Drill Bits: Bosch Mortar Knife

Mortar removal between sensitive brick, block and stone can be a difficult and time-consuming task, even for the seasoned pro. But masons, contractors and architects just got some tuckpointing relief with the introduction of the Bosch mortar knife, a mortar-removal tool for SDS-plus rotary hammers that's both more precise and faster than any current mortar-removal options that include flat chisels not optimized for tuckpointing applications.

The knife's Precision Plunge Tip is based on a unique design that combines a blunt point with a sharpened knife edge. It has an 8-inch working length that allows it to plunge deep into mortar while a sharp straight edge cuts away debris quickly and easily without jamming.

Mortar knife widths of 1/4-inch and 3/8-inch ensure precise fit between brick, block and stone - with a reduced risk of damage.

"The mortar knife works like a conventional knife so the precision is great. That's important when the project involves expensive stone or brick, or a historic facade that cannot be replaced," said Matt Van, product manager, concrete accessories, Bosch. "No company has ever adapted this centuries-old knife design to tuckpointing in renovation and construction. The combination of accuracy and speed cannot be beat."

The Bosch mortar knife is faster in debris removal thanks to a cutting action that can be used from more angles than a plug chisel. The sharp edge of the tool crushes mortar and then removes it quickly and it won't leave extra "half-moon" material in the head joint like a diamond blade.

Product life is extended thanks to use of superior induction-hardened materials and a blunt tip that's not susceptible to breakage.

The mortar knife is built for SDS-plus hammers for maximum power transfer.
