A cutting tool such as jigsaw generally comprises a main body, a plunger provided for the main body to be reciprocally movable in an axial direction thereof, the plunger being provided with an opening and a cutout axially formed to a portion opposing to the opening, a cutting blade to be mounted to the plunger, and a blade mounting mechanism for mounting the blade to the plunger. The blade mounting mechanism comprises a support member inserted into the opening of the plunger and provided with an engaging groove formed along a direction of mounting the blade, a ring member disposed to outer peripheral surfaces of the support member and the plunger, the ring member being formed with a tapered portion at an inner peripheral surface thereof opposing to the cutout of the plunger, and an elastic member for urging the ring member in a direction that a diameter of the tapered portion of the ring member reduces, thereby fastening the blade by the tapered portion of the ring member and the engaging groove of the support member.

A drill press assembly having a base mountable to a work bench, a vertical column attached to the base and a drill head assembly having an electric motor and a quill. The drill head assembly is movably attached to the column. A rack is rotatably attached to the top of the column and is engaged by a crank and pinion mechanism attached to the frame of the drill head assembly which permits the drill head assembly to be displaced vertically and rotated about the column. A tilt table is attachable to the base of the drill press. A locking mechanism having a bolt passing through a longitudinal slot in the supporting base of the tilt table and a transverse slot in the base is engaged by an eccentrically mounted camshaft to lock the supporting base of the tilt table to the top surface of the drill press base. A pivoting frame is pivotably attached to the supporting base and contains a table plate. A fence is attachable to the top of the pivoting frame. The fence has a stopping block to facilitate the location of a workpiece on the tilt table. A work clamp is also provided on the drill head assembly to clamp a workpiece on the tilt table.

A cut waste discharging device for a circular saw blade of an electric power circular saw machine, which includes: a safety cover for covering an upper portion of the circular saw blade; a lower guard which is angularly movable into the safety cover in accordance with development of a cutting operation of a workpiece with the circular saw blade; and a partition wall provided along an inner peripheral wall of the safety cover so as not to interfere with the lower guard, thereby defining a passage of cut waste with the outer wall of the partition wall and the inner peripheral wall of the safety cover. With such an arrangement, the passage between the outer wall of the partition and the inner wall of the safety cover causes the cut waste, generated in the waste generating portion, to be led to a predetermined discharge place. Accordingly, the waste would not be splash within the safety cover and would not be splashed out of the predetermined discharge place.

A table saw has a circular saw table, a miter table and a supplementary table to form a working table, on the front and rear sides of which two guide rails are disposed slidably with respect to the working table. The miter table has a miter fence thereon whose pivot points are provided at two separate positions.

Table saw

An automatic planning machine for cutting a surface of a workpiece which includes: a base portion on which the workpiece is to be laid; a feeding device for feeding the workpiece; a rotatable cutter block arranged on one side of the base portion with a rotary shaft substantially in a vertical direction; and a reference base disposed vertically on the other side of the base portion; wherein an upper side of a workpiece feeding path between the reference base and the cutter block is opened. A height of the reference base is lower than that of the cutter block and a top surface of the reference base is held horizontally. The automatic planning machine may comprise an auxiliary reference base which is detachably mountable on a top surface or a side wall of the reference base. The planning machine may further comprise a planing reference base disposed on a side of the cutter block, wherein the feeding device includes rotatable roller members each of which has a rotary axis substantially in a vertical direction, and spring members for pressing the workpiece, and a pressing device disposed in the reference base facing the planing reference base, for generating selectively a pressure which is larger than a pressure of the spring members of the roller members and a pressure which is smaller than the pressure of the spring members of the roller members to press the workpiece.

Automatic planing machine

An automatic planing machine has two feed rollers on one side of the machine and a stool for holding two pressure rollers which are pressed toward the feed rollers with a pressure force smaller than a pressure force of the feed rollers. The machine has a compact driving mechanism for rotating the feed rollers and further has a feed mechanism for move the stool and a casing for holding the feed rollers toward and away from each together with back-lash preventing means.

An automatic planning machine has a vertical stationary stool functioning to cut a workpiece flatly and a vertical movable stool opposed to the stationary stool. The stationary stool has a plurality of feed rollers while the movable stool has a plurality of pressure rollers. A pressure force by the pressure rollers can be selectively changed over thereby to push the workpiece on the stationary stool at the time of flat work and to push the workpiece on the movable stool at the time of thickness determination work.
