Tommy Hall Posted November 23, 2020 Report Share Posted November 23, 2020 Has anyone rotated the blades on their Dewalt 735 with the spiral cutter. Two of us at the shop gave it a try with some success but they are not perfect like when it was new. Any input would be appreciated.

wtnhighlander Posted November 23, 2020 Report Share Posted November 23, 2020 Disclaimer: This comment is based on hearsay, not personal experience. When rotating the carbide cutters, it is ABSOLUTELY IMPERATIVE to clean the cutter, the screw, and the surface of the head to remove ALL particulates. The tiniest bit of wood dust will prevent the cutter from seating properly, producing a mark in tbe cut. A larger or harder particle can even allow the carbide cutter to crack when tightened. If you did all that, then perhaps there is a variation in cutter manufacture? The maker of the head may have advice to offer. 1 Quote Link to comment Share on other sites More sharing options...

Tommy Hall Amesbury, MA Can I ask why you needed to rotate the cutters? I have had my spiral cutter installed for close to 6yrs now and it still cuts like new. But as @wtnhighlander said the cutter has to be spotless for the cutters to seat correctly. Quote Link to comment Share on other sites More sharing options...
Chestnut Posted November 23, 2020 Report Share Posted November 23, 2020 Follow the instructions here. https://storage.googleapis.com/wzukusers/user-26182198/documents/5a6b670f80299V7oHSw2/shelix knife replacement or rotating.pdf Use a torque wrench to get the exact same torque on each cutter. This one is good. https://www.amazon.com/gp/product/B01M12284X/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 8 hours ago, Just Bob said: Can I ask why you needed to rotate the cutters?

I agree and disagree. Years is a bad measurement as you may run 500 BF through your planer in 6 years while another guy may run 2,000 BF in 3 years. Also material type and condition matters. 50BF of painted material could will wear the cutters out. Dirt and other debris matters too. Even BF is a poor measurement as full width linear feet is probably the most accurate but also the most difficult. I have about 500-750 BF of material through my planer and the knives are still good. I'd venture a guess that i could run close to 2,000 BF before needing to rotate. If you run a couple hundred feet a year that's 10 years.

Tommy Hall Posted November 25, 2020 Author Report Share Posted November 25, 2020 We used it for probable 3 years with clean soft maple and other hardwoods, many thousands of feet. We found it amazing how sharp and long they lasted. We did not cleaned them, just blowing them out, that could be the issue. Thank for the input.
