The Sedgwick 571 Hollow Chisel Morticer features a cast iron base, column, table, and slideways, which provide a rigid and durable mainframe assembly onto which to mount the cast iron chisel head and motor. The head itself is counterbalanced by a weight, giving fingertip control to the rise and fall and eliminating the breakages associated with spring type mechanisms. Its 1.1Kw industrial fan cooled motor provides ample power for continuous duties and is fitted with a fully guarded ½” capacity adjustable chuck. Unlike a collet type system the chuck holds the auger firmly round its circumference, true to the centre line of the chisel, securing longer tool life and better cutting capability.
The table has longitudinal and lateral movement on a single handwheel, not only for ease of operation, but also for more precise positioning: lateral adjustment of the table being better controlled by a central screw. The angled timber clamp is adjustable on a tee slot, giving a maximum timber width of 200mm. Coupled with the height adjustable chisel head which can give a maximum timber height of 255mm underneath the chisel, the Sedgwick 571 has exceptional capability. For repetition work there are longitudinal stops along the front of the table, a marking out rail complete with turnover stop along the rear; and 2 position depth stop for haunching.
The switchgear has no volt release, thermal overload protection, and a mushroom headed stop button.
