Makita is known to always consider the research behind the positive features of a good quality tool; they know it has to be light (so it's not too hard to lift!), it has to be reliable (so the tool will always finish the job no matter how difficult or hard it is) and it has to be safe, which is the primary aspect of a tool we always think of first.

Fortunately all these features are part of technology of the Lithium-Ion battery. The facts are self-evident: this battery has a 40% weight saving compared to Ni-Cad or Ni-Mh batteries, it has up to 280% more lifetime working power than Ni-Cad batteries and this battery is also environmentally safe.

The technology behind this advance in battery technology is based on the scientific methods of High Energy. High Energy is based on storing energy to use at timed intervals; the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store a vast mount of Lithium-Ions without causing any deterioration in the in the electrode.

These batteries have very long life cycles; they also have no memory effect unlike Ni-Cad and Ni-MH, which means there is no need to discharge the battery before recharging it.

More and more companies are producing cordless power tools due to the new technology available. Some of the leading cordless power tool brands are Makita, DeWalt, Hitachi and Bosch. Much of the developments surrounding cordless power drill drivers are to do with the battery packs that cordless power tools need to function. As battery pack, technology has improved over the last few years most manufacturers now offer a wide range of battery packs including Li-Ion, Ni-MH and Ni-Cad packs.

There are a lot of types of drill on the market place today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You might chose cordless or electric, when choosing an electric drill there are two voltages, 110 and 240. 110 volt power tools need a power tool transformer and are utilized mainly on building sites, 240 volt tools for home use might be utilized with a RCD circuit breaker for safety. Cordless drill drivers give more flexibility due to the fact that you do not have a mains lead to contend with.

Any tool might feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it might feel like after a few hours of use. While in the shop make sure all controls are convenient, and check to see if the forward/reverse and high/low speed switches in particular are easy to use.

Drilling softwood, hardwood, metal, and masonry all require different drill speeds. Harder materials or larger drill bits have to be worked at lower speed. Conversely, softer materials and smaller drill bits might be utilized at higher speeds. Look for a drill with variable speed. Variable speed allows the user to control the bit speed, indispensable when you plan on working different materials and accessories.

Depending on the choice of material for the anode, cathode, and electrolyte the voltage, capacity, life, and safety of a lithium ion battery might change dramatically. Lithium ion batteries are not to be confused with lithium batteries, the key difference being that lithium batteries are primary batteries containing metallic lithium while lithium-ion batteries are secondary batteries containing an intercalation anode material. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the devices they power. Li-ion batteries are lighter than other equivalent secondary batteries, often much lighter.

Unlike Ni-Cd batteries, lithium-ion batteries might be charged early and often. However, if they are not utilized for a long time, they might be brought to a charge level of around 40% - 60%. Li-ion batteries might be kept cool. Ideally they are stored in a refrigerator. Aging might take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly. Storing a Li-ion battery at the correct temperature and charge makes all the difference in maintaining its storage capacity. It is significantly beneficial to avoid storing a lithium-ion battery at full charge. A Li-ion battery stored at 40% charge might last a lot of times longer than one stored at 100% charge, particularly at higher temperatures.

An electric or portable (battery powered) drill can be a scary thing. But they aren’t hard to use. The most common drill drivers come in a pistol shape, making them easy to hold and use. The drill has a trigger you squeeze in order to make the drill bit turn. Sometimes there is also a safety button located on the pistol handle that has to be pressed at the same time you squeeze the trigger in order to make the drill bit turn. The battery pack is usually inserted into a docking station on the bottom of the pistol handle. Between uses the battery pack is charged in another docking station which is connected to an electrical outlet.

Not all holes need to go all the way through the material. Some holes need only be a certain depth in the wood. The easiest way to make certain you drill the correct depth is to measure the necessary hole depth on your drill bit. Then mark that point on the bit with a marker or wrap some tape around the bit at the measured spot. Then when you drill only insert the drill bit to the mark or tape. You might also purchase bit collars that slide over the bit and are secured at the suitable depth. The collars usually attach with a small hex wrench or screwdriver. The drilling is undertaken and you have to get the bit out. Give the drill a little power to spin the bit and slowly pull it out of the hole. Don’t be too speedy or pull it out without spinning the bit. Either of these may cause the bit to bind in the hole. The hole is complete and now you need to attach the fastener. Bits can be inserted into the drill turning the drill into a screwdriver or wrench. If you are attaching screws determine the size of the screw head and select a matching screwdriver bit. Connect the screwdriver bit to the drill in the same way you would other drill bits. Put the bit head in the screw head and squeeze the trigger. Be careful not to provide so much power that you go all the way through the material (if that’s not called for) or strain the screw head too far down into the material. It’s easy to get carried away with the power of the drill. If you are attaching a bolt fastener you might also purchase bolt sockets that might be attached to the drill. Match the bit size with the bolt, attach the bit to the drill, and screw in the bolt.

Usually referred to as twist drill bits, twist bits are probably the most common drilling tools utilized by the handyman with either a hand or electric drill. The front edges cut the material and the spirals along the length remove the debris from the hole and tend to keep the bit straight. They might be utilized on timber, metal, plastics and similar materials. Most twist drill bits are made from either High Speed Steel (HSS) or Carbon Steel. High Speed Steel drill bits are suitable for drilling most types of material. When drilling metal the HSS stands up to the high temperatures. Carbon steel drill bits are specially ground for drilling wood and might not be utilized for drilling metals as they tend to be more brittle and less flexible than HSS drill bits.

DIY Safety tips:

Although RCDs are a vital safety aid, they can't guarantee 100% protection. Even with them in your home, isn't it better to make a long term investment in good safety practice by looking after appliances such as hedge cutters, hedge trimmers, chainsaws, drill drivers and sanders. Do not work with electricity in damp or wet conditions. If you MUST, always use an RCD. Always place the cable of a hedge trimmer or mower over your shoulder and keep it behind you at all times.
When painting, or using any material that generates toxic fumes or dust, keep the room well ventilated. Never smoke while painting or standing close to a freshly painted area.

Always keep a chemical fire extinguisher in the house. Never use water to put out a fire in an electrical appliance. Gas and electrical work is best left to a registered professional.

RCD's (Residual Current Devices) might respond to changes in the flow of electric current. For example, when a flex or cable is cut or an electric tool malfunctions, and direct contact is made with a mains supply conductor and earth, the RCD automatically disconnecting the power supply to the equipment to reduce the risk of you being electrocuted. RCD's are available as portable adaptors, can be incorporated in plug outlets, as separate stand alone units for fixed wiring installations offering whole house protection or as modular units for use in household consumer units. However, although RCD's are a vital safety aid, they cannot guarantee 100% protection. Even with them in your home, isn't it better to make a long term investment in good safety practice by looking after appliances such as hedge cutters, hedge trimmers, chainsaws, drill drivers and sanders.

If you have any doubts whatsoever about how to safely use any material, or equipment, ask the manufacturer or supplier.
