Drill Bit Bosch SDS plus-7X 6 x 100 x 165 mm, set of 10

The Bosch SDS plus-7X 6 x 100 x 165 mm drill bit set contains ten identical SDS-plus shank bits designed for hammer drilling in concrete, masonry and natural stone. Each bit has a 6 mm diameter, a 100 mm working length and a 165 mm overall length, making this set suitable for repetitive drilling tasks where consistent hole size and depth are required. The bits are compatible with SDS-plus rotary hammers and are intended for both professional tradespeople and informed DIY users working on construction and renovation projects.

Advantages

The SDS plus-7X design provides fast drilling progress and improved chip removal compared with standard bits, helping to maintain drilling speed during extended use. Hardened tip geometry and a wear-resistant flute profile deliver consistent accuracy and prolonged service life under impact load. The SDS-plus shank ensures secure bit retention and quick bit changes in compatible rotary hammers, reducing downtime on repetitive tasks.

Suitable for

• Hammer drilling into concrete for anchor and fastener installation
• Drilling holes in masonry and brick for through-fixings and dowels
• Creating starter holes in natural stone where controlled diameter is required
• High-volume repetitive drilling on construction and renovation sites
• Use with SDS-plus rotary hammers in professional or DIY applications

Key specifications

• Diameter: 6 mm
• Working length: 100 mm
• Overall length: 165 mm
• Shank type: SDS-plus
• Quantity: 10 pieces per set
• Material and tip design: impact-hardened tip with optimized flute for chip evacuation

How to use

Fit the SDS-plus shank securely into the rotary hammer chuck following the tool manufacturer’s instructions. Select the hammer-drill mode for effective drilling in concrete and masonry. Apply steady axial pressure, allowing the hammer action to perform the cutting; avoid excessive lateral force to prevent premature wear. Periodically withdraw the bit to clear dust and debris from the hole and to prevent clogging, which helps sustain drilling speed and accuracy. Replace worn bits when drilling performance or hole quality degrades.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control measures. Match drill diameters and working length to the required anchor or fastener depth. For reinforced concrete, use appropriate techniques and confirm suitability of the bit for drilling near rebar. Store bits dry and clean to maintain condition between uses.
