The industry’s only instant self setting knife that goes into your Grizzly machine as quickly as it comes out. Effortless knife changes with precision accuracy every time.

1st time System includes one set of reusable SELF-SET® knife holders and one set of disposable double edge HSS ‘Dispoz-A-Blade’ knives that are correctly sized for your machine. All that is required for future knife changes is the purchase of inexpensive ‘Dispoz-A Blade’ double edge replacement knives in either HSS or Cobalt steel.

Knife changes are as easy as snapping the disposable double edge knife onto the SELF-SET® holder and sliding the holder and knife into the knife pocket until the precisely located stops contact the outside surface of your planer or Jointer’s cutter head. The time it takes to change knives has now been reduced to the time needed to loosen the cutter head gib bolts, replace the dull edge and retighten. SELF-SET® eliminates all the time and frustration associated with changing knives and is much more economical than buying and re-sharpening standard knives. Dispoz-a-Blade’s trade tough German HSS and Cobalt steel double edge knives are always factory sharp for optimum performance. Unique to the industry, the SELF-SET knife installs in your machines ordinary stock cutter head eliminating the need to buy and install a special costly cutter head which is required by every other quick change knife system.
