Professional Precision for Bulk Metal Cutting

The Bosch RM918-25B 9-Inch 18 TPI Bi-Metal Reciprocating Saw Blade 25-Pack is engineered for professional contractors who demand durability, flexibility, and consistent performance when cutting metal. Designed specifically for medium-gauge metals ranging from 1/8-inch to 5/16-inch thick, these blades are ideal for slicing through metal profiles, structural pipes, and sheet metal. The advanced bi-metal construction fuses a flexible steel back with a hardened cutting edge, delivering outstanding toughness that resists breakage even during demanding demolition or renovation tasks involving ferrous and non-ferrous materials.

Performance is enhanced by Bosch's innovative "pair-setting" tooth geometry—featuring two teeth facing left followed by two teeth facing right—which ensures significantly faster cuts and longer blade life compared to standard configurations. With a thin-kerf 0.035-inch body, these blades provide the flexibility required for flush cuts while maintaining enough rigidity for accurate, straight cuts. The 3-degree tilt angle and 0-degree hook angle work in tandem to optimize cutting speed and cleanliness, making this bulk 25-pack an essential, cost-effective addition to any jobsite toolkit.

Key Features

  • Bi-Metal Durability: Combines a flexible body with a hardened cutting edge for superior toughness and extended life.
  • Optimized for Metal: 18 TPI configuration is perfect for cutting medium metal thickness (1/8 in. to 5/16 in.).
  • Fast Cutting Geometry: Pair-setting tooth design (2 left, 2 right) accelerates cutting speed and efficiency.
  • Thin Kerf Design: 0.035-inch thick body allows for flexibility, accurate cuts, and easier starts.
  • Straight Cuts: 3/4-inch blade height provides enhanced stability to deliver straight, precise cuts.
  • Clean Finish: 0-degree hook angle ensures clean cuts in both ferrous and non-ferrous sheet metal.
  • Aggressive Tilt: 3-degree tilt angle enhances cutting speed for faster material removal.

Pro-Tip: Purchasing in bulk not only saves money but ensures you aren't caught without a fresh blade mid-project. For the cleanest cuts in metal pipe, start your cut slowly to establish a groove, then increase speed while maintaining steady pressure to prevent the blade from bouncing.
