Bosch is extending its range of saber saw blades with carbide technology with the addition of three new problem solvers: “Endurance for Vehicle Rescue”, “Endurance for Heavy Metal” and “Endurance for Window Demolition”. All blades have individually welded carbide teeth which are extremely wear-resistant and prove themselves even in the toughest applications. They can cut high-strength and ultra-high-strength steel and offer a significantly wider range of applications along with new areas of use which conventional bi-metal blades have so far been unable to cover. At the same time, the new blades have a life-time which is up to 20 times longer than bi-metal saw blades.

With a thickness of 1.35 or 1.25 mm they are 50 or 40 percent thicker than comparable saw blades and, thus, particularly strong. Their carbide technology ensures that this stability is accompanied with high flexibility: Since only the very front tooth tips are made of carbide, the saw blade remains flexible and can withstand bending loads, for example in demolition applications.

 

Quick and reliable

The “Endurance for Vehicle Rescue” saber saw blade – available in two different lengths – was specially developed to meet the requirements of the life-saving services provided by the fire department, rescue workers and the Federal Agency for Technical Relief (Technisches Hilfswerk) on the one hand, as well as those of car dismantlers on the other hand. It cuts through A, B and C pillars made from high-alloy steel, car roofs made from metal sheet, door hing-es as well as windshields made from coated glass quickly and safely. The new blade geometry has several additional benefits: Thanks to the V-shaped tip, the saber saw blade is easier to guide and does not get stuck in the material. The first tooth on the blade is also designed so that the saw blade can plunge directly into the material to be cut without the need for any time-consuming pre-drilling. The saw blade also has a conical shape. As it is narrower at the front than at the rear, it enables access to tight spaces that can often not be reached using hydraulic rescue equipment.

Precision in the toughest applications

The benefits of “Endurance for Heavy Metal” saber saw blades can be seen, for example, when installing or replacing water pipes and anywhere where high-strength and ultra-high-strength steel, stainless steel or cast iron needs to be cut. With a 25 mm blade, they are 30 percent wider than comparable saber saw blades. This provides more accurate guidance and higher stability when sawing and, thus, a more precise, clean cut. Available in four different lengths, trades-people can use these blades to machine different pipe and railing diameters or cut through locks.

 

One blade for many materials

The “Endurance for Window Demolition” saber saw blades can cut through window frames with a steel core or those made from different materials such as wood, aluminum and plastic, as well as remove hardened window screws, without having to change the blade. The constant tooth pitch across the entire blade means that window fitters can cut different materials quickly and reliably. And if the tradesperson accidentally comes into contact with plaster, mortar or bricks when carrying out this work, the blades can handle it with ease. In order to keep vibrations to a minimum in all applications, the length of the blades was optimized at 150 mm. Beyond that, the “Endurance for Window Demolition” saw blades have a conical shape. They are narrower at the front than at the rear and can, therefore, also be used in tight spaces.
