Jig Saw Features

• Variable Speed - Variable speed is an important feature to look for when buying a jig saw.  Variable speed allows the user to change the speed of the blade action depending upon what type of material you are cutting.  Most saws range from 500 to 3500 strokes per minute or SPM.
   
• Orbital Action – Orbital action refers to the blade action.  A jig saw moves the blade up and down in a straight line.  An orbital action jig saw will allow the user to press a switch and the blade will not only move up and down, but front to back as well.  This will cut through wood a lot faster than just the up and down motion.
   
• Adjustable Foot – An adjustable foot is the metal plate at the bottom of the saw which will pivot between 0 and 45 degrees.  This will allow you to make angle cuts in the wood
   
• Vacuum or Blower – A blower is a very nice feature.  As you cut your line with a jig saw, the wood particles tend to build up in front of the blade obscuring the cutting line.  A blower will blow these wood particles away allowing you to see the cutting line.
   
• Blade Changing – Look for a model that has a tool free blade changing system.  Some models require the user to use a tool to change the blade, but this can become a hassle.  Most models have a tool free blade changing system that will hold the blade in the arm no matter how much pressure you put on the tool when using it.
   
• Blade Support – A blade support is a little roller on the back by the blade that helps support the blade while using the tool.  This helps reduce flex in the blade which provides straighter cuts and longer blade life.
