ASME B94.54:1999(R2020) pdf download.SPECIFICATIONS FOR HOLE SAWS, HOLE SAW ARBORS, AND HOLE SAW ACCESSORIES.
ASME B94.54 provides a useful criterion of practice in the production, distribution, and use of high-speed steel, grit edge, and carbide-tipped nonadjustable hole saws and their accessories.
This Standard covers definitions, standard sizes, dimensions, tolerances, tooth configuration, and quality requirements for the hole saws and their accessories covered by this Standard.
2 DEFINITIONS
blade: that part of the hole saw which is affixed to the cap and is comprised of the cylindrical body and eeth.
body. that part of the blade beween the bottom of the gullet and cap (see Fig. 1).
built-in arbor. an arbor that is fabricated integrally with the cap of the hole saw.
cap (sometimes called a cup): the component to which the arbor is atached to drive the hole saw blade.
curling depth: the overall distance between the point of the tooth or grit and the edge or lip of the cap nearest the teeth.
culling edge: that edge of the face of the tooth which is intended to perform cutting. It is formed by the intersection of the flank and the face (see Fig. 6). (Sce para. 4.1.5 for exceptions.)
direction of rotation: looking at a hole saw from the threaded end (opposite the teeth), the saw shall be rotated in a clockwise direction.
explanatory inft.rmation: when provided in this Standard, it will be identified as such and is not part of the Sandard. ft will be used to help clarify the various facets of the Standard.
gullet. the space between teeth points that permits chip removal (see Fig. 6).
kef: the width of cut produced by the overall set of the teeth (see Fig. 5).
saw diameter: the diameter of a saw shall be determined by measuring at the outer limits of the Set of the teeth or grit, rather than at the body of the blade.
shall: to be understood as mandatory. should: to be undcrstood as advisory. tables: all tables used in this Standard arc applicable to the Standard.
teeth: the serrations formed across the thickness of the blade to provide cutting edges (see Fig. I). thickness of the blade: the distance between the two cylindrical surfaces of the body (see Fig. 5).
tooth crest plane: the place perpendicular to the axis of the hole saw that includes the extreme point of the cutting edge.
tooth depth: the distance from the point of the tooth to the deepest portion of the gullet measured parallel to the axis of the hole saw (see Fig. 6).
tooth face. that surface of the tooth over which the chip flows (see Fig. 6).
tooiJz pitch: the distance between apices of adjacent teeth measured in inches. Teeth per unit length is expressed as the number of complete teeth per 1 in. length.
tooth set: the transverse projection of the teeth from the side of the blade to provide he cutting clearance.
toothed edge: the edge of the blade (or body) along which the teeth have been formed (see Fig. 1).ASME B94.54 pdf download.
