摘要： A portable cutting device having a cutting tool for cutting a material. The cutting device includes a motor driving the cutting tool and a shroud at least partially enclosing the cutting tool. The shroud defines a debris accumulation chamber for gathering debris created by the cutting tool cutting the material. An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag.

摘要： A powered vinyl groover includes a motor attached to a circular blade and a blade housing for covering the circular blade. The blade housing includes a duct to carry cuttings into a collection bag. Near an inlet hole of the duct is a fin, which may be a raised surface on any interior wall of the blade housing extending into the blade housing as close as possible to the blade. The fin causes airflow from the blade to be redirected towards the inlet hole of the duct so that more cuttings enter the duct and are carried by the duct through to an outlet hole to a collection bag mountable over the outlet hole of the duct. The fin may be integral with the blade housing or attached to it, and a fin may also be added to existing groovers.

摘要： It is, accordingly, an object of the present invention to provide a technique which is effective in preventing chips generated during cutting operation on a workpiece from being accumulated in a region ahead in a cutting direction. A representative cutting machine includes a motor, a blade, a body housing having a first region that houses the motor and a second region that covers the blade and projects forward of a front surface of the first region, a base, an angular plate, an outlet formed in the body housing, an opening and a blocking part. The blocking part prevents the air discharged from the outlet from flowing out laterally with respect to the moving direction of the base through a clearance between a front end of the second region and the one end of the angular plate and thereby helps the air discharged from the outlet flow into the opening.

摘要： A self-contained vacuum circular saw is presented. The vacuum saw has a casing around the saw blade that includes an accordion type lower section attached to the lower platform of the saw. A number of vacuum tubes, preferably four, are attached to the side of the circular saw opposite the blade. The armature of the circular saw that turns the blade also turns the vacuum impeller on the side opposite the blade. An impeller vacuum chamber pulls in the dust and debris created by the saw blade and discharges the dust and debris into a disposable and removable vacuum bag. An important aspect of this device is that the motor that turns the saw blade also turns the impeller, thus making the self-contained vacuum Saw moveable from site to site.

摘要： A movable handle and a power tool. The power tool comprises a housing, a motor supported by the housing and operable to drive a tool element about an axis, and a handle supported by the housing for rotation relative to the housing about the axis. Preferably, the power tool is a circular saw. The circular saw further comprises a switch assembly supported on the handle for movement with the handle and means for connecting the switch to the motor to accommodate movement of the switch relative to the motor. The switch assembly is electrically connectable to the motor and selectively connects the motor to a power source, and the connecting means includes a wiring arrangement. The circular saw further comprises a locking assembly for locking the handle in a position relative to the housing. Also, the circular saw preferably comprises means for preventing the switch assembly from connecting the motor to the power source when the locking assembly is in the unlocked condition and means for preventing the locking assembly from being operated from the locked condition to the unlocked condition when the switch assembly is in the operated condition.

摘要： A metal cutting circular saw is provided with an upper blade guard which includes a first sight window disposed in a first side surface and disposed in a plane angularly offset from a plane of the blade. The upper blade guard also includes a second sight window disposed in the second side surface of the upper blade guard. A light window is disposed in a front portion of the perimeter outer surface of the upper blade guard. The upper blade guard is made from metal and the first and second sight windows and the light window are integrally formed as a one-piece member. The saw shoe and lower blade guard are configured to minimize chip spray from contacting a user.

摘要： A power tool including a housing for an electric motor and a mounting for a disc having a housing, wherein the motor is arranged to drive the saw blade about its axis. The housing includes at least one guard member covering a peripheral portion of said disc and a debris conduit allowing removal of debris from the disc during use in a first cutting mode. A removable member is attachable to the housing to selectively block the debris conduit such that the tool can be used in a second cutting mode.
