If you've never used taps before,just take it easy with them, they're very hard steel but also very brittle...If you try to cut the thread all in one go you stand the chance of snapping the tap in half whilst still in the hole...very annoying..and a bugger to get out...
Make sure to get the tap aligned perfectly..its very easy to tap a thread at a slight angle...Just screw the tap in half a turn ,then back it off slightly to clear the swarf from the threads..then screw in another half turn and back off again and so on until you've finished cutting all the thread........
Apologies for the advice if you know what you're doing....
