This Century Shark Tooth 7/8" bi-metal hole saw comes with its arbor already attached, so there is no separate arbor to buy or thread on. Professional 8% cobalt high speed steel teeth are electron welded to a shatterproof, shock absorbing alloy body, and the arbor attached saws carry an extra deep 1-3/4" cutting depth.
