Robert Bosch Tool Group BM2003 Masonry Drill Bit 5 Pack

Product Description

The ROBERT BOSCH TOOL GROUP BM2003 is a fast spiral rotary masonry drill bit engineered for drilling into masonry, block, and brick using a standard rotary drill. The 3/16-inch diameter bit has a 2-inch usable length and 4-inch overall length. A double flute design accelerates material removal while a carbide head provides long service life in demanding masonry applications. Precision manufacturing reduces bit walking at the start of the hole. This bit is optimized for high-speed cordless rotary drill operation and is sold in a pack of five.

The BM2003 is intended for residential and light commercial masonry work where a rotary drill is the available tool. Typical applications include anchor and fastener pilot holes in concrete block, brick, and similar masonry substrates. Installers in HVAC, plumbing, electrical, and general construction trades use bits of this type when routing penetrations or securing equipment to masonry walls and floors. This bit is designed strictly for rotary drilling mode and must not be used in hammer drill mode.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with masonry drilling practices. Verify the drill is set to rotary-only mode before use — engaging hammer mode with this bit may cause bit failure or injury. Eye protection and dust control measures are recommended when drilling masonry. Confirm no embedded rebar, conduit, or utilities are present in the work area before drilling.
