A high speed rotatable elongated holeless reinforced resin bonded abrasive body (10) comprising a central mounting portion (12) including diametrically opposite arcuate segments (14) with arcuate inclined surfaces (16) angularly displaced normal to diametrically opposite grinding portions (18) extending radially therefrom to arcuate grinding surfaces (22) and reinforcing elements (26) bonded to and extending continuously through the central portion (12) and grinding portion (18). Spindle mounting means (40) (70) are provided with inner drive flanges (44) (74) and outer clamping flange (60) for clamping and driving a single abrasive body (10) an outer flange (90) for clamping and driving a plurality of angularly spaced abrasive bodies (10a and 10b) and to which flanges (60) (90) additional similar clamping drive means may be fastened and angularly spaced from one other, to mount additional abrasive bodies (10) to the spindle mounting means (40) (70).
