Bosch CYL-9 Ceramic Tile Drill Bit - 5 x 70mm

No, this bit is designed for use with non-impact drills only. Using it with the hammer function engaged will likely damage the bit and the material.

This bit is suitable for soft to medium-hard ceramic tiles. It is not recommended for porcelain, natural stone, or hardened tiles.

No, the CYL-9 Soft Ceramic Tile Drill Bit is designed for dry drilling. No lubrication or coolant is required.

Always use the drill at low speeds. Consult your drill's manual for recommended RPMs, but generally, keep speeds below 1000 RPM for bits of this size.

Use slow, steady speed, minimal pressure, and avoid sudden jolts. Ensure the glass is well-supported and drill away from edges if possible. Practice on a scrap piece first.

The flute-less design is optimized for drilling into brittle materials like tiles and glass, reducing the risk of chipping and providing a cleaner cut compared to bits with aggressive flutes.

CYL-9 refers to Bosch's designation for bits with a cylindrical shank, commonly used in standard drill chucks. It indicates suitability for a wide range of drills.

Ensure the drill is set to a low speed and is not in impact mode. Check if the material being drilled is within the soft to medium-hard range. Sharpen or replace the bit if it appears worn.

Reduce drilling speed and pressure. Allow the bit to cool down between holes. Ensure you are not using the impact function.

Apply less pressure and ensure a low drilling speed. Consider marking the drilling point with tape to help guide the bit and minimize chipping.

This typically occurs from using excessive force, the wrong drill setting (impact mode), or drilling into harder material than the bit is designed for. Inspect your drill settings and material type.
