Punta per trapano Bosch CYL-9, diametro 5 mm, lunghezza 70 mm, singola

The Bosch CYL-9 drill bit with a 5 mm diameter and 70 mm overall length is designed for controlled drilling in soft to medium-density tiles, porcelain, ceramics and non-toughened glass. Supplied as a single piece with a cylindrical shank and white finish, this bit is intended for use in standard drills and drill holders where small, precise holes are required. Its geometry and recommended low-speed, non-impact operation make it suitable for routine tasks that call for clean edges and minimal chipping.

Advantages

The CYL-9 offers a compact 5 mm diameter that enables accurate positioning and reduced material stress during drilling. The 70 mm length provides enough reach for most tile and ceramic applications while keeping the tool stable in the drill chuck. The cylindrical shank ensures compatibility with common drill holders. Designed specifically for softer ceramic surfaces and non-hardened glass, the bit reduces the risk of cracking when used at low speeds without impact.

Suitable for

• Drilling small-diameter holes in soft ceramic wall tiles
• Creating openings in porcelain and soft tile where precision is required
• Working with non-toughened (unhardened) glass for light-duty fixtures
• Routine maintenance and installation tasks that require a 5 mm hole

Key specifications

• Overall length: 70 mm
• Shank type: Cylindrical shank compatible with standard drill chucks
• Compatible materials: Soft ceramic wall tile, soft tile, porcelain, non-toughened glass
• Finish/color: White
• Quantity: 1 piece

How to use

Secure the Bosch CYL-9 drill bit in the drill chuck so the cylindrical shank is held firmly and runout is minimised. Position the drill perpendicular to the work surface and use a low rotational speed. Do not use impact or hammer mode. Apply steady, moderate pressure rather than forceful pushing to allow the bit to cut cleanly and reduce the risk of chipping. No additional cooling is required for the specified materials; however, pausing periodically can help dissipate heat buildup on extended runs.

Recommendations

For best results, start with a small pilot mark or use masking tape to prevent slipping on glazed surfaces. Maintain low drill speeds and avoid impact modes. Inspect the bit for wear before each use and replace it if cutting performance diminishes or chipping occurs.
