Punta Bosch Expert HEX-9 Multi Construction 6,5 mm

Bosch Expert Hex-9 Multi Construction drill bit, 6.5 mm diameter, is a purpose-made cutting tool for creating reliable holes in a range of common building materials. The bit features a Hex-9 shank that provides a secure fit in compatible chucks and bit holders, reducing slippage during drilling. Designed for multi-construction use, the geometry and cutting edges are optimized to deliver consistent 6.5 mm holes for both professional tasks and DIY projects.

Advantages

The Hex-9 shank ensures stable retention in hex-compatible holders, improving torque transfer and reducing wobble. The drill tip and flute design facilitate efficient debris evacuation and steady progress through materials typically encountered on construction sites and home renovation jobs. Built to provide repeatable hole quality, the bit balances durability with cutting performance for frequent use at the 6.5 mm size.

Suitable for

• Drilling 6.5 mm holes in wood and plywood
• Drilling into masonry and concrete with appropriate pilot techniques
• Working with gypsum board, plaster and composite building panels
• General installation tasks such as fixing anchors, dowels or running conduit
• Portable drilling with impact drivers and compatible hex chucks

Key specifications

• Diameter: 6.5 mm
• Shank type: Hex-9 for secure bit holder/chuck engagement
• Application: Multi-construction/general building materials
• Intended use: Professional and DIY drilling tasks
• Compatibility: Compatible with hexagonal chucks and bit holders designed for a 9 mm hex shank

How to use

Select an appropriate drill or impact driver with a hex-compatible chuck or bit holder and insert the Hex-9 shank fully until it seats securely. Mark the drilling point and, where needed, clamp or support the workpiece to prevent movement. Begin drilling at low speed to establish the hole, then increase speed and apply steady pressure according to the material. For masonry or concrete, use a hammer-drill or impact mode and consider a pilot hole or the correct masonry procedure. Withdraw the bit periodically to clear debris and avoid overheating.

Recommendations

Use personal protective equipment such as safety glasses and gloves. Match drilling speed and feed pressure to the material: lower speeds for masonry, moderate speeds for metals and higher speeds for wood. Inspect the bit before use for wear or damage and replace when cutting performance declines to maintain hole accuracy and safety.
