Drill bit Bosch 6.5 mm spiral cutting (1 pc) model 2 608 597 778 for drills and rotary hammers

Bosch spiral cutting drill bit 6.5 mm (single piece) model 2 608 597 778 is a carbide-tipped spiral bit designed for drilling precise 6.5 mm holes with both handheld drills and rotary hammers. The spiral cutting geometry ensures efficient chip evacuation and steady drilling performance in common building materials. This single-piece supply is suitable where an exact 6.5 mm hole is required for installation, fastening, or repair tasks.

Advantages

The spiral cutting design improves material removal and reduces clogging during continuous drilling. A precisely ground tip and flutes provide stable guidance and consistent hole quality. The bit is compatible with standard drill chucks and rotary hammer tool interfaces, offering reliable performance for repetitive drilling operations. Its single-piece packaging makes it convenient for on-site replacement and inventory control.

Suitable for

• Drilling 6.5 mm holes in masonry, concrete, and brick where the spiral geometry aids chip removal
• Installation of anchors, dowels, and fasteners requiring a 6.5 mm bore
• Repair and retrofit tasks on construction sites and in mechanical installations
• Use with handheld drills and rotary hammers for general-purpose drilling

Key specifications

• Diameter: 6.5 mm
• Design: spiral cutting flutes for efficient chip evacuation
• Quantity: single piece
• Compatibility: suitable for drills and rotary hammers with standard chucks or tool-specific holders
• Application: drilling holes for anchors, fasteners, and general construction tasks

How to use

Secure the drill bit in the tool chuck or holder according to the drill or rotary hammer manufacturer instructions, ensuring the bit is firmly seated. Select an appropriate drilling mode and speed for the material being worked on; use rotary hammer mode for harder masonry and concrete. Apply steady axial pressure without forcing the bit; allow the spiral flutes to evacuate chips naturally. Withdraw the bit periodically when drilling deep holes to clear debris and prevent overheating. After use, clean the flutes and store the bit in a dry place.

Usage recommendations

Use suitable personal protective equipment such as eye protection and gloves. For best results in reinforced concrete, verify rebar location before drilling and adjust technique or tool settings as needed. Replace the bit when wear causes poor cutting performance or oversized holes.
