Dehaco DHB2000S Dust Grooved, Hard Rock Chisel Tool

A: The Dehaco DHB2000S dust grooved, hard rock chisel tool is made for the Dehaco DHB2000S hydraulic breaker: diameter 135 mm, overall length 1200 mm, weight 135 kg. Just state your breaker brand and model when you order.

A: Not always. The position and shape of the retaining pin slot change with brand and model; a tool with the same diameter and length may not fit. This tool is made to the slot dimensions of the Dehaco DHB2000S.

A: The Dehaco DHB2000S dust grooved, hard rock chisel tool is mainly used for: primary demolition, secondary demolition, trenching, recycling, scaling, primary breaking, boom mounted applications. According to the material table in our manual, it is recommended for reinforced concrete slabs, walls, columns and foundations, heavily fractured rock, asphalt and frozen ground.

A: The dust grooves guide dust and fine particles away from the breaking zone. Visibility and precision improve, tool wear and heat build-up drop, and the tool keeps its performance longer.

A: The hard rock version is made from a high-nickel alloy and goes through a special hardening process. It withstands extreme impact forces and abrasive rock, and is the preferred choice for heavy quarrying and mining. For general demolition and construction the standard tool is enough.

A: We make 14 different tools for the Dehaco DHB2000S: moil point tools, chisel tools, pyramid tools, blunt tools, with dust grooved and hard rock options. You can reach all of them from the Other Tool Types table on this page.

A: Like all HKM breaker tools, the Dehaco DHB2000S dust grooved, hard rock chisel tool is warranted against manufacturing defects only. The fracture surface is examined; if the fracture started from a flaw inside the material, the tool is covered. Breakage from prying, blank firing, rotating the embedded tool or working with worn bushings is not covered.

A: Prying before the tool is fully seated, blank firing, striking one spot for too long, insufficient or wrong grease, and working with worn bushings. On a chisel, twisting also wears the retaining pin slots.

A: Compare the inner diameters of the lower and upper bushings and the thrust bushing surface with the tolerances in your breaker's service manual. Worn bushings move the tool and piston off axis.

A: It is also called “wedge”, “wedge tool”, “flat chisel”, “dust chisel”, “DEG chisel”. Breaker tools in general are also known as breaker chisels, working tools or hammer tools.
