Description
Threaded Template Bushings-Flanged Type (TTBF)
An economical bushing designed for thin template jig plates from 3/64 to 3/8 thick. Bushings are held in place by a threaded Retainer Ring. Left-hand thread is self tightening during drilling to prevent the Retainer Ring from loosening. Flush contact of the Retainer Ring against the jig plate ensures perpendicular drill alignment. OD serrations prevent the bushing from rotating during drilling. Choose standard countersunk type for flush mounting, or flanged type for installation without countersinking the jig plate. Threaded Template Bushings can be easily removed to replace or reuse. Made in USA.
Application Information
