(2) Circular saw blades (including slittin or slotting saw blades for use on milling machines). The latter can be distinguishe from millin cutters by the ratio of thickness to diameter which is less than for milling cutters, and y the toothing which is'cut only on the periphery as with ordinary circular saws, whereas milling cutters often have teeth on their faces, or have concave or convex teeth. f (3) Chain saw blades (in the form of chains for felling trees, sawing up tree trunks, etc. The teeth of such blades often comprise e ements of metal carbides or cemets. ? (4) Strai ht saw blades for panel saws, tenon saws, hack saws, etc., includin those for saws &,own as " filigree saws " (round blades toothed like a file, but used or sawing like a fret saw blade). f (5) Strai ht toothless stone cutting saw blades (either hammered or machine dressed so as to e quite flat, or corrugated) provided their extremities are perforated or otherwise shaped for fixing, (6) Toothless cutting discs (friction discs) for cutting through metals. The headin also covers saw blade blanks. Provided that they are toothed, strip whether or not cut to lm$) and discs (with a central hole for fixin the disc to the driving sha ) are regarded as such b anks. These articles are usually of steel witl? a high carbon content. k Saw blades may have integral teeth or be fitted with inserted teeth or se ents (such as some circular saws). The teeth may be wholly of base metal, or of base metal ltted or covered with metal carbides, diamond (black diamonds in articular) or, in some cases, with abrasive powders. In some saws the teeth may be replace by diamonds or by elements of metal carbides set around the periphery of the disc. !? a Toothless discs fitted with abrasive rims (e.g., for cutting marble, uartz or glass) or with a series of peripheral inserts of abrasive material are, however, excluded (see the xplanatory Note to heading 68.04). The headin includes separately presented base metal parts of hand saws (e.g, fiames, bows, handles an stretchers) and base metal teeth and toothed segments for insertion m saw blades. t The heading also excludes : (a) Stone sawing strand (usually three-ply stranded wire of special steel) (heading 73.12). (b) Morticing chain cutters (heading 82.07). (c) Hand saws with self-contained motor (heading 84.67). (d) Musical saws (heading 92.08).
