Robert Bosch Tool Group PTB4418 Band Saw Blade 18 Tpi 3pk

Product Description

The ROBERT BOSCH TOOL GROUP PTB4418 is a 3-pack of bi-metal portable band saw blades designed for demanding cutting applications across a range of materials. Each blade measures 44-7/8 inches in length, 0.5 inches in width, and 0.02 inches in thickness, with an 18 TPI tooth configuration suited for fine, controlled cuts. The bi-metal construction combines a flexible alloy steel backing with high-speed steel teeth, delivering durability and resistance to blade fatigue during extended use. These blades are installed by electricians, plumbers, HVAC techs, and general contractors who rely on portable band saws for cutting conduit, pipe, strut, and structural material in the field.

These blades are intended for use with common portable band saw platforms and are rated for cutting wood, plastic, and most metals. The 18 TPI count makes them well suited for thinner stock and non-ferrous metals where a finer tooth pitch reduces burring and improves cut quality. They are a practical multi-material option for trade professionals who carry a portable band saw on the job and need consistent blade performance across varying materials and conditions.

Installation Notes

Blade installation and replacement should be performed by a qualified tradesperson familiar with portable band saw operation. Always disconnect or power down the tool before changing blades. Use appropriate blade-handling gloves when removing or installing band saw blades, as tooth edges are sharp. Confirm blade tension and tracking per the tool manufacturer guidelines before resuming cuts.
