German ARCTIC tools ARCTIC models ARCTIC prices

ARCTIC tools, also known as hand tools, are distinguished from power tools. They primarily rely on manual force to turn or apply pressure. Hand tools are categorized by use into wrenches, pliers, screwdrivers, tape measures, hammers, sockets, cutting tools, scissors, tool sets, and auxiliary items such as tool carts, with each category having different models. Wrenches include open-end wrenches (fixed wrenches), double box-end wrenches, ratchet wrenches (quick wrenches), combination wrenches, pipe wrenches, T type socket wrenches, cross socket wrenches, adjustable wrenches, etc.; pliers include wire cutters, needle-nose pliers, diagonal cutters, snap-ring pliers, slip-joint pliers, water pump pliers, pipe wrenches, locking pliers, etc.; screwdrivers include slotted, Phillips, Pozidriv, hex, and Torx types; sockets are divided into standard sockets, Torx sockets (E type sockets), driver sockets (BIT sockets), spark plug sockets, impact sockets, etc. Common specifications include 1/4", 3/8", and 1/2", where " denotes inches; each specification is further divided into 6-point sockets and 12-point sockets; hammers include claw hammers, machinist hammers, ball-peen hammers, rubber mallets, and installation hammers; cutting tools include files, diamond files, tin snips, aviation snips, utility knives, square tube saws, pipe cutters, bolt cutters, etc. Materials include chrome vanadium steel, carbon steel, and alloy steel.

ARCTIC tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, making them suitable for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups connect a vacuum pump to the suction cup via an electromagnetic control valve. When the control valve evacuates air, negative pressure forms in the cup cavity to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction is lost, releasing the workpiece. The suction force of vacuum pump suction cups mainly depends on the adsorption area of the suction cup and the vacuum degree inside the cup (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and offers strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping: The structure of a straight-bar dual-cylinder translational gripper involves fingers mounted on a straight bar with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move inward to clamp the workpiece; when no pressurized gas enters, springs push the two pistons outward to release the workpiece. A flow divider valve is installed in the cylinder intake line to ensure synchronous piston movement. This type of end effector is used in loading and unloading assembly workstations.

ARCTIC tool usage

1) Rip cutting method: When sawing, place the wood on a bench, step on it with your right foot perpendicular to the cut line, stand straight with your left foot at a 60° angle to the cut line, keep your right hand perpendicular to your right knee, and position your body at approximately a 45° angle to the cut line. Lean forward slightly and move naturally, avoiding leaning left or lunging right. Hold the saw with your right hand and place your left thumb against the blade for positioning. Gently pull and push the saw a few times (pull first, then push) to start the kerf, then remove your left hand from the edge. When the teeth have cut about 5mm into the wood, use your left hand to assist your right hand in lifting and pushing the frame saw. Lift lightly, raising the saw hand slightly; push heavily, applying force with your wrist, elbow, shoulder, and waist rhythmically. This ensures the saw blade follows the cut line. Otherwise, the edge of the rip-cut wood will be curved or uneven, or the kerf face will be inconsistent. 2) Crosscutting method: When sawing, place the wood on a bench, stand to the left rear of the wood, hold the wood with your left hand, hold the saw with your right hand, and step on the wood with your left foot. The sawing method is the same as for rip cutting. When using a frame saw for crosscutting, the lower end of the blade should tilt forward. For rip sawing, the upper end of the blade tilts backward at an angle of about 75°—90° (angle with the wood surface); for crosscutting, the blade tilts backward at an angle of about 30°—45°. Always ensure the blade follows the line without deviation. The kerf must be straight; avoid swaying the blade left and right, which causes skewing. When the wood is nearly severed, stabilize the cutoff piece with your left hand, slow down the sawing speed, and cut completely through. Do not leave any material to break off or snap by hand, as this can damage the blade and cause the wood to split along the grain, affecting quality.

1) Plane blade adjustment: When installing the plane blade, first fit it properly with the cap iron, controlling the distance between their cutting edges, then insert it into the plane body. Bring the cutting edge close to the sole, add the wedge, and press down slightly. Hold the left corner of the sole with your left hand, using your thumb to secure the wedge, cap iron, and plane blade. Use a hammer to adjust the blade so that the cutting edge protrudes from the mouth. The amount of protrusion is proportional to the cutting depth: more for rough planing, less for fine planing. To check the blade protrusion, lift the plane with your left hand, sole facing up, and look back with one eye to detect it. If the protrusion is inappropriate, tap the upper end of the blade lightly. If it protrudes too much and needs retraction, tap the tail of the plane body lightly. If one corner of the cutting edge protrudes, simply tap the upper side of the same corner of the blade. 2) Planing points: When planing, extend the index fingers of both hands forward to press on the plane body, press the thumbs on the rear of the plane blade, and grip the handle tightly with the remaining fingers and palms. Keep the plane body level and apply uniform force with both hands. When pushing forward, increase force with both thumbs and apply slight pressure with the index fingers. As you reach the front end, gradually reduce pressure until none is applied. When retracting, lift the rear of the plane slightly to prevent the blade from dragging on the wood surface, which can dull it. When planing long stock, step forward with your left foot, followed by your right. Before planing long stock, check whether the surface is heartwood or sapwood; generally, heartwood is cleaner and has clearer grain than sapwood. If it is heartwood, plane from the root to the tip; if it is sapwood, plane from the tip to the root. Planing along the wood grain is less laborious. Otherwise, it is easy to "chatter," resulting in a rough, uneven surface and excessive effort. When starting a cut, keep the plane sole tight against the wood surface; do not lift the front of the plane. At the end of the cut, do not let the front of the plane dip (commonly known as "nodding"). Otherwise, the middle part of the planed surface will bulge unevenly, a common mistake among beginners that must be corrected.
