With the Ahead Drill Bit you can easily transform your (electric) screwdriver into a super drum tool.
Insert the Ahead Drill Bit in your screwdriver's chuck and you have created a speedy monster of a drum key!
If you need to change all of your drum heads, you can save a lot of time by using this tool.
Put the drill bit in your screwdriver, put it in "reverse" - and off you go!
It is worth noting that you must exert caution when using a drill bit. You do not have the same feeling of how far down you have screwed the tension rod as when you use a regular drum key. Therefore, be careful, because it may go wrong if you use max power.
If you drive the tension rod down too quickly you risk destroying the drum head and in the worst case also your drum's lugs. Therefore, be careful and only use screwdrivers that have a nice speed control.
