Cordless drills: How to use, how to choose

The new cordless drill/drivers GSR 14,4-2-LI Professional and GSR 18-2-LI Professional from Bosch are the lightest tools in their class. Including the battery, they weigh only 1.3 kg or 1.4 kg respectively. In addition, they are particularly compact, with an overall length of only 196 mm. This makes them ideal for working in tight spaces. The cordless drill/drivers are the perfect fit for your hand, with a super slim handle shape. Bosch has developed this design in response to professional users' interest in lighter, more convenient cordless drill/drivers. The new tools ensure that work can be carried out efficiently and with less effort, even overhead.

Broad range of applications
The motor and new two-speed planetary gearbox with metal gears are designed to allow the cordless drill/drivers handle a broad range of applications. Maximum screw diameters are 7 mm and 8 mm respectively and the maximum drilling diameters are between 25 and 29 mm respectively for wood and up to 10 mm for metal. Joiners can therefore use the tools for nearly all installation jobs in interior fitting work. The new cordless drill/drivers are also the ideal, compact tools for electricians and car mechanics.

Screwdriver bits or drill bits are rapidly clamped and replaced in the single-sleeve 10 mm "Autolock" keyless drill chuck. The drill/drivers have 15 torque settings, so the optimum torque can be selected for any screwdriving application. An LED lamp provides good lighting for the work area. Using the belt clip supplied, professional users can attach the tool comfortably to their belts or to a ladder, for example.

Flexible battery pack system
The energy for the drill/drivers is supplied by a premium lithium-ion battery with a capacity of 1.3 Ah. Thanks to Bosch's unique "Flexible Power System“, the tool can also be operated with a 3.0 Ah premium lithium-ion battery – which comes in handy when a large number of screws is involved. Bosch supplies the cordless drill/drivers with a 45-minute charger as standard. With Bosch's "Hyper-Charge" technology, the batteries are charged to 75 percent after only half of the charge time.


Premium lithium-ion batteries offer long lifetime
The long lifetime of the premium battery is guaranteed by Bosch's Electronic Cell Protection (ECP). It reliably protects the battery against overload, overheating and total discharge. There is no memory effect and the batteries are fully ready for use, even if they have not been used for months.

Two packaging options: carton package and "L-boxx" case
The new cordless drill/drivers GSR 14,4-2-LI Professional and GSR 18-2-LI Professional are available as of September 2009 specialist retail outlets in two types of packaging. With the carton package the recommended retail prices are 179 euros or 199 euros respectively. The "L-boxx" – an extremely robust, stackable carrying case – is a new addition to Bosch. With this option, the recommended retail prices are 199 euros and 219 euros respectively.

Bosch is offering an attractive promotional set to accompany the launch of the new cordless drill/drivers. The set comprises a GSR 14,4-2-LI Professional in the L-boxx, with a second L-boxx containing a 77-piece accessory kit. The recommended retail price for the set is 229 euros. All prices are excluding VAT.

Makita U.S.A., Inc., manufacturer of high quality industrial power tools and accessories and member of the Power Tool Institute (PTI), will adopt the new PTI Torque Procedure to measure torque in cordless power drills, including driver-drills and hammer driver-drills in driver-drill mode. The new test method, agreed upon by all major power tool companies in the Power Tool Institute, is the industry’s first standard to measure torque in drills. Torque is one of the best means to measure the performance of cordless professional drills, a product used by pro tradesmen that accounts for a significant share of all power tool sales.

“Since Makita introduced and commercialized the cordless market nearly 30 years ago, there has been no single standard for measuring torque in cordless drills, and manufacturers have published figures derived from a range of different testing methodologies,” said Stan Rodrigues, Manager, Regulatory and Compliance Department at Makita. “A single standard with a consistent methodology will produce more accurate measurements for comparison, and is a true win for dealers and end-users of driver-drills.”

Prior to PTI’s new standard, power tool manufacturers conducted their own torque measurement in-house or with third party testing labs. The torque numbers were not useful for comparison since the testing hardware and methodologies were not standard. The PTI membership recognized this and worked together to create a new standard.

“Makita supports the new standard,” said Ken Hefley, Makita Senior Vice President, Marketing. “For tradesmen, torque is an important factor in the performance of a drill and a single standard guideline will produce consistent data so professional users can make informed purchasing decisions.”

“Makita is the first to publish torque numbers based on the new PTI Torque Procedure,” added Brad Wheeler, Senior Product Manager for Cordless Products. “Just as Makita is the innovation leader in the cordless category, we are the first to adopt this important standard.”

Makita Corporation is Japan's number one manufacturer and exporter of electric power tools.
In 1958, Makita introduced their first electric tool. In January of that year, Makita began selling portable electric planers, the first such product in Japan.
The company credited its success in the domestic power tool market to high quality construction, pioneering research and development, and a unique system of direct distribution. Instead of relying on wholesalers to market its tools to retailers, Makita employed its own direct sales force. Makita used its comparatively low-cost production base to advantage in Europe and the United States. By the end of the 1970s, the company had captured almost one-fifth of the global professional tool market, nearly matching Black & Decker Corporation's market share. On the product development front, the company introduced the world's first cordless miter saw and also launched a line of 18-volt cordless power tools during 1999. Among the new products debuting the following year was a circular saw with an attached dust collector and also the world's first line of cordless tools powered by nickel-metal hydride batteries. The latter were more environmentally friendly than the previously ubiquitous nickel-cadmium batteries, which contained cadmium, a heavy metal. By this time, the company had developed a recycling program that enabled customers to return their used batteries--both types--to any retailer within Makita's huge worldwide network.
Today Makita is one of the world's largest power tool manufacturers with seven manufacturing facilities globally and a selection of over 350 superior, innovative tools and well over 4,500 accessories.
Makita continues to set the standard for quality, reliability and performance by manufacturing innovative power tools. More informations about Makita you can find here, also you can visit official site of Makita Corp.

Electric brake is drill feature which helps you to stop the spinning bit.
Once you stop holding the power trigger the braking will start so the drill stops rapidly permitting you to put the drill down more safely, otherwise you run off time when waiting for the spinning bit to stop before you can put it down. Before electric brake system masses became impatient and place the drill down while it was spinning down and this was an unsafe practice and was the case of injuries where the spinning bit got caught on the cable and cause electrocution or caught something else which spun the drill causing the bit your enter the persons arm or hand causing physical damage.

- R. E. DeWALT

The original company was started in 1924 by Raymond E. DeWalt, the inventor of the radial arm saw. The company grew quickly and was reorganized in 1947, manufacturing radial arm saws and other stationary woodworking machines. After buying the company in 1949, American Machine & Foundry Co. Inc. sold it to Black & Decker in 1960. Black & Decker divested itself of the radial arm saw manufacturing branch in 1989, selling it to two executives. Radial arm saws that use the original DeWalt design can still be obtained from the Original Saw Co.

In 1992, Black & Decker started a major effort to rebrand its professional quality and high-end power tools to DeWalt.

In 1994, DeWalt took over the German high end wood working power tool producer ELU. DeWalt enlarged their assortment of cordless tools and other tools using ELU's technology. DeWalt has maintained this focus on high-end branding, and consistenly is identified as the most preferred brand of commercial tools in recent surveys of commercial contractors

Today the DeWALT Power Tools line consists of over 200 electric power tools and over 800 accessories including: drills and hammer drills; screwdrivers; circular, chop, miter, table, reciprocating, and jig saws; planers; impact wrenches; die, angle, and bench grinders; shears; nibblers; sanders; laminate trimmers; routers, and plate joiners.
