nibbler, T-maxi but was not sure whether it would fit on my Ryobi dremmel. I contacted Terry at Bonsai Tree that guided me through the process in understanding the specs and made the decision to buy easy. The product has been a great addition to my endeavor in my bonsai journey. My experience of the purchase, time spend information on and the product itself was and still is excellent. I will in future definitely buy from Bonsai Tree. Thank you Terry. Please keep up with what you are doing. Wim Hollander
