PartNumber : CL-22018-TIP ProductDescription : Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15? taper on the plunger tip with a mating taper in the bushing. The taper makes alignment easier and also eliminates any binding during retraction (also available with a straight plunger, for slightly greater positional accuracy). The rotary-cam version completely retracts when the handle is rotated 180?. Cam surfaces are hardened steel. The standard-mount configuration shown here has a precision ground body with a whistle notch for orientation with a setscrew (also available with a slightly oversize unground body to allow custom grinding to size). Order plunger and bushing separately. Made in USA. ProductSiteLaunchDate : 2013-12-22T21:57:43.582Z
