Abstract
A rotary chisel blade (2) for connection with a hand held rotary power tool. The chisel blade (2) includes a resilient disc (4) having a plurality of gullets (6) for removing waste formed in the periphery (8) of the disc (4). A tooth (10) having a cutting edge (12) is fixed to each gullet (6). An arcuate portion (14) of the cutting edge (12) is formed on a corner of the each tooth. Each tooth (10) is provided with a first flat face (16) which is perpendicular to the plane of rotation of the blade (2) and is inclined forward of a radius (R) of the disc (4) in the direction of rotation. A second flat face (18) is contiguous with and extends from the first flat face (16) in a direction away from the periphery (8). The cutting edge (12) extends along the edge of the first and second flat faces (16, 18).
