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.

i am a 66 year old woman and was able to use my drill and this tool to grind out bigger latch holes in two steel screen doors so they would latch after they had sifted out of alignment.

I purchased this item to adapt a new door handle on a garage access door, which has a metal sheet on one side.I needed to enlarge the hole and it was perfect for that.

Worked good for what we needed it for, and lasted for an entire job. Better quality than stuff from harbor freight.

This is a brief review, because I have not used other burr sets, and don't know how to compare.It looks and feels like quality.I used it with an electric drill in large fir beams. 2nd stage cleanup after hogging out rotted pockets with a Forstner drill bit.Very helpful.
