The Master Cobalt reciprocating saw blades are for cutting wood and nail-embedded wood. Utilizing an innovative tooth geometry and set pattern, this new blade increases productivity while decreasing the cost per cut. The larger tooth and increased weld contact area on the 5.5 TPI blade result in a more durable blade than traditional blades. The technologically advanced tooth design allows for increased shock and wear resistance, in addition to more aggressive cutting with more teeth engaged. The blade averages more than 500 nail cuts before showing any initial tooth strippage. More cuts per blade means less time changing blades and more time getting the job done. The 5.5-pitch, .050 thick-blades are available in 6, 9 and 12 inch lengths.
