Abstract: A cutting tool in which a disc-like cutter blade is fixed to a spindle of a rotary electric tool, comprising a first guide plate, which is attached on electric tool side to a cutter blade such that it is capable of rotating freely and makes contact with the reference surface of a cutting object material on a process of cutting progress so as to guide along a cutting direction, an inner flange located between the first guide plate and the cutter blade so as to specify a distance X from the reference surface of the cutting object material to a cut groove and a second guide plate which is provided on an opposite side to the electric tool side of the cutter blade and makes contact with a cut face of the cutting object material on a process of the cutting progress so as to stop moving in the cutting direction to specify a cut groove depth Y.

Abstract: A constant angular grinding tool comprising: a profile wheel whose grinding face is fixed at an inclination angle with respect to the axis of a spindle of a rotary electric tool; a first guide plate which is a disc member attached rotatably to a spindle between the profile wheel and the rotary electric tool so as to guide for a grinding direction by bringing the edge of the disc member into a contact with the reference level of a material; and a second guide plate which is a disc member attached rotatably to a spindle between the profile wheel and the first guide plate and whose outer peripheral end face makes contact with the edge of the material to control a grinding distance from the edge.

Abstract: A pair of profile wheels 14, 18 in which concavely shaped grinding surfaces 141, 181 asymmetrical to each other are opposed to each other at right angle so as to form a concavely shaped grinding surface having a substantially semi-circular section, a guide plate 13 which is mounted on a spindle 11 of an electric or air tool side of the profile wheel 14 freely rotatably for guiding a grinding direction by bringing the edge of the circular shaped member into contact with a reference face of a grinding object material and a stopper ring 16 which is mounted to a spindle between the pair of the profile wheels 14 and 18 freely rotatably for controlling a grinding distance Y from the edge by bringing its outer peripheral end face 161 into contact with the edge of the grinding object material, are fixed to the spindle 11 with a lock nut such that they are set at right angle to the spindle.
