Maximize Metal Cutting Speed and Durability

The Bosch RM618 6-Inch 18 TPI Metal Reciprocating Saw Blade 5-Pack is engineered to deliver professional-grade performance in demanding metal cutting applications. Constructed with premium bi-metal materials, these blades feature a flexible 0.035-inch thin-kerf body that resists breakage while providing the rigidity needed for straight, accurate cuts. The optimized 3/4-inch blade height further enhances stability, ensuring you get clean results whether you are cutting ferrous or non-ferrous sheet metal (10–16 gauge), pipes, or structural profiles.

What sets the RM618 apart is its specialized tooth geometry. The reinforced "pair-setting" design—featuring two teeth facing left followed by two teeth facing right—clears chips efficiently for faster cutting speeds and extended blade life. With a 3-degree tilt angle for aggressive engagement and a 0-degree hook angle for smooth finishes, these blades are the reliable choice for contractors needing consistent performance on the job site. Designed to fit all standard reciprocating saws, this pack ensures you are always ready for the next cut.

Key Features

  • Bi-Metal Construction: Delivers a durable cutting edge with outstanding toughness for long life in metal.
  • Pair-Setting Geometry: Unique tooth arrangement (2 left, 2 right) optimizes speed and chip clearance.
  • Sheet Metal Specialist: 18 TPI design is ideal for clean cuts in 10–16 gauge ferrous and non-ferrous metals.
  • Flexible Body: 0.035-inch thin-kerf body allows for accurate cuts, easier starts, and reduced breakage.
  • Precision Cutting: 3/4-inch blade height provides superior stability for straight, controlled cuts.
  • Aggressive Angle: Features a 3-degree tilt angle for faster cutting action through tough materials.
  • Clean Finish: 0-degree hook angle ensures smooth edges on sheet metal and pipes.

Pro-Tip: When cutting metal with a reciprocating saw, friction is your biggest enemy. To extend the life of your blade significantly, lower the speed of your saw (trigger control or dial) and apply a small amount of cutting oil or lubricant to the cut line. This keeps the teeth cool and prevents them from dulling prematurely.
