Abstract: A mortiser has a housing mounted on a support post and there is a collet on the housing for holding a mortise chisel. A chisel drive coupling is on the housing. A chisel drive shaft extends through the housing and connects with the chisel drive coupling. A reciprocal engagement mechanism is capable of selectively engaging the chisel drive coupling. An operating lever may thus be quickly indexed so that the mortise chisel may be filly lowered without the user pulling the operating lever fully toward him/her and downward. The mortiser also has a finely adjustable ram fence and a depth stop. The collet has a notched or elliptical bore to prevent jamming of the chisel shank in the collet.

Abstract: A brad point drill bit having a boring tip defined by at least a pair of peripheral cutting members and a center blade disposed therebetween. The center blade is formed with a protruding central cutting edge for engaging a workpiece. The center blade also has two concave lateral cutting edges radially extending from the central cutting edge and rotationally offset therefrom. The peripheral cutting members comprise spurs having two cutting edges and pointed in a clockwise rotational direction of the drill bit.
