G5912Z 5 HP Professional Spindle Shaper

Turn big shaper cutters with confidence.

The G5912Z 5 HP Professional Spindle Shaper handles cutters up to 5-7/8" diameter by 5-1/8" tall. The four speed V-belt drive system lets you slow down those big cutters from 10,000 RPM to 3600 RPM.

A cutter guard is bolted to the precision-ground cast-iron table. A micro-adjustable wooden split fence lets you dial in for full edge cutting support. Four spring-steel hold downs increase safety and production by holding the workpiece flat on the table and snug against the fence.

The G5912Z comes with three interchangeable spindles 1/2", 3/4" & 1" and three table inserts 7" OD x 3-1/2" ID, 3-1/2" OD x 3" ID & 3" OD x 2"ID.

Like all Grizzly shapers, the G5912Z comes with a 1-year warranty which covers parts and assures the unit is free from factory defects. (Consumables are not covered by the warranty.)

The G5912Z manual was written by our U.S. based Technical Documentation Department and is packed with useful information. The complete and easy to read manual makes it easier to assemble and maintain your shaper.

The Grizzly Customer Service and Technical Support Teams are U.S. based. Parts and accessories for the shaper are available on-line and shipped from the Grizzly parts warehouse in Springfield, MO.

Wow, I'll say it again, Wow!!! I received my order this last Friday and had a chance Saturday to unpack the machinery and assemble the parts. Whoever designs these machines at your company needs to go to Hawaii for 3 weeks!! They are awesome! For example, I set up my Extreme Series bandsaw G0513X2 and you guys thought of everything. The trunnion that has a lever action, geared head to precisely angle the table top. A tall re-saw fence, a miter head that has a pin to slide in to accurately and repeatedly set 0 and 45 degree settings. And the list goes on. Then there was the shaper G5912Z that had all the bells and whistles. Ratcheting setting bolts for the sliding fence, just like your ratchet set of your socket set you have in your tool box! Spring hold downs and 3 spindles. I commend all of you at Grizzly for your well thought out, well designed, and yes mind reading abilities for machinery that is going to make my woodworking life a whole lot easier.
