ABSTRACT:
The present invention relates to a saw blade holder for precision saws. Precision saws are designed to hold a saw blade between two parallel arms. Upper and lower blade holders mount the saw blade on the arms. The present invention relates to the lower blade holder and comprises two clamping elements which are designed to threadably engage and fit inside of a slotted tubular member. The blade passes through the slot in the tubular member and is clamped between the two clamping elements. The tubular member is comprised of a finely divided metal which has been shaped into the desired configuration utilizing a lubricant which is embedded throughout the thickness of the tubular sleeve. This lubricant is released over the lifetime of the tubular member so as to continually lubricate the wear points thus reducing wear and the adverse effects associated therewith.
