Saw Blade for Reciprocating Saw Makita B-43169-2 BIM 225 x 0.9 mm, 2 pcs — Metal 0.7–3.0 mm, Pipes 5–175 mm

Replacement bi-metal (BIM) saw blades Makita B-43169-2, 225 x 0.9 mm, set of 2 are intended for reciprocating (sabre) saws and designed for cutting thin sheet metal and pipes. These blades combine a high-speed steel cutting edge welded to a flexible spring steel back, providing an extended service life and resistance to breakage during demanding demolition, plumbing and metalworking tasks. The geometry and tooth pattern are optimised for controlled cutting of metals in the stated thickness and for making through-cuts in tubular materials.

Advantages

The bi-metal construction offers a balance of hardness and flexibility that increases blade life compared with standard carbon blades. With a 225 mm length and 0.9 mm thickness the blades give good reach and reduced material binding when cutting flat metal up to 3.0 mm thick. The pack of two ensures a spare blade is available for continued work. Tooth design and reinforcement at the joint between HSS and spring steel reduce the risk of premature failure when cutting reinforced or irregular sections.

Suitable for

• Cutting sheet metal 0.7–3.0 mm thick
• Cutting metal pipes and tubing with diameters 5–175 mm
• Demolition tasks involving small metal profiles and fasteners
• Plumbing work requiring removal or cutting of metal pipes
• General metalworking where a durable reciprocating saw blade is required

Key specifications

• Length: 225 mm
• Thickness: 0.9 mm
• Recommended cutting material thickness: 0.7–3.0 mm for flat metal
• Suitable pipe diameter range: 5–175 mm
• Quantity: 2 blades per pack
• Compatibility: Standard reciprocating (sabre) saw blade shank systems

How to use

Install the blade into a reciprocating saw following the saw manufacturer's instructions, ensuring the blade is oriented with the teeth facing the correct cutting direction and locked securely. Set saw speed appropriate for the metal thickness—lower speeds for thicker or harder metals to reduce heat and wear. Use steady, controlled feed pressure; avoid forcing the blade through the material to prevent bending or premature wear. Allow the blade to complete the cut with consistent strokes and clear metal chips from the cutting area as needed.

Usage recommendations

For best results, use these Makita BIM blades on clean, properly supported workpieces and clamp thin sheet metal to minimise vibration. When cutting pipes, rotate the workpiece slowly or reposition the blade to maintain an even cutting line. Replace the blade when cutting becomes inconsistent, when chipping of teeth is visible, or when increased effort is required to maintain cutting speed.
