Home improvement accessory built to deliver accurate holes across a range of materials, ideal for tradespeople and keen DIYers. Confident hole placement reduces rework and keeps projects on schedule. Worth choosing for mixed-material work and heavy use on site? The Bosch EXPERT HEX-9 MultiConstruction Drill Bit
⚡ At a Glance
- • Drilling Accuracy: Up to five times more precise than Bosch CYL-3, aided by centring geometry
- • Best for: Tradespeople and DIYers who need precise holes across masonry and domestic materials
- • Not ideal for: Jobs that require large-diameter specialised masonry bits
Hex shank construction ensures strong torque transfer in chucks and 1/4" holders. MultiConstruction design works in impact mode for concrete and stone, and rotary mode for tiles, brick, metal, wood and plastic.
Accurate hole placement - thanks to Bosch Centering Geometry
Bosch Centering Geometry positions the tip to reduce wandering at drill start, improving initial bite and alignment. The cutter profile and tip shape limit lateral movement when entering hard surfaces.
More accurate starts mean fewer misaligned holes and less need for correction. This helps keep trim work and fixtures aligned without extra measuring.
Reliable torque transfer - with hex shank connection
Hex shank design locks into three-jaw chucks and 1/4" internal hex tool holders for a positive mechanical fit. The shape transmits torque efficiently, reducing slippage under load.
Secure grip reduces bit wobble and slippage during heavy drilling, so holes remain true and tools run smoother. That makes work faster and less frustrating on site.
Versatile drilling across materials - thanks to MultiConstruction geometry
Tip and flute geometry support impact mode on concrete and stone, while the rotary setting handles brick, soft ceramic tile, sheet metal, wood and plastic. The bit is sized and shaped for mixed-material performance.
One bit covers a wide range of common building materials, cutting down on bit changes and keeping workflows steady. Ideal for jobs where materials vary from masonry to timber.
