High-Velocity Bi-Metal Reciprocating Saw Blades for Clean Sheet Metal Penetrations

The Bosch RM618 6-Inch 18 TPI Bi-Metal Reciprocating Saw Blade set delivers a commercial-grade cutting solution engineered to execute fast, straight cuts through thin-gauge structural metals, electrical conduit, and plumbing lines. Each blade incorporates a hardened high-speed steel cutting edge electron-beam welded to a flexible carbon steel backing to maximize thermal wear resistance and prevent structural shattering under heavy load forces. An innovative pair-setting tooth geometry features alternating left-and-right indexing pairs that accelerate chip clearance while maximizing individual tooth service life. Optimized with a thin-kerf 0.035-inch thickness, these multi-purpose blades supply the exact lateral flex required for tight flush-trimming tasks without sacrificing vertical tracking stability.

Best Used For:

  • Sheet Metal Alterations: Slicing cleanly through 10-gauge to 16-gauge ferrous and non-ferrous plates or HVAC metal ductwork systems.
  • Electrical Conduit Trimming: Sectioning industrial steel conduit pipes, aluminum wall studs, and metallic utility enclosures.
  • Plumbing Demolition Work: Executing flat flush cuts against wall plates through residential copper pipes and copper tubing networks.

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.
  • Thin Metal Optimization: Precision-ground 18 TPI configuration is balanced to cut sheet materials ranging from 10 to 16 gauge.
  • 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 thin-gauge sheet metal, secure the workpiece close to the cut line to mitigate chatter. Allow the 18 TPI pair-setting tooth geometry to engage the metal surface at moderate tool speed to optimize chip ejection and protect the bi-metal matrix.
