Blade Types what type of blade to use?

In my application cheep material is blocking small dia soft plastic tubes,how can this avoided?

Remember to match the blade width to the type of cutting you are doing. Also keep in mind: * Narrow Blades can make much tighter radius cuts, but tend to twist and wander when making long straight cuts. * Wide Blades can't make the tight turns that narrow ones can, but they hold a straighter line than their narrow counterparts. * The tpi determines the speed with which the blade cuts through stock. Blades with high tpi cut slower but leave a very smooth edge. They are best for detail work on thin stock. Blades with low tpi cut quickly and leave a slightly rough edge. They are great for resawing or long rip cuts. * Steel Blades are inexpensive and work well for cutting softwood. Steel blades, however, dull quickly in hardwood. * Bimetal Blades are made of high-speed steel and can cut thin metal or wood. * Carbide Blades are for wood cutting only. They are more expensive than other blades but stay sharper longer than steel or high-speed steel.
