Harima Japanese Pattern Mortice Chisel & Bit 1/2" Imperial (510285)
Auger bit with a point on the end, one cutting spur and a single spiral for rapid chip clearance
Easy to sharpen single spur and the bits cut evenly and fast
Will easily handle all timbers and will improve your machine
The design of the Japanese pattern could well reflect the use of softer timbers used in traditional Japanese furniture making, the auger having a deep, high ratio flute, quickly removing the longer slivers softwoods create. The auger bit on this type has a point on the end, one cutting spur and a single spiral for rapid chip clearance. The single spur is easy to sharpen and the bits cut evenly and fast, even in the hardest of timbers.
Either way, a high quality chisel will enhance your morticer's performance to a degree where once tried you will never use a low quality chisel again.
N.B. As all the auger bits have to accommodate different machines they are supplied long and will need cutting with a conventional hacksaw blade to suit the specific machine for which purchased.
