Porter-Cable's model 9543 jigsaw, on sale this month, trims the time needed to do that down to seconds. The company designed an innovative keyless blade clamp that makes blade changes easy. Just squeeze the two levers with thumb and forefinger, insert the blade, then release. You don't need a wrench to tilt the base of the jigsaw, either, thanks to a built-in locking mechanism. And if you are working on laminates and veneers, you can attach a plastic sub-base over the cast metal base to protect your surface.
Internal bearings create the clamping force that grips the bit.
The quick-changer will appear on other routers in the coming months, and be sold by Jacobs to retrofit existing routers as well. Terms and Conditions of Use.
