Spiral cutting drill bit Bosch 2 608 585 597

The Bosch 2 608 585 597 spiral cutting drill bit is a single 5 mm diameter bit engineered for use with rotary hammers. Designed for accurate and efficient drilling, it suits a range of materials commonly encountered in construction and renovation. The bit is supplied in a polybag with a hanging hole for convenient storage and handling.

Advantages

The spiral cutting profile improves chip evacuation and reduces clogging during continuous drilling. Precision ground tip geometry supports accurate centring and minimises walking at the start of a hole. Built from hardened steel, the bit delivers wear resistance and consistent cutting performance under typical rotary hammer conditions. The compact 5 mm diameter provides versatility for pilot holes, anchor installation and tasks that require a small-diameter, high-precision hole.

Suitable for

• Drilling small-diameter holes in concrete and masonry with a rotary hammer
• Creating pilot holes for anchors, dowels and fasteners
• Renovation tasks where precise 5 mm holes are required
• Professional and DIY projects needing a durable, single-use spiral cutting bit

Key specifications

• Diameter: 5 mm
• Shank type: compatible with rotary hammer chucks
• Design: spiral cutting geometry for improved chip removal
• Material: hardened steel suitable for masonry drilling
• Packaging: single bit in a polybag with hanging hole

How to use

Install the drill bit securely into the rotary hammer chuck according to the tool manufacturer's instructions. Select the appropriate rotary hammer mode for masonry drilling and set the correct rotational speed and impact settings for a 5 mm bit. Begin drilling with steady axial pressure, allowing the spiral cutting flutes to evacuate debris. Periodically withdraw the bit to clear accumulated dust and prevent overheating. After use, clean the bit and store it in its polybag or a suitable bit holder to protect the cutting edges.

Usage recommendations

Use proper personal protective equipment such as safety glasses and hearing protection. For efficient results in harder masonry, apply consistent pressure and avoid excessive side load. Replace the bit when wear affects drilling accuracy or increases required feed force.
