The 3" Teardrop Standard 3 Seg Soft Bond is a diamond abrasive tool designed for the WerkMaster Scarab and Termite XT floor grinding machines. This diamond attachment is ideal for grinding concrete, stone, and terrazzo surfaces. The "3 Seg" refers to the three diamond segments attached to the underside of the teardrop shaped tool. The soft bond refers to the strength of the diamond abrasive attachment to the tool (MOHS 7.5 and up). A soft bond is good for cap cutting and hard concrete grinding applications and for creating a CSP 2 profile for thin mill coatings.
