Assembles Securely, Reliably, Quickly
Used for securing a square pad, a cross pad or cross buff to your 3M Die Grinder, the 3M Square/Cross Pad Mandrel allows you to make optimum use of your power tool by enabling it to accomplish more of the tasks you need to address.
This mandrel has a 1/4-inch shank that is engineered to fit your rotary power tool securely and allow for quick assembly. We make it available in 3 external thread sizes for running at a maximum rpm of 24,100.
Do More with One Tool
Our 3M Square/Cross Pad Mandrel allows you to use multiple type of abrasive products with one tool.
Square pads are ideal for fast grinding and blending of channels, fillets, corners and spotting on flat surfaces. As they rotate, the corners exert a fast biting action and gradually wear down to expose fresh abrasive material.
Cross pads are used for close tolerance polishing of small radii and channels, deburring the ends and insides of tubing and other special applications.
Cross buffs polish, clean, satin finish, denib and defuzz interior diameters of metal components.
Maximize the Value of Your 3M Power Tools
Engineered to work effectively with your 3M rotary tools, we design our accessories to perform to the highest standards, to allow you to do more, more cost-efficiently.
