1-1/4x8-32x2 120gr A/O Overlap Disc

Our standard Abrasives™ zirconia overlap disc compresses when entering a hole or cylinder to provide coverage of inside diameters. Used for push and push pull applications, it is useful for mainly for deburring applications on steel, rubber, plastic and composites. It features a threaded eyelet arbor hole for mandrel attachment. For internal diameters that require increased coverage over a cross pad, our standard Abrasives™ zirconia overlap disc is a good option. The overlapping construction makes the disc flexible so that the operator can push it into a hole or tube and achieve full contact with internal diameters. Discs with four layers achieve abrasive action in both push and pull directions. Alumina zirconia (AZ) fractures frequently to continually produce fresh sharp points and delivers a faster cut rate than aluminum oxide. A man-made mineral, it was developed for heavy stock removal and high pressure grinding. For the convenience of tool-free disc changes, our overlap discs have a threaded eyelet arbor hole that screws onto a mandrel and is secured by hand with an attachment bolt (both available separately). A shorter mandrel allows for a steadier application, while a mandrel with extended reach allows access deeper into pipe interiors. Compatible threaded standard Abrasives™ mandrels are available separately with thread sizes of 8-32, 3-48 and 1/4-20. An extended version is available with 8-32 threads. The standard Abrasives™ brand has supplied quality abrasives to the metalworking industry for over 50 years.
