Review: Game changer for the amateur woodworker - Not sure whether it's worth paying the premium for the smaller bits that I've bought from this brand, but for this big boy it's well worth the money. Good bit of kit that will grind off pretty much anything - you will then need to put the yards in with 120 grit for sound detailing in hard to reach areas. Lee L - no it doesn't. This is because your wood has excessive moisture content and/or you're being too aggressive with it.
Review: Great bit of kit! - This Kutzall Extreme Burr is efficient and aggressive! . . . Its a great bit of kit in a rotary tool to remove media fast! I use it for carving soft and hardwoods and it is just brilliant! . . . I highly recommend these Kutzall burrs!!
