Abstract:
An electric boring tool comprises an electric motor, a switch trigger, a tip tool driven by driving force of the electric motor, a power transmission mechanism for transmitting the driving force of the electric motor to the tip tool as rotational force and/or hammer force, and a motor control unit for controlling speed of the electric motor in response to an extent of pulling of the switch trigger. The motor control unit subjects the electric motor to low speed control after the electric motor is started up, and controls the speed of the electric motor in response to the extent of pulling of the switch trigger when the load current of the electric motor is set value or greater during the low speed control.
Abstract:
A clutch brake removal tool configured to facilitate the removal of a single piece clutch brake from an input shaft. The clutch brake removal tool includes a rectangular shaped body having a plurality of walls forming a hollow interior volume. The body includes a first sidewall and a second sidewall and further includes a first end and a second end. The body has an opening at the second end providing access to the interior volume. The second end of the body has a leading edge wherein the leading edge is formed in a semicircular shaft so as to mateably abut against an input shaft. The first sidewall includes a first slot formed therein wherein the second end of the first slot is contiguous with the opening of the body. The second sidewall includes a second slot formed identical to the first slot and located on the opposing sidewall.
Abstract:
A siding hammer having a depth control face spaced in front of a striking face of a hammer head of the hammer. The depth control face strikes a substrate into which a fastener is being driven when the fastener has been driven to a predetermined depth of penetration in the substrate to inhibit the fastener from being driven further into the substrate. In certain embodiments, the depth control face is removable to permit the hammer to be used without depth of penetration control. In certain embodiments, the depth control face is adjustable to adjustably control fastener depth penetration. Attachments are also provided for temporarily converting a hammer into a siding hammer.
Abstract:
A depth gauge for use with a drill bit includes a body configured to receive a drill bit, a retention mechanism coupled to the body and configured to removably couple the body to the drill bit, and a cap configured to be removably coupled to the body. The cap can be coupled to the body in one of a first position relative to the body where the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a first depth, and a second position relative to the body where the cap contacts the workpiece surface to prevent the drill bit from entering the workpiece more than a second depth that is different from the first depth.
Abstract:
A power tool (1) for driving a working tool (3) that penetrates at least axially into a to-be-machined material (2), and including a signal processor (6, 6′), and a transducer (5) which is suitable for exciting and detecting a high-frequency electromagnetic wave (4) propagating axially along the working tool (3) and which is connected to the signal processor (6, 6′) that is designed to determine the penetration depth (T) of the working tool (3) into the material (2) based on high-frequency electromagnetic waves (4).

Abstract:
A drill bit has a shank portion having a plurality of SDS-type slots, a cutting portion comprising at least one cutting flute, and an intermediate portion connecting the shank to the cutting portion, the intermediate portion including at least one additional slot. A depth gauge includes a body configured to receive the drill bit, a retention mechanism coupled to the body and having an inward projection to removably couple the body to the at least one additional slot in the drill bit, and a cap coupled to the body such that the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a predetermined depth, wherein the cap is movable relative to the body among a plurality of positions, wherein each of the plurality of positions corresponds to a different predetermined drilling depth.
Abstract:
A stake driver for driving wood stakes into a soil has a rectangular hollow housing having an open top and an open bottom. The bottom portion is configured for receiving at least a part of the wood stake therein, while an elongated driving shaft extends from an interior of the housing upwardly above a top edge of the housing. The upper part of the driving shaft is configured for engagement by a power transmitting tool, such as for instance a jack hammer. A driving pad is secured to a bottom end of the driving shaft transversely to the longitudinal axis of the housing. At least one hammer plate is secured, through connection to a shaft sleeve, to the driving shaft above the driving pad. The hammer plate and the driving pad are each configured to move in an axial direction inside the housing and transmit a hammering force to the wood stake. The hammering force is partially absorbed by a compression spring positioned between the hammer plate and the driving pad.
