Under work pressure the saw blade deflectsso that it is supported on points only. A hard-ened steel guide such as a ball bearing guidecannot adjust itself and will tear and chew thesaw blade from the rear which will greatly

shorten the life ol the blade. The microscopic viewshows what happens to a saw blade when used withnon-self-seating guides

GNOB SETf.SEATING GUIDESSAVE SAW BI.AIDES

The problem to provide a large bearing sur-Iace under varying working pressure hasbeen solved with the Grob guides. After"seating" itself in the guide the back of thebale wears smooth as shown by microscopicview. Note how the surlace is actually im-

proved over new unused saw blade. Long life o{ theguides is assured by a felt oiler mounted directly abovethe upper guide.

Grob self-seating guides with the new Grob Lubricator are now recognizedas the most perfect and only satisfactory guide for contour metal sawing.The guides are made of tough hard aluminum bronze, Rockwell C-34.
