Drill bit Bosch CYL-9 5 mm x 70 mm, 1 pc

Bosch CYL-9 5 mm x 70 mm drill bit is designed for accurate drilling in soft to medium-density tiles, porcelain, ceramics and non-toughened glass. Supplied as a single piece, this 5 mm diameter bit with a 70 mm length fits standard drills with a cylindrical shank and is intended for general-purpose drilling, fittings installation and repair work where controlled, non-impact drilling is required.

Advantages

The drill bit offers precise 5 mm holes with a white stainless-steel body and a cylindrical shank for stable clamping in drill chucks. Its geometry and material make it suitable for brittle surfaces without causing excessive chipping when used at low speeds and without impact. Delivered as one piece, it is convenient for occasional jobs and small installations.

Suitable for

• Drilling holes in soft ceramic wall tiles and soft tiles
• Creating openings in porcelain and unhardened glass for light fittings
• Installing bathroom and kitchen fixtures in tiled surfaces
• Repair work where precise small-diameter holes are needed

How to use

Secure the Bosch CYL-9 drill bit in the drill chuck by tightening the cylindrical shank firmly. Position the bit perpendicular to the work surface and start drilling at low speed, applying steady, light pressure. Do not use impact mode. For brittle tiles and glass, begin with a small pilot mark or tape to prevent slipping and proceed slowly until the hole is complete. No external cooling is required for these materials when using the recommended low-speed technique.

Usage recommendations

Use low rotational speeds and avoid hammer/impact settings. For best results on tiles and glass, start drilling with a steady hand, consider using masking tape to reduce skidding, and replace the bit when wear or chipping reduces precision.
