This Bosch masonry drill bit set (part no. 2608597709) contains 3 drill bits measuring 5mm, 6mm and 8mm in diameter.These are straight shank bits, compatible with all non-SDS impact drills, and part of the "Silver Percussion" line. They are suitable for drilling holes up to 350mm deep in concrete, masonry, limestone, and both natural and artificial stone, and features a special U-shaped flute to effectively prevent clogging caused by drilling dust. They are both impact- and bend-resistant TCT bits, with much longer lives in concrete than other bits on the market.
All Bosch drill bits are manufactured to the highest standard (ISO 5468), which creates a robust bit for drilling quality holes.
