German V-COIL tools V-COIL models V-COIL prices

V-COIL tools refer to implements used in woodworking. They generally have sharp cutting edges, so safety must be prioritized during use. Frequent sharpening is required, especially for planer blades and chisels; keeping them sharp ensures ease of use and quality, as the saying goes, "sharpening the axe does not delay the woodcutting." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools are divided by function into multi-function tools (such as multi-purpose oscillating tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engravers); pneumatic tools include polishers and nailers; hand tools include measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

V-COIL tool classification

1) Electric planer: One of the main tools used in woodworking and renovation. It is primarily used for planing flat and straight surfaces of various woods. Products are available as short planers and roughing planers. Roughing planers are mainly used for planing flat wood surfaces and can process larger board surfaces; short planers are used for board surface planing and can be combined with various guides to plane tongues and grooves, edges, and slots. The main features of handheld electric planers are small size, light weight, portability, and ease of use. Compared with hand tools, they significantly reduce labor intensity and improve processing efficiency and quality. When using a handheld electric planer, hold the rear handle with your right hand and slightly raise the rear center of gravity. After starting the power with your left hand, grip the front guide handle, lower the front center of gravity, and ensure the front of the planer contacts the wood first. As the rear center of gravity steadily contacts the planing surface, push the planer forward smoothly in the direction of planing with both hands. After completing the planing stroke, lift the front of the planer with your left hand, then lift it with both hands to return to the starting point for the next pass, repeating until the planing is complete. 2) Jigsaw: Also known as electric saber saws or electric fine saws. It is a multi-function cutting tool that can cut wood panels, 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 multi-function sawing tool for home renovation and various public interior decoration projects, featuring light weight, small size, portability, simple operation, and wide application range. Its cutting principle involves a narrow saw blade with upward-facing teeth that performs a vertical reciprocating motion to cut according to size requirements. When used with a guide, it can also perform angled bevel cuts. When using an electric jigsaw, fix smaller and thinner wooden boards to a workbench and support the workpiece with your left hand, then hold the saw handle with your right hand and push forward slowly. Apply steady and uniform force; do not exert excessive force to avoid injury or damaging the blade. For larger boards, ensure the board is securely fixed, then hold the saw handle with both hands and push forward. Follow the marked line during cutting and always keep the blade perpendicular to the board surface to prevent binding or jamming. 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, flexibility, quick adjustment, and safety, making it suitable for home renovation tasks such as cutting various wood panels and fiberboards. The thickness of wood or boards being cut should generally be 60mm or less. 4) Sanding tools: Also known as small handheld polishers. They are mainly used for sanding bare wood before painting various wood finishes, and can also be used for sanding putty surfaces. However, sanding putty generates significant dust, which seriously pollutes the environment, so enhanced personal protective equipment is required during operation. Handheld polishers 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 large areas such as wooden floors in home renovations. 5) Small engraver: Also known as a router or trimmer. It can be used to cut slots, tenons, holes, edges, mill, and trim various wood products and components. It can also perform simple edge cutting, milling, grooving, and trimming 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.

V-COIL tool classification

Non-sparking tools are internationally known as "safety tools" and "non-sparking tools," and domestically in China as "explosion-proof tools." Explosion-proof tools produced, sold, and distributed in China are divided into two main categories based on material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools. The specific material is a copper-based alloy composed of high-purity electrolytic copper as the base, with added aluminum, nickel, manganese, iron, and other metals. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools. The specific material is a copper-based alloy composed of high-purity electrolytic copper as the base, with added beryllium, nickel, and other metals. Both materials have excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are comparable to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools are also divided into two main categories based on manufacturing process: 1. Casting process: A traditional manufacturing process that was the international standard for explosion-proof tool production in the 80s and is still widely used by most domestic manufacturers. Advantages of the casting process: simple process and low manufacturing cost. Disadvantages: lower product density, hardness, tensile strength, and torque resistance; more pores and sand holes, resulting in shorter service life. 2. Forging process: The latest international manufacturing process, which uses large presses or punch machines with high-heat-resistant forming molds to forge products in a single step. Advantages of the forging process: significantly improves product density, hardness, tensile strength, and torque resistance; basically eliminates pores and sand holes, extending the mechanical performance and service life of products by approximately 1 times compared to traditional casting processes. Disadvantages: higher investment in equipment and molds, resulting in higher costs.

V-COIL tool maintenance

1) Setting: The set of the saw teeth is adjusted using a saw set. When setting, engage the slot of the saw set with the saw teeth and apply force to bend them left or right. The degree of set must meet the required specifications. 2) Filing: When filing saw teeth, clamp the saw blade in a vise so that the teeth are exposed. Depending on the size of the teeth, use a triangular steel file 100 to 200 mm in length. File each tooth from right to left, applying uniform force with both hands. Keep one face of the file vertically against the lower edge of the tooth and the other face against the upper edge of the adjacent tooth. If the set of the teeth is disordered, place the saw blade flat on a steel plate and use a wooden mallet to flatten all the teeth, then reset and refil them. Additionally, maintain the saw frame; if damage is found in the rope, nuts, knobs, or wooden joints, adjust or repair them promptly.
