Bosch Carbide-Tipped Lock Mortising Bits are micrograin bits that work with lock mortisers using 1/4-in - 28 thread. They can be mounted directly on the spindle shaft of the Bosch 1604LM or Porter-Cable 513.
Bosch micrograin bits cut fast for mortises when work is started at the edge and provide a smooth finish cut that is ideal for surfacing operations. Useful when good chip clearance is important, especially in gummy wood.
