Utilize maximum cutting efficiency with three teeth sizes. Lead off with 32tpi, move to 24tpi for more agressive strokes, and complete the stroke with 18tpi. or isolate the blade to use only one section. Bi-metal hack blades will bend and flex, resisting shattering for safer sawing and longer lasting blades.
One blade 3 options
Vacuum heat treating creates harder edge for faster, easier cutting
High speed steel cutting edge with 8% cobalt for longer blade life
Increased heat and wear resistance for longer life
Flexible to prevent shattering during use
Will cut through pipe, tubing, solids, wood, plastic or any machinable metal
