On the table this bit cut several hundred feet of hardwood flawlessly. However, I cut out the bunny part with a table saw for most larger cuts. The bit comes with multiple bearings and has a variety of specified dimensions related to the bearing. Of course you can also use the fence separately for other sizes. 1960 - very large and heavy cutter. While very well balanced I would not recommend using this handheld racquet at any speed. I used it on my 20 year old Makilta 2.1hp router to convert my router table. My router is set to 21,000 RPM. So the torch tip is moving at (6.2 x 21,000) 130,200 inches per minute, which is 7,400 miles per hour. EDIT: 123 km/h. Please note this.
