Bosch MP03 Multi-purpose Drill Bit 3/16 X 6 Inch Hex Shank

Product Description

The ROBERT BOSCH TOOL GROUP MP03 is a multi-purpose drill bit designed for trade professionals who need to move through multiple materials without swapping bits. Measuring 3/16 inches in diameter with a 6-inch overall length and a 4-inch flute length, this bit features an upgraded multi-grind head that delivers up to 85% faster drilling in metal compared to standard bits. The 1/4-inch hex shank is impact rated, making it compatible with both impact drivers and hammer drill/drivers. A no-skate tip design reduces wander on hard surfaces, producing cleaner entry holes across a range of substrates.

The MP03 is built for multi-application use in residential and commercial jobsite environments. It drills through masonry, brick, block, tile, metal, wood, and plastic, making it well suited for electricians, plumbers, and HVAC installers who routinely penetrate mixed-material assemblies. Long-life construction is rated for up to 9x the service life in multi-material applications compared to standard bits, reducing the frequency of bit changes on demanding jobs.

Installation Notes

Installation and use of this bit is appropriate for licensed electricians, plumbers, HVAC technicians, and other trade professionals performing rough-in or penetration work.

When drilling into masonry or block, use hammer mode where available and maintain consistent pressure to avoid bit binding.
