High-Performance Bi-Metal Reciprocating Saw Blades for Clean Medium-Gauge Metal Penetrations
The Bosch RM918 9-Inch 18 TPI Bi-Metal Reciprocating Saw Blade pack provides an industrial cutting solution engineered to execute fast, straight cuts through medium-gauge structural metals and industrial piping. Each blade incorporates a hardened cutting edge seamlessly bonded to a flexible carbon steel backing to maximize thermal wear resistance and eliminate blade fracturing under heavy jobsite loads. An innovative pair-setting tooth geometry features alternating left-and-right pairs that accelerate structural material removal while maximizing individual tooth service life. Optimized with a thin-kerf 0.035-inch structural body thickness, these multi-purpose blades supply the exact lateral flex required for flush trimming without sacrificing the column rigidity needed for vertical cutting accuracy.
Best Used For:
- Industrial Pipe Dismantling: Slicing cleanly through medium-gauge steel pipes, copper utility lines, and structural conduit lines.
- Metal Profile Modifications: Sectioning non-ferrous aluminum extrusions, ferrous metal studs, and structural steel framing profiles.
- Commercial Demolition Tasks: Executing flat flush cuts against wall and flooring plates through iron piping arrays and sheet metal enclosures.
Key Performance & Safety Features
- Bi-Metal Durability Matrix: Fuses a fatigue-resistant flexible steel body with a high-speed steel cutting edge to prolong tool longevity.
- Medium Metal Optimization: Precision-ground 18 TPI configuration is balanced to cut materials ranging from 1/8 inch to 5/16 inch in thickness.
- Pair-Setting Tooth Layout: Double-tooth indexing pattern (two left, two right) forces faster chip clearing and increases cutting velocity.
- Thin Kerf Profiling: Rigid 0.035-inch cross-section permits easy plunges, clean entries, and optimal flexibility for tight architectural spaces.
- Tilt Angle Mechanics: Engineered 3-degree blade tilt angle maximizes aggressive tooth engagement to maintain smooth cutting arcs.

Pro-Tip: When cutting heavy steel profiles, avoid rocking the saw aggressively. Allow the 18 TPI pair-setting tooth geometry to engage the metal surface flatly at a steady reciprocating speed to optimize chip ejection and minimize tooth wear.
