2016.11.28 - Boat Building Tip No. 2
Always remove the drill bit from the drill when you are finished using it to drill the current hole especially if the bit size is less that 1/4" or 6mm. Double that bit size if you are working more than 2m or 6' off the ground.
Failure to do this means that when (not if) you knock the drill on to the workshop floor, you will break the bit which will turn out to be the last one in your toolbox and the ironmonger is now closed so you cannot get another one until tomorrow.
