E-Z Burr Announcement: Adjustment Screw Changes

In an effort to continuously upgrade and improve our E-Z Burr tools, we are proud to announce two important changes to our adjustment screws that have immediately been put into effect.

E-Z Burr Tool Company is now using Loctite 242 to replace the Loctite 222 that we have previously been using on adjustment screws on our deburring tools.

Through extensive testing, we have found that the additional strength and holding power of the Loctite 242 ensures that the adjustment screw will stay in place through machine vibrations. The position of the blade will be consistent from blade to blade and will eliminate the possibility of the blade height or tension from wandering.

Of course after multiple adjustments, a small drop of Loctite 242 should be re-applied to restore the security of the screw.

E-Z Burr Tool Company will also be supplying a 5/64 hex size screw instead of our previous standard screw hex of 3/32. The new screws have been installed in all of our tools and will provide a stronger, more improved hex that will not break when additional torque is placed on it. Combined with the Loctite 242, this change in hex will increase the resistance to vibration and will prevent the chance of the screw loosening.

When our tools are assembled at the factory, we apply a small drop of Loctite 242 MS “Thread locker” to the adjustment screw. We then adjust the blade or insert to the proper height which is typically a low height to prevent too much initial cutting action. We understand that customers will adjust the blade to achieve the proper chamfer required for their specific application, however once proper chamfer is achieved we recommend that the adjusting screw not be moved.

If the Locktite loses it effectiveness, this could allow the adjustment screw to roam, which may cause the blade or insert height to waver and the chamfer will be inconsistent. We recommend the following. By using a standard Allen wrench to back the adjusting screw out to expose 3 to 4 threads, apply a small drop of Loctite 242 to the threads, adjust the blade or insert to the proper cutting height.

The adjustment screw does not need to be touched during blade replacement and the blade does not need to be touched during adjustment. Please remember that locking screws and adjustment screws have two separate and unrelated functions. You do not have to “unlock” the locking screw to adjust the blade, nor do you have to back the adjustment screw out to remove a blade or insert. In fact, that will actually harm the tool and possibly result in “stripped threads.”
