They will work if the tap broke due to a side way break (opperator error) but if it breaks because of pressure and is tight in the hole you might have a 25% chance of getting the broken tap out. The best way to avoid a broken tap is to only thread about one turn then back out the tap then go another turn when hand tapping.
