subject: Choosing The Right Blade For The Right Job [print this page] Saw blades play an important role in the job related to wood working.The proper type and the use of the blades also determine the level of finesse the worker can command.In all the major lumber jobs,there are four categories of blades that are used frequently in various kinds of saws.The categories are determined on the basis of the features and functions that the blades do have.
The main function of the saw blade is to cut the wood and that too in a proper manner without spoiling the effect and the texture.Therefore it is necessary that the blades should be sharp and should have a non-corrosive touch so as not to get spoiled by the different elements present.
But before you decide upon a saw blade,there are certain things which need to be considered.It is always a good idea to be choosy when you want to buy a blade.After all it is this component of the saw which is going to cut your wood and give it the required shape and size.Any individual who has some basic knowledge about the various kinds of saw blades available in the market can do a bit of research and arrive at a logical conclusion.
There is no dearth of saws and their blades in the market depending on the quality and performance preferred by the customer.There is,in fact,an abundance of blades some of which are really cheap and some which fall in the costlier category.
It is generally said that the number of teeth on the blade determine the finesse and quality of the cutting work.It has been found that if the blade has more number of teeth then the results are much better as compared to the blades which have lesser number of teeth. Blades are used to cut various objects,both metallic and non-metallic.And the strength of the blade is determined by the material that it is made up of.
There are generally four types of blades which are in popular use:
Rip Blade - A rip blade really does just that - rip apart the log that is being cut.A rip blade has a lesser number of teeth but takes lesser time to cut.On the downside,it doesn't have a very clean finish.
Cross Cut Blade - Such kind of blades are used to cut all types of woods across the grains.The blade moves and cuts in alternate moves as its teeth are located in an alternate manner.The teeth cut into one direction first and then into the other side.It gives out a finished cut while moving.
Combination Blade - It is a fine mixture of both the rip and the cross cut blade.This kind of blade is in widespread use.The blade can consist of a minimum of 24 teeth or a maximum of 80 teeth.The main premise being the number of teeth determines the quality of cut.
Carbide Tipped Blade - These kinds of blades are more toughened and durable.They have a longer life and are most useful for cutting ferrous metals like steel and aluminum.
Depending on the kind of work you are doing,proper selection of a blade is an essential.Each blade is made with a different function in mind and if we do put up a wrong blade at a wrong place,then the whole activity is going to be adversely affected.
