## Long description

The Bosch 2 609 255 404 diamond drill bit 5.5 mm is engineered for precise holemaking in hard and brittle materials. Intended for use with hand-held drills and drill stands, this 5.5 mm diamond-tipped bit provides controlled, clean drilling performance and extended life compared with standard bits. The product is supplied in a blister pack and features a grey finish on the shank for easy identification.
Advantages

The 5.5 mm diameter ensures predictable hole size for fittings and anchors. The blist er packaging protects the bit during storage and transport and keeps the cutting tip safe until use. The bit’s construction balances durability with chip evacuation to reduce clogging and maintain drilling speed.

Key specifications
Diameter: 5.5 mm
Tip: diamond-coated for cutting hard, brittle materials
Use: designed for drilling ceramics, glass, porcelain, tiles and similar materials
Shank colour: grey
Packaging: blister pack
How to use
Secure the diamond drill bit in a drill chuck suitable for the shank size and set the drill to a low to moderate speed. For best results, use a steady, light pressure and keep the bit perpendicular to the work surface. When drilling glass, ceramic or tiles, it is recommended to use water or a coolant to reduce heat and prolong bit life; apply water continuously to the drilling area while progressing slowly through the material. Start with a small pilot indentation if necessary to prevent the bit from wandering, then continue drilling evenly until the hole is complete.
Usage recommendations
Use protective eyewear and gloves when drilling. Avoid excessive force and high speeds that can overheat the diamond layer. For thicker materials, progress gradually and ensure continuous cooling. Match the 5.5 mm diameter to the intended fastener or fixture to achieve a secure fit.
