To adapt your power drill to the function of mortar raking, you must first remove any drill bits from the chuck. Depending on the type of drill you have, you may need to use a different method to release the drill bits.
Step 1 – Open chuck jaws
Raise the drill slightly so that the mortar rake will not fall out and open the jaws of the chuck
Step 2 – Insert mortar rake
Place the mortar rake in the chuck, shank-end first.
Step 3 – Close chuck jaws
Turn the chuck to close the jaws around the mortar rake’s shank.
