Reciprocating Saw Blade M.K. Morse Master Cobalt 18 TPI 152x20x0.9mm 5 pcs bi-metal

Bi-metal reciprocating saw blades M.K. Morse Master Cobalt, 18 TPI, 152 x 20 x 0.9 mm, pack of 5. These sabre saw blades combine high-speed steel cutting edges with a flexible spring-steel backing to deliver a balance of edge hardness and fatigue resistance. With a fine 18 teeth per inch geometry and cobalt-enhanced cutting edge, the blades are designed for more controlled, precise cuts in metal and mixed-material demolition tasks. Each blade fits standard reciprocating saw holders and is supplied in a five-piece pack for replacement and job-site readiness.

Advantages

The bi-metal construction pairs hardness for wear resistance with a tougher backing to reduce breakage during aggressive cutting. The cobalt-enhanced cutting edge improves durability and heat resistance when cutting metals, extending usable life compared to standard carbon blades. The 18 TPI tooth pitch produces smoother, more controlled cuts in thin to medium-thickness metal and helps reduce material splintering when working with multi-layer assemblies. Pack of five blades ensures quick replacement and uninterrupted workflow.

Suitable for

• Cutting steel sheets, pipes and profiles
• Demolition work involving mixed materials (metal, wood with nails, composites)
• Plumbing and HVAC disassembly or retrofit tasks
• Fine, controlled metal cutting where reduced burr and improved finish are needed

Key specifications

• Blade length: 152 mm
• Blade width: 20 mm
• Blade thickness: 0.9 mm
• Tooth pitch: 18 TPI (teeth per inch) for fine cutting
• Material: bi-metal construction with cobalt-enhanced cutting edge
• Pack quantity: 5 blades
• Compatibility: standard reciprocating (sabre) saw holders

How to use

Select a blade and install it according to the reciprocating saw manufacturer's instructions, ensuring the blade is seated and secured in the holder with the teeth oriented away from the saw body. Begin cutting at a moderate speed to establish a steady kerf, applying consistent feed pressure; let the blade do the cutting rather than forcing it. For metal cutting, use cutting lubricant or coolant as appropriate to reduce heat and extend blade life. Replace blades when cutting performance decreases or teeth are visibly worn.

Usage recommendations

Use the 18 TPI Master Cobalt blades for thin to medium metal sections and where a smoother finish is required. Avoid excessive side-loading or twisting motions to prevent premature fatigue of the blade. For thicker structural steel or faster rough cuts, choose a blade with a coarser tooth pitch; for stainless or hardened alloys consider reducing speed and using coolant to manage heat.
