The Bosch Standard Sandwich Tuckpointing Blade features a double-blade sandwich design, for fast efficient mortar removal with a long-lasting blade. Used with a handheld small angle grinder and a tuck point attachment, this blade provides long life and fast mortar removal. The dual blade stack provides quick, consistent material removal, and the connected blades optimize performance over single blades stacked with washer. The Industrial-quality diamonds produce a cutting surface optimized for thorough cleaning and extended life. The blade features a 0.25 In. segment thickness. It works with a 7/8 In. arbor. These blades are ideal for use with the Bosch PRO+GUARD™ dust system. This end-to-end system helps users move toward compliance with the OSHA respirable crystalline silica dust regulation.
