The HEX-9 HardCeramic drill bit has a centring tip to help you start drilling with precision and without damaging the tile. You need to apply more pressure when drilling with the carbide-tipped HEX-9 HardCeramic drill bits than you need when drilling with diamond-tipped drill bits. You need to have some experience drilling with diamond-tipped drill bits to avoid damaging the drill bit and the tile. Make sure you apply sufficient, but not excessive pressure (15-20 kg is recommended). You should hear a scraping or screeching noise when the drill bit starts removing the material. This normally confirms you’ve applied the right amount of pressure, the drill bit is working correctly and you can carry on drilling.

Always set your power tool to the rotary mode only. Never apply the impact mode, as using this mode will damage the drill bit and the tile. You should set your power tool to gear 1 to prevent the drill bit from overheating.The HEX-9 HardCeramic drill bit offers fast drilling progress in hard tile when compared with other carbide-tipped drill bits, but, in general, diamond drill bits are even faster.

The HEX-9 HardCeramic drill bits offer a great value in absolute cost and an attractive price per hole. Today, a huge range of different types of masonry and concrete drill bits exist for various types of work and materials. At Bosch, we offer a new generation of these drill bits with the new EXPERT product range. The EXPERT SDS plus-7X concrete bits for hammer drills is suitable for drilling soft and hard stone, concrete. The SDS Max-9 CoreCutter for reinforced concrete is a masonry drill bit used for cutting deep holes when installing switch boxes. Diamond drill bits don’t have a centring point and you need to have some experience to start holes exactly where you need them. The carbide-tipped HEX-9 HardCeramic drill bit won’t get damaged easily in case you occasionally touch the material under the tile. Bosch Professional concrete and masonry core bits are designed for use as bits for rotary hammer drills, rotary drill drivers, and impact drivers. Offering superior durability thanks to a range of Bosch technologies, these construction consumables last longer, providing high levels of longevity even when boring through hard materials over a long period of time.Adding a little bit of ‘wobbling’ motion when drilling in hard tiles can help you gain speed and extend the drill bit’s lifetime.

The HEX shank ensures a strong connection and maximum torque transmission from your machine to the drill bit.
