I end up using paddle bits a lot during rough-ins when an auger-drill isn't available or would just be too inconvenient to use. All the use dulls bits in a heartbeat and a new paddle-bit might only last me about five days.
Can these things be sharpened effectively?
I've been looking into using different types of bits, ones that have a circular blade seem like they might work better: more cutting area = longer life? But a lot of these bits seem designed for precision wood work, not use and abuse with framing lumber.
Am I stuck constantly shelling out for new paddle bits or does anyone know an alternative?
