  • Numerous trades utilize reciprocating saws and blades to cut various objects. Plumbers utilize reciprocating saw blades to cut PVC pipe as well as to rough in holes in sub flooring. Heating and ventilating contractors utilize reciprocating saw blades to cut vents into sub flooring. Contractors utilize reciprocating saws to frame windows, doors, and the like. Also, renovation contractors utilize reciprocating saw blades to cut through nails and the like to remove walls and the like. These users rely on reciprocating saw blades that cut fast, have a desirable blade life or durability and enable easy plunge cutting that provides a fast, as well as a controlled cut. Available reciprocating saw blades that are utilized to plunge cut have a nose that, when it is plunged into the sub flooring or a workpiece, creates an enlarged inaccurate kurf. Thus, the reciprocating saw blade haphazardly bites into the workpiece. This slows the cutting process as well as provides the user with little or no control when plunging the reciprocating saw blade into the workpiece.

  • DETAILED DESCRIPTION
  • The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
  • Turning to the figures, particularly FIG. 1, a reciprocating saw blade is illustrated and designated with the reference numeral 10. The reciprocating saw blade 10 includes a body 12 which has a first shanking end 14 and a plunging nose end 16. The body 12 includes two edges. The first edge is a cutting edge 18 and the second edge is an opposing back edge 20. The cutting edge 18 includes a plurality of teeth 22. Each tooth includes a gullet 24. The gullets 24 are substantially identical and all have substantially the same size. Additionally, the teeth 22 are substantially identical and all have substantially the same size. Also, the teeth 22 are set teeth alternating left and right, separated by a raker, left, right. The left and right set can be alternated to provide a desired saw blade. The set of the teeth provides spacing for the body 12 and clearance for the back edge so that it can be maneuvered through the created kurf.
  • The plurality of teeth 22 includes a rake face 26 and a relief face 28. The rake face 26 and relief face 28 intersect one another to form a cutting edge 30. The rake face 26 is preferably at a rake angle α of about 3° to 10°. The relief face 28 is at a relief angle β from about 15° to 35°. The tooth 22 has an included angle δ of about 45° to about 72°.
  • The gullets 24 have a desired volume as illustrated in the shaded area of FIG. 3. The volume of each of the gullets 24 is substantially the same for all of the gullets 24.
  • The plunging end 16 has a first tooth 40 adjacent the end surface 42 of the plunging nose 16. The tooth 40 is a full tooth and is also a raker or unset tooth. The tooth 40 has substantially the same rake face 44 and rake angle as that previously discussed. The relief surface 46 is on a relief angle φ from about 35° to about 50°. Preferably, the relief angle is about 45°. The first tooth 40 may be offset toward the back edge 20 from a line through the cutting edges 30 to about 0.25 mm. This insures a sharp cutting edge on the first tooth 40.
  • A first gullet 48 is positioned adjacent the rake face 44. The first gullet 48 has a size from 1.5 to 5.5 times, preferably 2 to 5.5 times, the size of the remaining gullets 24. Thus, an enlarged gullet 48 is formed between the first tooth 40 and the remainder of the plurality of teeth 22. A second tooth has been removed or is missing from the plurality of teeth 22 to form the gap which creates the first gullet 48. Thus, by removing a tooth, this allows the first tooth 40 to cut into the workpiece so the third tooth 60 (first tooth of the remainder of the plurality of teeth 22) cannot engage or alter the path of the first tooth. Additionally, the third tooth 60 is preferably a raker or straight tooth This provides for a straight groove cut into the workpiece that is not influenced by the set plurality of teeth 22. Also, by having the first tooth 40 and a larger gullet, faster and greater chip removal is provided as well as an increased cutting speed.
  • The end surface 42 of the plunge nose 16 is on an angle of 35° to 45° and preferably 39° with respect to the longitudinal axis of the blade. This aggressive angle provides for clearance of the plunge nose 16 to enable it to plunge faster into the workpiece. Also, the end surface 42 intersects the relief surface 46 of the first tooth to form a cutting edge 52 at the tip of the blade. An included angle of about 60° to 90° is formed between the end surface 42 and relief surface 46. This enhances the chipping action of the reciprocating saw blade 10 once the saw blade enters into the kurf of the workpiece.
  • FIG. 5 illustrates a second embodiment. Here, the saw blade is the same as that previously disclosed; however, two teeth are missing out of the plurality of teeth behind the first tooth 40. This provides an even larger first gullet 48′ about 5.5 times the size of the remaining gullets. This enables the fast removal of chips to provide a faster cutting reciprocating saw blade.
  • Turning to FIG. 6, a method for manufacturing the blades is illustrated. Here, a stock coil 100 is fed into a die set 102. The coil stock 100 has had the teeth milled and set into the coil. The coil is unwound to have the teeth milled and set and then rewound after the teeth have been milled and set into the coil stock 100. The coil stock 100 is then fed into the die set 102. As the coil stock 100 enters the die set 102, the teeth 22 are located by a pilot stop 104. Two pilot stops 104 are illustrated which may be used on different size reciprocating saw blades. Since the die set 102 may be utilized to stamp 6″, 9″ and 12″ blades, only one die set 102 is needed to manufacture all three sizes. Rollers 106 advance the coil stock 100 into the die set 102. The pilot stops 104 locate the teeth and continue with the coil stock 100 into the die set. Coil stock 100 is stopped to enable a punch 108 to flatten at least three teeth of the unset teeth. The flattening occurs by compressing the punch together to provide a region that now has no defined tooth but a straight flat portion. The coil stock 100 continues to be fed into dies 110. As the coil stock 100 is positioned into the dies 110 with the fattened portion at the end of the dies 110. The dies 110 are closed and a punch progression begins to form the first tooth 40 as well as the enlarged gullet 48 into the flattened portion of coil stock to form the saw blade. Also, as this occurs, the coil stock 100 is continuously fed into an opening into the die 110 which forms the shanking end of the next reciprocating blade. It should be noted that the flattening, forming of the first tooth and enlarged gullet, as well as the forming of the shank end, takes place simultaneously in the die set at different locations along the die set. After the punching, the blade 10 exits the die set 102 with a first tooth and gullet as well as the plurality of teeth as explained above.
  • The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
