Our Standard Abrasives™ Silicon Carbide 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 mainly for deburring applications on stainless steel, rubber, plastic and composites. It has a threaded eyelet arbor hole for mandrel attachment.
Coverage of Internal Diameters
For internal diameters that require increased coverage over a cross pad, our Standard Abrasives™ Silicon Carbide 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.
Sharp, Fast Cut and Fine Finish
Silicon carbide is a very hard and sharp mineral commonly used for low-pressure applications such as paint prep and the final stages of whitewood sanding. While it may have a shorter life than aluminum oxide, it produces a finer finish and should be used where the best possible finish is desired.
Running an Overlap Disc
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.
