Extremely sharp window output. The drill and chisel work well to install as directed. I've easily made hundreds of cut slots in solid maple with the 1/2 set. I wouldn't recommend doing large projects with small hand chisels in hardwood to any real depth with a 1/2 inch set. Too much to be removed with a hand lever. However, with a good mortiser these make great chisel sets/bit don't waste your money on cheaper sets.
