Find a grinder that spins at 7-8,000rpm and this tool will perform superbly. I've been carving green oak with it for 2 months and I love it!
TOP CLASS TOOL WHICH REMOVES MUCH OF THE HARD WORK INVOLVED IN SHAPING.
I'm a sculptor making sculptures of very hard oak from old wine vats. For me Roto rasp is an excellent tool, save me hours of cleaning, sanding, and shaping. I couldn't work without it anymore! Delivery from England to France no problem. Highly recommend though a bit expensive for a poor artist!
My wife and I are in the process of finishing a home that was started 32 years ago. The house is of post and beam construction. It was framed but never enclosed. I am working on well seasoned Douglas Fir Beams. They are tight knot old growth, somewhat harder than new growth Douglas Fir lumber. The medium grade roto rasp disc is great for removing the gray weathered exterior of the beams making them look like new again.
Excellent tool, really wish I'd bought it earlier as it would have saved me a fortune on sanding discs
…Roto Rasp is a cost effective alternative. Made from nitrated steel, it resembles a cheese grater, and is available in fine, medium and coarse. It fits 115 mm angle grinders and is solid as a sanding solution, particularly for paint removal, so it comes down to a balance between finish and speed of stock removal.
That said, you can easily use it for the sort of shaping you might otherwise use a sintered “doughnut” disc or coarse abrasives. It is very easy to control.
