Shane; that is the reason I bought this notcher.It would take hours to do those notches by hand w/a grinder or belt sander.I have all ready done that type of work w/my awesome TN-250.I got the extra deep hole saws & only have to cut the slug in half once on those super deep notches.I couldn't be w/o my TN-250 now.The best $550.00 dollars I have spent in the shop in year's.Scott Mock
