Makita B-31859-2 Sabre Saw Blade 228mm Bi-Metal for Wood and Metal

The Makita B-31859-2 is a high-performance 228mm bi-metal reciprocating saw blade engineered for versatile cutting tasks involving both wood and metal. This blade is designed to withstand the rigors of professional construction and demolition work, offering a balance of flexibility and durability that prevents breakage while maintaining a sharp cutting edge. Its bi-metal construction combines high-speed steel teeth with a flexible carbon steel body, ensuring efficient material removal and a long service life even under demanding conditions.

Advantages

The primary advantage of this bi-metal blade is its exceptional versatility, allowing users to switch between cutting wood and metal without needing to change the tool accessory. The robust design minimizes the risk of tooth stripping and blade snapping, which is critical when working with embedded nails or composite materials. Furthermore, the 228mm length provides sufficient reach for deep cuts, making it an essential component for heavy-duty reciprocating saws in various trade applications.

Suitable for

• Demolition of wooden structures with embedded nails
• Cutting through metal pipes and profiles
• General renovation and construction tasks
• Cutting thick wooden beams and boards

When it may not be suitable

This blade is not intended for precision fine-woodworking where a smooth, splinter-free finish is required, as the tooth geometry is optimized for speed and durability rather than surface quality. Additionally, it is not suitable for cutting hardened steel or masonry materials, which would cause rapid wear and damage to the blade teeth.

Key specifications

• Blade length: 228mm
• Material composition: Bi-Metal (BIM)
• Compatibility: Standard reciprocating saw shank
• Quantity: 2 blades per pack

How to use

To use the blade, ensure your reciprocating saw is disconnected from the power source or that the battery is removed. Insert the blade shank into the saw's blade clamp until it clicks securely into place. Verify that the blade is locked before reconnecting power. When cutting, maintain firm contact between the saw's shoe and the workpiece to minimize vibration and ensure a controlled, efficient cut. Apply steady pressure and allow the blade to do the work, avoiding excessive force that could cause the blade to overheat.

What to consider before purchase

• Check the compatibility of your reciprocating saw's blade clamping system
• Ensure the 228mm length is appropriate for the thickness of the materials you intend to cut
• Consider the material hardness to ensure it falls within the capabilities of bi-metal blades

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating a reciprocating saw. Inspect the blade for signs of wear or damage before each use and replace it if the teeth become dull to maintain cutting efficiency and safety.
