German HELLER tools HELLER models HELLER prices

HELLER 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 plane blades and chisels; keeping them sharp ensures ease of use and quality, as the saying goes, "sharpening the axe does not delay the woodchopper." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools are divided by function into multi-function tools (multi-tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engravers); pneumatic tools include polishers and nailers; hand tools are divided into measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

HELLER tool classification

1) Tools: Magnetic properties of materials are often utilized in production to facilitate processes, such as magnetic screwdrivers used in electronics assembly. In machining, large amounts of fine iron chips are generated. These chips flow back with the coolant into recovery containers, often causing circuit blockages and making cleaning difficult. Installing a magnetic oil trough on the machine tool can address this. During metal cutting, coolant containing iron chips flows from the worktable drain into the oil trough. As it passes through the filter screen, the chips are blocked and accumulate on one side due to the ring magnet, while the coolant flows into the oil tank through the oil channel. For cleaning, the oil trough can be easily lifted to dispose of the chips. 2) Molds: When bending and forming workpieces with complex shapes, offset centers of gravity can cause instability if the mold is too small, leading to tipping or warping. For example, adding a positioning magnet to the die cavity can assist in workpiece positioning, reducing mold volume while increasing positioning reliability. 3) Auxiliary tools: In stamping production, steel plates stacked together have no gaps and adhere due to atmospheric pressure, making material handling difficult. Installing a magnetic auxiliary workbench close to the press solves this problem. The principle involves fixing a baffle plate to the workbench with a magnet on one side. The sheet metal to be processed is placed against the other side of the baffle. During operation, vibrations from the press slider movement and punching force cause the sheets to vibrate vertically. The top sheet, unable to overcome the magnetic force due to gravity, leans against the baffle, naturally creating a gap for easy material retrieval. The magnetic force can be adjusted by changing the baffle thickness. Magnetic force acts like an invisible hand to hold the workpiece. By cleverly using magnet technology, we simplify tool structures, improve workpiece process performance, and make production easier, demonstrating that magnetic tools can yield unexpected benefits.

HELLER tool classification

Explosion-proof tools are internationally known as "safety tools" and "non-sparking tools," and domestically as "explosion-proof tools." In China, explosion-proof tools produced, sold, and distributed are classified into two main categories by material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made of copper-based alloys with high-purity electrolytic copper as the base, added with appropriate amounts of aluminum, nickel, manganese, iron, and other metals. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made of copper-based alloys with high-purity electrolytic copper as the base, added with appropriate amounts of beryllium, nickel, and other metals. Both materials exhibit excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly comparable to beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and suitable for strong magnetic field environments. Explosion-proof tools are also classified into two main categories by manufacturing process: 1. Casting process: A traditional manufacturing technique widely used internationally in the 80s and still employed by most domestic explosion-proof tool manufacturers. Advantages of casting include simple process and low manufacturing cost. Disadvantages include lower product density, hardness, tensile strength, and torque, as well as more pores and sand holes, resulting in shorter service life. 2. Forging process: The latest international manufacturing technique, using large presses or punch presses with high-heat-resistant forming molds for one-time forging. Advantages of forging significantly increase product density, hardness, tensile strength, and torque, basically eliminating pores and sand holes, extending the mechanical performance and service life by approximately 1 times compared to traditional casting. Disadvantages include higher investment in equipment and molds, leading to higher costs.

HELLER tool usage

1) Plane blade adjustment: When installing the plane blade, first align it with the cap iron, control the distance between their cutting edges, and then insert it into the plane body. With the edge close to the sole, add the wedge, press down slightly, hold the left corner of the sole with the left hand, and use the thumb to secure the wedge, cap iron, and plane blade. Use a hammer to correct the edge so that it 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 protrusion, lift the plane with the left hand, sole facing up, and sight along it with one eye. If the protrusion is inappropriate, lightly tap the upper end of the blade. If it protrudes too much and needs retraction, lightly tap the rear end of the plane body. If one corner of the edge protrudes, lightly tap the upper side of the same corner of the blade. 2) Planing techniques: When planing, extend the index fingers of both hands forward to press on the plane body, press the rear of the blade with the thumbs, 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 the thumbs and apply slight pressure with the index fingers. Gradually reduce pressure towards the front until no pressure is applied. When retracting, slightly lift the rear of the plane to prevent the edge from dragging on the wood surface, which causes dulling. When planing long stock, place the left foot forward, followed by the right. Before planing long stock, determine whether the surface is heartwood or sapwood. Generally, heartwood is cleaner with clearer grain. If it is heartwood, plane from the root to the tip; if sapwood, plane from the tip to the root. Planing along the grain saves effort. Otherwise, it may cause "tear-out," resulting in a rough, uneven surface and requiring excessive effort. When starting a cut, keep the plane sole firmly on the wood surface; do not lift the front. At the end of the cut, do let the front dip (commonly known as "nodding"). Otherwise, the middle of the planed surface will bulge, a common mistake among beginners that must be corrected.
