Handheld power tools can cause serious injuries for workers in the manufacturing sector. Tools that fall into this category includes portable circular saws, routers, hand grinders, reciprocating saws, and jigsaws. These tools are very versatile, and as a result, are frequently used in tight quarters, on ladders, and for shaping and sizing small pieces where the work piece is held by hand. Unfortunately, with the high cutter speed, a slip or kickback can cause serious injuries to body parts.
