Bosch HS1427 Sds Plus Flat Spade Chisel 2.5x10 in Concrete

Product Description

The ROBERT BOSCH TOOL GROUP HS1427 is a flat spade chisel designed for SDS Plus rotary hammers, built specifically for material removal applications in concrete. Measuring 2.5 inches wide by 10 inches in length, this Bulldog Extreme chisel features bracing ribs that increase stability during aggressive chipping work and an optimized overall length that improves handling in confined or tight spaces. A proprietary heat treat process contributes to a self-sharpening edge, reducing downtime between tasks. The double-length spade design extends service life compared to standard chisel configurations, and the geometry delivers a 30 percent higher removal rate versus a conventional chisel. Licensed trades and concrete demo crews are the primary installers.

This chisel is suited for residential and light commercial concrete demolition and material removal tasks where an SDS Plus rotary hammer is the tool of choice. Typical applications include breaking up concrete slabs, removing mortar, stripping tile adhesive, and chipping concrete in utility corridors or mechanical rooms where space is limited. The flat spade profile is especially effective for horizontal surface removal and clean break lines in concrete substrates.

Installation Notes

Installation of SDS Plus chisels should be performed by qualified tradespeople familiar with rotary hammer operation. Before inserting or removing the chisel, power down the tool and disconnect it from its power source. Insert the shank fully into the SDS Plus chuck until it locks, and confirm retention before operation. Eye protection, hearing protection, and appropriate PPE are required during concrete chipping work per applicable job-site safety requirements.
