Grinder Converted To Right Angle Drill

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
