Bosch RM1218 12 Inch 18 TPI Metal Reciprocating Saw Blades 5 Pack Bi-Metal Flexible Body for Ferrous Non-Ferrous Sheet Metal

ACHIEVE PROFESSIONAL PRECISION IN THIN METAL CUTTING

Maximize your efficiency on the job site with the Bosch RM1218 12-Inch 18 TPI Metal Reciprocating Saw Blades (5-Pack). Designed specifically for professional contractors and demanding metalworkers, these blades feature a robust bi-metal construction that delivers exceptional life and durability. The innovative "pair-setting" tooth geometry—where two teeth face left followed by two teeth facing right—is optimized for speed, providing fast, clean cuts in ferrous and non-ferrous sheet metal ranging from 10 to 16 gauge. Whether you are cutting ductwork, steel studs, or metal piping, these blades ensure a long service life and reliable performance.

Engineered for flexibility and strength, the RM1218 utilizes a thin 0.035-inch kerf body that resists breakage while allowing for easier starts and accurate cuts. The standard 3/4-inch blade height provides the stability needed for straight cuts, preventing the wandering often associated with thinner blades. By combining high-quality materials with job-site proven design elements like a 0-degree hook angle and a 3-degree tilt angle, Bosch delivers a reciprocating saw blade that cuts faster, lasts longer, and handles the toughest metal cutting challenges with ease.

Specifications

Pro-Tip: The "3-tooth rule" is essential for preventing blade snagging and breakage. When cutting thin metal, ensure that at least three teeth are in contact with the material at all times. Since this blade has 18 TPI, it is best suited for metals thicker than 1/8 inch. If you hear excessive chatter or vibration, the metal may be too thin for the blade, or your speed is too high.
