Manual: 1, Always wear ear, eye, face protection and protective safety gloves. 2, Generally, for rough work, move the burrs across the workpiece counter-rotationally. 3, Pass the tool over the workpiece in the direction of rotation to achieve fine finishes. 4, Min Clamping depth is 2/3 of the shank, if you have to clamp less, pls low speed. 5, If rough running, strong vibrations and increased flying sparks, pls use a new one. 6, Do not apply too much pressure, Let the speed do the work. Smaller burrs require faster speeds. 7, Soft materials, such as aluminum, use a grinding oil to reduce debris clogging. Grind glass, use water as lubricant. 8, Elongate holes, grip tool firmly with two hands and use a swinging motion, which prevents chatter, result in a safer cut. 9, Avoid impact loads, otherwise parts teeth will break off, shank will bend. Do not sink the burr for more than 1/3 of its periphery. 10, Recommendation for drives: shank 1/8" (75 to 300W), shank 1/4" (from 300W), for coarse cuts, 500W+ advantageous.

Works as advertised on mild steel. Quite impressive. Really makes some chips fly. Case is a little cheezy but does its job well enough.

I used the larger cylinder-shaped bit to enlarge some holes with my Kobalt die grinder. It easily cut away the metal, and still looks new afterwards. Great bits at a great price.

I am installing an aluminum radiator in my Camaro and there is a radiator core support bracket that was over-stamped by about 1/8" and interfered with the mounting bracket. I bought these to trim off the excess. Initially, I tried using these in a cordless drill and they barely scratched the bracket. Once I chucked it into my RotoZip, they worked fantastic. In fact, they worked so well that I had to create a little shield to direct the shavings away from my face. I was working in a tight spot and couldn't change the angle to direct the shavings differently or switch the rotation direction. At any rate, these made short work of the task and I couldn't be happier about my purchase. I'll be using these to clean up some Chevy Big Block heads!
