Blade for a reciprocating saw

A reciprocating saw comprising:

• a housing;
• a motor supported by the housing;
• a blade clamp mechanism supported for reciprocating motion relative to the housing;
• a drive mechanism connected between the motor and the blade clamp mechanism to impart reciprocating motion to the blade clamp mechanism;
• and a blade including
• an attachment portion coupled to the blade clamp mechanism;
• a body including a first profile portion extending from the attachment portion and a second profile portion extending away from the first profile portion and a transition portion between the first profile portion and the second profile portion, wherein the transition portion is steeper than the first and second profile portions;
• a plurality of teeth formed on the body and defining a toothed cutting edge;
• and a tip portion formed at a distal end of the second profile portion from first and second substantially straight edges intersecting at an angle of less than 90 degrees with respect to each other to form a pointed tip, the pointed tip configured to punch a hole through the workpiece, the first substantially straight edge including a toothless cutting edge extending substantially parallel to the toothed cutting edge, wherein the toothless cutting edge extends from the toothed cutting edge to the pointed tip, the second substantially straight edge ending opposite the pointed tip in a termination point defined at a junction of the second substantially straight edge and a non-collinear adjacent edge of the second profile portion, wherein a height at the termination point is less than half a height of the first profile portion;
• wherein an overall length of the blade is between about 2.75 inches and about 4.5 inches, measured substantially parallel to the toothed cutting edge from a proximal end of the attachment portion to a distal end of the pointed tip;
• wherein the second profile portion includes a profile length between about 1.5 inches and about 3.0 inches, measured substantially parallel to the toothed cutting edge from a proximal end of the second profile portion to the distal end of the pointed tip;
• and
• wherein the plurality of teeth are on both the first and second profile portion and have a fine-pitched tooth form having tooth pitch of 0.055 inches or less.

A blade for use with a reciprocating saw, the blade comprising:

• an attachment portion configured to couple to the reciprocating saw;
• a body including a first profile portion extending from the attachment portion, a second profile portion extending away from the first profile portion, and a transition portion between the first profile portion and the second profile portion;
• a plurality of teeth formed on the body and defining a toothed cutting edge;
• and a tip portion formed at a distal end of the second profile portion from first and second toothless, substantially straight edges terminating in a pointed tip configured to punch a hole through the workpiece,
• wherein the first and second toothless, substantially straight edges intersect at an angle of less than 90 degrees with respect to each other to form the pointed tip, the first substantially straight edge extending substantially parallel to the toothed cutting edge, wherein the first substantially straight edge extends from the toothed cutting edge to the pointed tip, the second substantially straight edge ending opposite the pointed tip in a termination point defined at a junction of the second substantially straight edge and a non-collinear adjacent edge of the second profile portion, wherein the termination point is disposed between the pointed tip and the attachment portion, and wherein a height at the termination point is less than half a height of the first profile portion;
• wherein an overall length of the blade is between about 2.75 inches and about 4.5 inches, measured substantially parallel to the toothed cutting edge from a proximal end of the attachment portion to a distal end of the pointed tip;
• wherein the second profile portion includes a profile length between about 1.5 inches and about 3.0 inches, measured substantially parallel to the toothed cutting edge from a proximal end of the second profile portion to the distal end of the pointed tip;
• and
• wherein the plurality of teeth are on both the first and second profile portion and have a fine-pitched tooth form having tooth pitch of 0.055 inches or less.
