Description

The ROBERT BOSCH TOOL GROUP T141HM1 is a T-shank jig saw blade engineered for cutting fiberglass and plaster. At 4 inches in length with a 6 TPI carbide edge, this blade is built to handle abrasive materials that quickly destroy standard bi-metal or high-speed steel blades. The carbide edge retains its cutting geometry significantly longer in hard, gritty substrates, reducing blade change frequency on demanding jobs. Sold in a pack of 5, the T141HM1 is a practical choice for trade professionals who encounter fiberglass duct board, fiberglass panels, or plaster walls regularly.

This blade is suited for residential and light commercial applications where fiberglass and plaster materials are common. Typical install or service scenarios include cutting fiberglass duct liner, HVAC air handler enclosures, plaster wall access panels, and fiberglass reinforced plastic panels. The T-shank interface provides a tool-free blade change on jig saws equipped with a universal T-shank chuck, which is standard on the vast majority of modern jig saw models. Each pack contains 5 blades, making it convenient to keep spares on the truck or job site.

Installation Notes

Installation of this blade is performed by the tool operator power down and unplug or battery-disconnect the jig saw before changing blades. Insert the T-shank into the chuck until it seats fully and the retention mechanism engages. Inspect the blade for damage before each use and replace immediately if carbide teeth show chipping or the blade body shows signs of bending. Eye and respiratory protection are recommended when cutting fiberglass due to airborne particle hazards.
