W1218A Rotacator®

The Rotacator® is a versatile and easy to use magnetic base setup tool.

Accuracy matters and the Rotacator® will help keep your shop tools in their top working condition.

The Rotacator® is ideal for checking multiple machine setups, tolerances and adjustments. Fine-tune your machine for that “like new” performance. It will help you perfectly set jointer knives and parallel your table saw blade to the miter slot. Use the Rotacator® with its dial indicator to check for runout on machines around the shop.

Use the Rotacator® to eliminate unwanted non-parallel surfaces.

Eliminate chatter, spot wobble and runout. Pinpoint accuracy when tuning blades, feed rollers, chip breakers, pressure bars and more.

Ensure your infeed and outfeed rollers are parallel to the machine bed for consistent, even feed rate and reduced chatter. Keep the chip breaker adjusted just right for maximum dust collection efficiency. Re-set your pressure bar to reduce planer snipe and chatter.

Indicator rotates 360° for fine adjustments at any angle. Zeroing out the dial is as easy as rotating the indicator face.

W1218A Rotacator® comes with a 1-year warranty which assures the unit is free from factory defects.

The Grizzly Customer Service and Technical Support Teams are U.S. based.

Includes two interchangeable indicating tips: (1) small tip and (1) wide tip.

Essential tool 07/15/2020 5:50:12 PM

This tool is essential for fine-tuning in-feed roller, out-feed roller, and cutting blade alignment on my Grizzly 20" 3hp planer. Excellent design with magnetic base to keep gauge steady while adjusting roller/blade height/depth. Solid/precise adjustment dial and locks.

Sweet tool....should have got when I bought the planer 06/18/2020 8:13:10 PM

I bought instead of a the 2x4 method, have been told right tool for the job. I got it, cleaned it, and used it. It made life so much easier and faster. I would recommend using a ratchet and socket on the jamb nuts.

Very helpful and EZ to use. 05/17/2020 1:23:01 PM

oh, my gosh. My life just got easier! You can not verify or adjust your planer with out this little baby. If your sanity and maintaining your Christian witness is important to you, then this is for you.

This is a must have tool for the planer 12/31/2018 4:28:33 PM

This item is a must to set up the planer right way. It's well made, and its strong magnets in the base, holds it to the table really well. I had my new planer setup in no time with this. This is a must have tool.

This is a well made product. Highly recommend this for setting heights on items like bed rollers on planers.

This tool worked great for helping in setting up my planer. The only thing I didn't like is the magnet.

Great so far 02/04/2017 9:56:52 AM

This planer was a serious upgrade from my 12" bench top. It is one heavy peace of machinery. So far I have used it to plane down some 15"-19" rough cut timber and it performed flawless. It did take some messing with to get the pressure bar to stop chattering "increased the clearance". Other than that no complaints. The shipping was fast and the machine arrived well packaged and unharmed.
