Bosch CYL-9 Ceramic Tile Drill Bit

According to the product description, it is optimized for marble surfaces and various types of marble, with applicability to ceramic tile contexts as well. It’s built to provide clean holes with minimal chipping in marble-like materials and ceramic tile surfaces.

The CYL-9 is one size in Bosch’s ceramic tile/marble drill-bit lineup. Bosch typically offers multiple diameters (for example 6 mm, 8 mm, 10 mm, etc.) within this family. To find the exact available sizes, check the product options on the Fepy listing for this bit and its related variants.

Tips for best results: use a low to moderate RPM drill with steady, light-to-moderate pressure; keep the bit cool with water or a brief spray to reduce heat and dust; start with a pilot mark and a shallow pilot hole if needed; avoid forcing the bit through material and let the bit do the work at a controlled pace.

It’s carbide-tipped, which provides high hardness and wear resistance. The bit’s optimized tip design is intended to cut cleanly with reduced vibration and less debris build-up, contributing to a longer service life when drilling marble and tile.

Wear safety glasses to protect your eyes from chips, secure the workpiece with clamps, use a lower speed to control the cut, apply even, gentle pressure, and keep the work area well ventilated. Cooling the bit with water during drilling helps prevent overheating and prolongs tool life.

Compared to other ceramic tile/marble bits on Fepy, the CYL-9 emphasizes a carbide tip and an optimized tip design for marble-friendly penetration. For alternatives, you can explore other Bosch cylinder-style tile bits such as the CYL-8 and CYL-10 to suit different diameters and project needs.

Ideal projects include drilling holes in marble countertops, marble backsplashes, and other marble surface installations where a clean hole with minimal chipping is important. It’s also suitable for ceramic tile work where a precise, smooth bore is desired.

Use this bit in a standard drill (corded or cordless) at low to moderate speed. Do not use hammer or impact settings, as those can damage the bit or the tile/marble surface. Let the bit do the cutting with controlled pressure and lubrication cooling as needed.

Clean off any dust and debris after use, lightly oil or wipe the carbide tip if recommended by Bosch, and store in a dry, secure case or organizer to protect the tip from impact. Keeping it dry and protected prevents corrosion and maintains sharpness.

The CYL-9 is designed with a carbide tip and an optimized geometry tailored for marble penetration, potentially delivering cleaner holes with less chipping and longer life in marble work. If you’re drilling marble regularly, this design aims to offer consistent performance alongside Bosch’s reliability.
