This is the top grade of three U.S. Saws publishes on its small-diameter concrete blade line, and it is a narrower range than the grade below it on purpose. Every size here is a thick section, .250 in or .375 in, which is the width a joint needs when the fill goes back in behind the saw rather than the width for opening a hairline. The grade below runs from .080 in up and covers the thin work; this one starts where that one leaves off.

Eight of the ten sizes are a plain 7/8 in arbor for a grinder or a joint clean-out saw. The other two are built for the CC-100 crack chaser and mount on a 5/8 in bore with a drive pin hole, which is what stops the blade slipping on the arbor when the saw loads up in a deep chase. Those two are the most expensive sizes in the line by a wide margin, and U.S. Saws says why in its own copy: the highest grade of diamond it stocks is what makes them acceptable on that machine.

Common Applications

  • Joint clean-out on concrete ahead of a polyurea or epoxy fill
  • Crack chasing on concrete and masonry
  • Cutting on the U.S. Saws Dust Buggy series joint clean-out saws
  • Crack chasing on the CC-100, on the two sizes built for it

Selection Notes

  • Match the mount to the machine before the diameter: the two 5/8 in crack chaser sizes will not fit a plain 7/8 in arbor and the reverse is also true
  • Both section widths are published at every diameter from 4 in to 6 in; the 8 in is published at .250 in only
  • Two 8 in part numbers share one size and one bore and are priced $4.60 apart, and the only difference U.S. Saws states is which saw each names
  • U.S. Saws publishes no weight that distinguishes one size in this line from another
