German WIDIA tools WIDIA model WIDIA price

WIDIA tools refer to electrical safety tools, which are various specialized tools and devices designed to prevent accidents such as electric shock, burns, falls, and stumbling, thereby ensuring the personal safety of workers. In power systems, to complete tasks smoothly without causing personal injury, operators must carry and use various safety tools. For example, electrical safety tools are required when inspecting operating electrical equipment, changing operating modes, or performing maintenance and tests; climbing safety tools are needed during line construction; when working on live electrical equipment or in areas near live equipment, insulated safety tools must be used to prevent electric shock or arc burns. Electrical safety tools can be divided into four categories: personal protective equipment, insulated safety tools, climbing tools, and warning signs.

WIDIA tool classification

1) Electric planer: It is one of the main tools used in woodworking and decoration. It is mainly used for planing flat and straight surfaces of various woods. Products are divided into short planers and rough planers. Rough planers are mainly used for planing flat wood surfaces and can process larger board surfaces; short planers, in addition to planing board surfaces, can also be used with various guides to plane tongues and grooves, borders, and slots. The main features of using a handheld electric planer are small size, light weight, portability, and ease of use. Compared with manual tools, it can greatly reduce labor intensity and improve processing efficiency and quality. When using a handheld electric planer, hold the handle at the rear of the planer body with your right hand and slightly raise the center of gravity of the rear part. After starting the power with your left hand, hold the guide handle at the front of the planer, keeping the front center of gravity lower. Follow the operation sequence where the front of the planer contacts the wood first. When the rear center of gravity gradually and steadily contacts the planing surface, push the planer forward smoothly in the direction of planing with both hands. After the planer body completes the planing stroke, lift the front of the planer with your left hand, then pick it up with both hands and return to the starting point for the next pass. Repeat this until all planing is completed. 2) Jigsaw: Also known as electric coping saw, electric fine saw, etc. It is a multifunctional cutting tool that can cut materials from wooden boards, as well as perform straight or curved cuts on plastic and metal sheets. It is particularly suitable for cutting complex shapes and geometric figures with small radii of curvature. It is an essential multifunctional sawing tool for home renovation and various public interior decoration projects. It features light weight, small size, portability, simple operation, and wide application range. Its cutting principle involves a narrow saw blade with teeth facing upward. During operation, the blade moves in a linear reciprocating motion up and down to cut, completing various sawing tasks according to size requirements. If used with a guide plate, it can also perform angled bevel processing. When using an electric jigsaw, for smaller and thinner wooden boards, fix them on a workbench first and support the workpiece with your left hand. Then, hold the saw handle with your right hand and push forward slowly for sawing. Apply steady and uniform force; do not exert excessive force to avoid injuring yourself or damaging the blade. For larger boards, ensure the board is securely fixed, then hold the saw handle with both hands and push forward for sawing. Follow the marked line during sawing and always keep the blade perpendicular to the board surface to prevent jamming or binding. 3) Circular saw: Also known as a small handheld circular saw. It is a new type of small handheld electric saw equipped with a spring-loaded automatic safety guard and an electronically controlled constant-speed motor. It features simple operation, flexible use, quick adjustment, and high safety and reliability. It is very suitable for home renovation tasks such as cutting various wooden boards and fiberboards. The thickness of wood or boards being cut should generally be 60mm or less. 4) Sanding tools: Also known as small handheld grinders. They are mainly used for sanding bare wood before painting various wood finishes, and can also be used for sanding putty coatings. However, sanding putty generates significant dust, which seriously pollutes the environment, so enhanced labor protection is required during operation. Handheld grinders include belt sanders and orbital sanders. Belt sanders are mainly used for rapid sanding of wooden components and products, while orbital sanders are commonly used for sanding larger areas such as wooden floors in home renovations. 5) Small engraving machine: Also known as a slotter or trimmer. It can be used for slotting, tenoning, drilling, trimming, milling, and edge finishing on various wooden products and components. It can also be used for simple trimming, milling, grooving, and edge finishing on light metal materials such as aluminum alloy and plastic steel, such as aluminum alloy (or plastic steel) doors and windows, balcony frames, and furniture frames. Therefore, it is also one of the commonly used power tools in modern home renovation projects.

WIDIA tool structure and composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; transverse arrangement is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic lines of force are evenly distributed on the disk surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same contact area; the point of action of the magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

WIDIA tool usage

1) Explosion-proof tools provide safety assurance for workers in flammable, explosive, and corrosive workplaces, making our society safer and allowing our staff to work with greater peace of mind. After daily use, explosion-proof tools require proper maintenance, which is crucial for their service life. Improper maintenance may prevent the tools from serving us for a long time. First, store the tools in a dry place to prevent damage to working parts. In daily work, after continuous striking 20 times, treat the attachments on the tool surface, wipe clean, and then reuse. Do not use continuously, as prolonged friction may cause the tool to overheat, potentially damaging the product. 2) After use, wipe off surface dirt and deposits, and store in a dry, safe place. 3) Striking tools must not be struck continuously. After more than ten strikes, allow appropriate intervals, and promptly remove debris adhering to the product before continuing use. 4) Wrenches must not be used with excessive force. Do not use sleeves or bind other metal rods to extend the lever arm, nor use a hammer to tighten fasteners (except for strike wrenches). 5) Cutting-edge tools should be gently touched against a grinding wheel in a water trough for sharpening. Do not apply excessive force or maintain contact with the grinding wheel for too long. 6) In actual operation of striking and chiseling tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum-copper alloys are more suitable for normal pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots). Beryllium-copper alloy explosion-proof tools are suitable for applications such as refineries, gas transfer stations, gas extraction plants, and drilling teams. 7) Remove surface oil stains before using various products, and use according to the instructions for steel tools.
