A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver chuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use.
A leaf blower, commonly known as a blower, is a device that propels air out of a nozzle to move debris such as leaves and grass cuttings. Leaf blowers are powered by electric or gasoline motors. Gasoline models have traditionally been two-stroke engines, but four-stroke engines were recently introduced to partially address air pollution concerns. Leaf blowers are typically self-contained handheld units, or backpack mounted units with a handheld wand. The latter is more ergonomic for prolonged use. Larger units may rest on wheels and even use a motor for propulsion. These are sometimes called "walk-behind leaf blowers" because they must be pushed by hand to be operated. Some units called blower vacs, can also suck in leaves and small twigs via a vacuum, and shred them into a bag.
A Woodworking machine is a machine that is intended to process wood. These machines are usually powered by electric motors and are used extensively in woodworking. Sometimes grinding machines are also considered a part of woodworking machinery.
A jackhammer is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. It was invented by William McReavy, who then sold the patent to Charles Brady King. Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete.
Dremel is a multinational brand of power tools, focusing on home improvement and hobby applications. Dremel is known primarily for its rotary tools, such as the Dremel 3000, 4000 and 8200 series, which are similar to the pneumatic die grinders used in the metalworking industry by tool or moldmakers. Dremel later expanded its product range and now produces butane tools, benchtop and hand-held saws and oscillating tools. The company was purchased by Robert Bosch GmbH in 1993, and is now a division of the Robert Bosch Tool Corporation.
An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding and polishing. Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.
Sawdust is a by-product or waste product of woodworking operations such as sawing, sanding, milling and routing. It is composed of very small chips of wood. These operations can be performed by woodworking machinery, portable power tools or by use of hand tools. In some manufacturing industries it can be a significant fire hazard and source of occupational dust exposure.
A pneumatic motor, or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is supplied by either a vane type air motor, piston air motor, air turbine or gear type motor.
Renovation is the process of improving broken, damaged, or outdated structures. Renovations are typically done on either commercial or residential buildings. Additionally, renovation can refer to making something new, or bringing something back to life and can apply in social contexts. For example, a community can be renovated if it is strengthened and revived. It can also be restoring something to a former better state. Renovation is very common in some places. For example, there are more than twenty thousand home improvement projects every year in Hong Kong, affecting more than a million residents.
A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to handhold it or fix it to a workbench. Woodworking sanders are usually powered electrically, and those used in auto-body repair work are usually powered by compressed air. There are many different types of sanders for different purposes. Multipurpose power tools and electric drills may have sander attachments.
Milwaukee Electric Tool Corporation, known more commonly as Milwaukee Tool, is a multi-national company that develops, manufactures, and markets power tools, hand tools, tool accessories, tool storage, and personal protective equipment. Milwaukee Tool was last sold in 2005 for $626.6 million to the Hong Kong–based Techtronic Industries, also known as TTI Group. The company is now a subsidiary of TTI Group alongside brands like AEG, Ryobi, Hoover, Dirt Devil, and Vax. In 2022, $206 million was invested in Wisconsin research and development facilities.
SKIL Power Tools is a brand of electric power tools and accessories located in Naperville, Illinois, United States. It is a subsidiary of Chervon (HK) Ltd, a company based in Nanjing, China.
Makita Corporation is a Japanese manufacturer of power tools. Founded on March 21, 1915, it is based in Anjō, Japan and operates factories in Brazil, China, Japan, Mexico, Romania, the United Kingdom, Germany, United Arab Emirates, Thailand, Indonesia, Malaysia, Philippines, Canada, and the United States. Annual sales were equivalent to $3.1 billion in 2012.
Air pollution in Hong Kong is considered a serious problem. In 2004, visibility was less than eight kilometers for 30 per cent of the year. Cases of asthma and bronchial infections have soared due to reduced air quality. However, in recent years, the hours of reduced visibility in Hong Kong have decreased by significant amounts compared to the previous ten years.
A concrete grinder is an abrasive machine for grinding and polishing concrete and natural stone. Concrete grinders can come in many configurations, the most common being a hand-held general purpose angle grinder, but it may be a specialized tool for countertops or floors. Angle grinders are small and mobile, and allow one to work on harder to reach areas and perform more precise work.
An oscillating multi-tool or oscillating saw is a multitool and power tool that oscillates, powered by battery or mains. The name "multi-tool" is a reference to the many functions that this tool can perform with the range of attachments available. "Master Tool" is also a trade name used in North America, short for the original tool by Fein called the Multi-Master. Attachments are available for sawing, sanding, rasping, grinding, scraping, cutting, and polishing.
Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in the contaminated air.
Makita Auto-Start Wireless System, Festool Autostart (2018‒) and Bosch Wireless Auto-Start (2024‒) are Bluetooth-based systems for remotely starting industrial vacuum cleaners from power tools. Several power tools, cordless battery packs, and industrial vacuum cleaners ship with wireless connectivity, mostly using Bluetooth Low Energy to communicate, but as of 2024 the systems remained incompatible between different brands.
Any type of woodworking that involves cutting, either by hand or machine, releases sawdust. Because fine sawdust can float through the air, it can be easily inhaled without proper protection, leading to damaging injuries to a woodworker's skin and lungs. Sawdust is also an IARC group 1 Carcinogen.
Nemo Power Tools is the first manufacturer of a full line of power tools that are pressurized to work under water for boating, scuba and other deep sea activities. The company also uses the same technology to manufacture a clean room drill and a special ops line of underwater tools. The company was founded by Nimo Rotem and Oleg Zhukov.
