I had to make a stopped slot 1/4" wide and 1" deep for a pocket to insert the tab at the end of the pegboard . This #45210 Amana bit was the perfect size. I installed it on my router table to make a plunge cut with a start and stop unit to feed the workpiece through the cut. After making a few incremental cuts I was able to cut the grooves for a perfect fit. The drill is very sharp and very well made, high quality at a good price!
