Loosen and remove the Allen screw with the provided Allen key. Try inserting a sharp pointed object such as a small nail into hole for Allen screw. Use point on nail to push broken drill bit towards countersink side of tool. Once broken bit is removed insert new drill bit and secure with Allen screw that was previously removed.
PLUG CUTTERS ARE OUT THERE 7/16 IS A HARD FIND THERE USED FOR PLUGS OF THE SAME WOOD YOUR WORKING ON IF THATS NOT IT BUY A 7/16 DOWEL AT HD JOE
I use it for wood. I personally don't think it would work on very well on steel. Not the type of countersink I use on metal work.
It is also 1/8''.
The bits are sized for #6, #8, #10 and #12 screws. I'm afraid they don't go to 1/2" if that's what you're after, but Ryobi does make two countersink bits with the same quickload shank as these. They come in 5/8 and 3/4" diameters, either one could do a 1/2" countersink just fine.
6, 8, 10 and 12.
Thank you for asking, Barracudas. Not all bits are sold as individuals. Please check at Home Depot for any available bits. I hope this helps and we appreciate your interest in Ryobi! -Keri
The largest countersink in the set is #12 and the cutting diameter is .430 so it will not cut a 1/2 inch diameter hole.
yes Dave look into the tool aria. if you still cant find the right size order it on line. you should get a home depot account.
Remember folks when cutting metal. A little dark cutting oil goes a long way to keep the heat under control and saving the cutting edge of the bit. Alu is a soft metal, lube up!
