Spiral cutting drill bit Bosch 2 608 585 600 5.5 mm

The Bosch 2 608 585 600 spiral cutting drill bit with a 5.5 mm diameter is engineered for precise, efficient drilling with standard drills and rotary hammers. Its spiral cutting geometry supports smooth chip evacuation and steady penetration through a range of common materials, delivering consistent hole quality for professional and DIY tasks.

Advantages

The spiral cutting design improves chip removal and reduces clogging during continuous drilling. A 5.5 mm diameter offers a balance between strength and accuracy for medium-diameter holes. The bit is manufactured to tight tolerances to provide repeatable hole size and straight runs, while its fluted profile helps maintain drilling speed and reduce heat buildup. Compatibility with standard drill chucks and rotary hammer tool interfaces allows versatile use across different power tools.

Suitable for

• Drilling holes in wood for dowels, screws and fittings
• Creating pilot holes in soft and hard plastics
• Making clearance or bolt holes in light metals and alloys
• General-purpose drilling tasks with handheld drills and rotary hammers

Key specifications

• Diameter: 5.5 mm
• Cutting geometry: spiral/fluted design for chip evacuation
• Intended tool types: drills and rotary hammers (chuck compatibility required)
• Typical applications: wood, plastics, light metals
• Construction: high-precision ground/fluted steel design for straight drilling

How to use

Secure the drill bit in the tool chuck or appropriate rotary hammer adaptor, ensuring the shank is fully seated and tightened. Select a suitable drilling speed and feed pressure for the material—lower speeds for metals and higher speeds for wood and plastics. Begin drilling with steady, even pressure and allow the spiral flutes to evacuate chips; periodically withdraw the bit for deeper holes to clear debris and prevent clogging. After use, clean chips from the flutes and store the bit in a protective case to preserve cutting edges.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves when drilling. Match drilling speed and feed to the material to extend tool life. For precise diameter holes, mark the drilling point and consider a center punch for harder materials. Replace the bit if cutting performance degrades or if visible wear is present.
