Abstract

A saw arrangement includes the combination of a saw blade and a lubrication guide support. The saw blade has a planar saw body and a cutting edge defining a rotational direction for cutting. The planar saw body has a planar annular section with oppositely facing parallel surfaces and an axial thickness therebetween. The planar annular section also defines a plurality of cavities therein. The lubricating guide support has a bearing surface adjacent the saw body for proper alignment of the saw blade during cutting. The guide support contains liquid exposed to the saw body at the bearing surface whereby liquid is applied to the saw body as it passes by the bearing surface. The cavities pass by the exposed liquid during movement of the saw blade. The cumulative opening area of the plurality of cavities equals approximately six percent of a cutting triangle of the circular saw blade.
