Makita S1122AF Reciprocating Saw Blades for Metal, 225 mm, 24 TPI, BiM, 2 pcs.

The Makita S1122AF reciprocating saw blades are professional-grade cutting tools engineered specifically for metalworking applications. These blades feature a robust Bi-Metal (BiM) construction, which combines a flexible carbon steel body with a high-speed steel tooth edge to provide a balance of durability, heat resistance, and break resistance during demanding cutting operations. With a length of 225 mm and a fine tooth configuration of 24 TPI, these blades are optimized for delivering smooth, precise cuts in various metal profiles and sheets.

Advantages

The primary advantage of these Bi-Metal blades lies in their exceptional resilience and longevity compared to standard carbon steel blades. The high tooth count ensures a clean finish with minimal burring, which is essential for professional metal fabrication. Their flexibility allows the blade to withstand the stresses of reciprocating motion without snapping, while the high-quality material composition maintains sharpness over extended periods of use, reducing the frequency of blade changes and increasing overall work efficiency.

Suitable for

• Cutting thin to medium-thickness metal sheets
• Trimming metal pipes and conduits
• General metal fabrication and repair tasks
• Demolition work involving metal components

These blades may not be suitable for cutting very thick metal sections or hardened steel, as the fine 24 TPI tooth pattern is designed for thinner materials and may clog or wear prematurely when used on heavy-duty structural steel. They are also not intended for cutting non-metallic materials like wood or masonry, which would require different blade geometries.

Key specifications

• Blade length: 225 mm
• Tooth pitch: 24 TPI
• Material: Bi-Metal (BiM)
• Quantity: 2 pieces
• Compatibility: Standard reciprocating saw shanks

To use these blades, insert the shank securely into the reciprocating saw blade clamp until it clicks or is firmly tightened. Ensure the saw is unplugged or the battery is removed during installation. Position the blade against the workpiece before starting the tool, and maintain steady, moderate pressure while allowing the saw's reciprocating action to perform the cutting. Avoid excessive force, which can cause the blade to overheat or bend.

What to consider before purchase

• Verify the compatibility of your reciprocating saw shank type
• Ensure the 225 mm length is appropriate for the depth of your intended cuts
• Confirm that the 24 TPI tooth count is suitable for the thickness of the metal you are cutting

For optimal performance and extended blade life, use a suitable cutting lubricant or coolant when working with ferrous metals and maintain a consistent cutting speed to prevent overheating the blade teeth.
