Grinder Converted To Right Angle Drill FARM SHOP Miscellaneous Mike Toppen Allegan Mich tapped the back side of an old Jacobs drill press chuck with 5/8-11 thread allowing him to also use his DeWalt cordless angle grinder as a right angle drill “By using the angle grinder with the threaded chuck and a drill bit I can use one piece of equipment to do 2 different jobs ” says Toppen who works for a mobile repair business “I carry my tools with me in my pickup and the fewer tools I have to carry around the better ” he says Toppen found the 1/2-in drill press chuck in a box of junk that he bought cheap at a sale He used a lathe to bore a tapered hole into the back of the chuck and then tapped it with a 5/8-11 thread - the same thread found on the cordless angle grinder Toppen says he’s surprised that DeWalt doesn’t make an adaptor chuck designed to convert an angle grinder drill to a right angle drill “Maybe it’s because angle grinders don’t operate with as much torque and the rpm’s are higher limiting you to bits with higher cutting speeds “For example a DeWalt 4 1/2-in angle grinder like mine is designed to operate at 5 700 rpm’s whereas large drill bits are designed to operate at a lower cutting speed with more torque But my right angle drill conversion is still a handy tool for just drilling a hole through something in close quarters where a drill won’t fit ” Contact: FARM SHOW Followup Mike Toppen 3889 1/2 127th Ave Allegan Mich 49010 ph 269 673-5597; mike@toppentech com
