Woodworking machinery needs to be chosen very wisely. This is because while wood is hard, it is also a very fragile material to deal with. Cutting it the wrong way will not be correctable and it might lead to much material wastage. You must therefore get tools that cut with precision in order to advance in the trade. This is how you increase productivity and curb wastage.
The brief history just serves to illustrate the development of the drill and close on the heels of the drill were many other corded and cordless power tools. Mains powered devices operate on a variety of voltages 120v in the US and in Europe we operate on two voltages. We have 220-240v powered tools normally used in the home and for the less demanding applications whereas in the construction arena health and safety demands 110v units powered by 220-240v to 110v transformers. Battery powered tools use different battery types and operate at different voltages. The power screwdriver is the least demanding of the electrically operated tools in the power toolbox and may be supplied with as little as 3.6v batteries. The capability of the batteries has increased year by year as we have seen battery technology move gently from 9.6v to 36v such that we now have tools supplied with batteries rated at 12v, 14.4v, 18v, 24v and 36v. Needless to say the 36v tools are much more expensive than the 12v tools. The development in battery technology has been considerably more than just building larger battery packs. The latest batteries are Lithium-ion or Li-Ion batteries which enable more battery power to be delivered and batteries can be quickly recharged.
Having a mere enthusiasm might jack you up for a trade. However, it will definitely ruin your prospects of being deemed as a master of it. A power tool might seem to be an easy to operate machine, however, it is a mixed bag of complexities that only a certified technician can understand and, relate to.
Other considerations when choosing the appropriate tool to use include the power source and the speed specification. Different tools use different power sources such as electricity, battery or fuel and hence the proper tool should be selected depending on the available power source. Different machines operate at different speeds depending on the work they are designed to perform for example a combination hammer has a high speed that delivers a high impact force and is ideal for chiseling or drilling in hard concrete walls.
With the advent of these higher voltage batteries we now have a wider range of battery powered cordless tools. The cordless circular saw was not viable before the 18v or possibly the 24v batteries became available. The SDS drill and demolition drill had always been corded until the latest range of batteries mean there are now SDS and demolition cordless drills on the market operated on 36v power packs.
