Reciprocating saw blades Makita B-55837 BIM 305 x 1.1 mm 14+1 TPI, 5 pcs — for metal (225 mm usable length)

Set of five Makita B-55837 bi-metal (BIM) reciprocating saw blades, each 305 x 1.1 mm with a 14+1 TPI tooth configuration and 225 mm usable cutting length. These blades are designed for cutting a range of ferrous and non-ferrous metals and are intended for use with standard reciprocating saws in demolition, plumbing and metal fabrication tasks where a balance of cutting speed and edge life is required.

Advantages

Bi-metal construction combines flexible backing steel with hardened high-speed cutting edges to improve durability and resistance to breakage under heavy loads. The 14+1 TPI tooth pitch provides a compromise between aggressive material removal and controlled cutting of thin and medium-thickness metals. A 1.1 mm blade thickness offers stability during plunge cuts and long straight cuts while the 225 mm usable length enables access into deeper workpieces or through bundled materials. Supplied as a pack of five, the set reduces downtime by providing multiple blades for consecutive jobs.

Suitable for

• Cutting steel pipes and tubes in plumbing and HVAC work
• Demolition tasks involving metal framing and sections
• Metal fabrication and trimming of sheet metal and profiles
• Cutting bolts, nails and fasteners in retrofit or repair jobs
• On-site maintenance requiring durable reciprocating saw blades

Key specifications

• Blade length: 305 mm (225 mm usable cutting length)
• Thickness: 1.1 mm
• Tooth pitch: 14+1 TPI (teeth per inch)
• Material: bi-metal (BIM) construction
• Compatibility: standard reciprocating saw blade shank
• Quantity in pack: 5 blades

How to use

Fit the blade into the reciprocating saw according to the saw manufacturer's instructions, ensuring the blade is secured and oriented so the teeth face the material to be cut. Start cutting at a moderate speed to establish the kerf, then increase speed and apply steady, even pressure. For through-cuts use smooth, continuous strokes; for plunge or structural cuts, begin with a pilot entry or use a starter hole if possible. Replace blades when cutting performance declines, when teeth are visibly worn or when chipping occurs.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves and hearing protection) and secure the workpiece before cutting. For prolonged blade life when cutting thicker or hardened metals, use intermittent cutting with cooling intervals and avoid excessive side pressure that can cause premature wear or breakage.
