German TIP-TOP tools TIP-TOP models TIP-TOP prices

TIP-TOP tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types. Handheld power tools are more flexible, convenient, and widely used; many varieties have become essential tools for production and daily life. There are numerous power tool brands. According to their function and application, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

TIP-TOP tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope and toggle, saw blade, etc. The two ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the angle of the blade. After tightening the twisted rope, the saw blade is tensioned and ready for use. Frame saws are classified into coarse, medium, and fine types based on blade length and tooth pitch. Coarse saw blades are 650—750mm long, with a tooth pitch of 4—5mm; coarse saws are mainly used for cutting thicker lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting thin lumber or cutting tenons. Fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm; fine saws are mainly used for cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a saw edge and a saw handle, and can be classified into single-sided, double-sided, and backed knife saws. Single-sided knife saws are 350mm long, with teeth on one side; depending on the function of the teeth, they can be divided into rip cuts and cross cuts. Double-sided knife saws are 300mm long, with teeth on both sides; typically, one side is for rip cuts and the other for cross cuts. Backed knife saw plates are 250—300mm long; the back of the backed knife saw is reinforced with a steel strip, the teeth are finer, and they are available as rip or cross cut saws. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade being approximately 200mm long. Groove saws are mainly used for cutting grooves in wood. 4) Panel saw. Also known as a hand saw, it consists of a handle and a saw blade. The blade is approximately 250—750mm long, with a tooth pitch of 3—4mm. Panel saws are mainly used for cutting wider boards. 5) Keyhole saw. The blade is narrow and long, with a pointed tip, and is approximately 300—400mm long. Keyhole saws are mainly used for cutting narrow holes and slots. 6) Coping saw. Also known as a fret saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), and it is mainly used for cutting arcs and curves. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape and stretching a wire between the two ends. Saw-tooth-like projections are cut into the wire, using the sharp edges of these projections for cutting. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for cutting complex curves and opening holes.

TIP-TOP tool usage

1) Select the appropriate saw blade for the workpiece. For example, use 14 teeth per inch for cutting solid or thick soft metals; use 18 teeth per inch for tool steel, iron pipes, and hard metals; and 24 teeth per inch are suitable for cutting metal sheets, metal pipes, and thin iron bars. 2) Push forward to cut, and lift gently when pulling back. 3) Select a wrench of the appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force towards the fixed jaw, never towards the movable jaw. 5) If the wrench jaws are worn or slip during use, do not continue to use them to prevent slipping. 6) Do not use a wrench as a hammer for striking. 5) Do not slide a pipe over the end of the wrench handle to increase torque. 7) Press the inner side of the first leg of the square against the edge of the board, and draw along the inner side of the second leg with a pencil to mark a perpendicular line. 8) Select the appropriate screwdriver according to the size and shape of the screw head slot. 9) Do not strike the screwdriver handle with a hammer; replace damaged handles immediately. 10) Do not use a screwdriver as a chisel or lever. 11) Use an electrician's screwdriver to test current; do not use a standard screwdriver to test high voltage. 12) Do not grind the screwdriver tip to avoid damaging the hardened surface. 13) Do not keep screwdrivers in shirt or trouser pockets to prevent injury from collisions or falls.

TIP-TOP tool operation

1) The single-phase power cord for mobile electric machinery and handheld electric tools must use a three-core flexible rubber cable, and the three-phase power cord must use a four-core rubber cable; during wiring, the cable sheath shall be inserted into the equipment's junction box and secured. 2) Before using electric tools, check the following: no cracks or damage to the housing or handle; correct and secure connection of the protective grounding wire or neutral wire; intact cable or flexible cord; intact plug; normal, flexible, and undamaged switch operation; intact electrical protection devices; intact mechanical guards; and flexible rotating parts. 3) The insulation resistance of electric tools shall be measured regularly using a megohmmeter with 500V. If the insulation resistance between live parts and the housing is less than 2M Ω, maintenance must be performed. 4) After repairing the electrical parts of an electric tool, insulation resistance measurement and dielectric withstand voltage tests must be conducted. The test voltage shall be 380V, and the test duration shall be 1 minutes. 5) Electrical circuits connecting electric machinery and tools shall have separate switches or sockets and be equipped with residual current operated protective devices; the metal housing shall be grounded. It is strictly prohibited to connect multiple devices to a single switch. 6) For current-type residual current protective devices, the rated residual operating current shall not exceed 30mA, and the operating time shall not exceed 0.1 seconds; for voltage-type residual current protective devices, the rated residual operating voltage shall not exceed 36V. 7) The operating switch of motor-driven tools shall be located within easy reach of the operator. During breaks, after work, or in case of sudden power failure during operation, the power supply switch shall be disconnected. 8) When using portable or mobile electric tools, wear insulating gloves or stand on an insulating mat; when moving the tool, do not lift it by the cord or the rotating parts. 9) When using Class III insulated electric tools in damp or acid-containing environments or inside metal containers, reliable insulation measures must be taken and a dedicated supervisor assigned. The switch for the electric tool shall be placed within easy reach of the supervisor. 10) The magnetic surface of a magnetic chuck drill shall be flat, clean, and rust-free. When performing side drilling or overhead drilling, measures shall be taken to prevent the drill body from falling in case of power loss. 11) When using an electric wrench, ensure the reaction torque support is firmly positioned and the nut is securely tightened before starting.
