Vrták Bosch SDS plus-7X 16 x 550 mm na rotačné a príklepové vŕtanie

Bosch SDS plus-7X 16 x 550 mm drill bit is engineered for rotary and hammer drilling in concrete, masonry and natural stone. With a 16 mm diameter and a long 550 mm overall length, this bit enables deep-hole drilling for tasks such as anchor installation, through-holes for services and renovation work. The SDS plus-7X geometry and flute design promote efficient dust and debris removal while maintaining reliable impact performance in professional and DIY applications.

Advantages

The SDS plus-7X design offers enhanced drilling speed and improved chip evacuation compared with standard bits. Its optimized flute profile reduces clogging during deep drilling while the robust head geometry ensures consistent impact transfer and long service life. The 550 mm length allows reaching recessed or deep positions without extensions, and the 16 mm diameter provides a commonly used size for medium anchoring and through-hole requirements.

Suitable for

• Drilling deep holes in concrete and reinforced concrete
• Creating through-holes for plumbing, electrical or HVAC routes
• Anchor and dowel installation in masonry and stone
• Renovation and construction work requiring extended reach

Key specifications

• Shank system: SDS-plus compatible
• Diameter: 16 mm
• Overall length: 550 mm
• Working length: suitable for deep drilling applications
• Recommended drill type: rotary and hammer drills with SDS-plus chuck
• Material application: concrete, masonry, natural stone

How to use

Fit the drill bit into an SDS-plus chuck until it locks securely. Select the hammer drilling mode when working in concrete or masonry, and use rotary mode for softer stone or precise positioning. Start drilling at low speed to establish the hole and then increase speed while maintaining steady, moderate pressure; avoid excessive force to prevent premature wear. Withdraw the bit periodically to clear dust and allow the flutes to evacuate debris, which helps maintain cutting efficiency and reduces heating.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a dust mask. Match the drill bit with a hammer drill that supports SDS-plus shanks and follow manufacturer guidelines for impact energy and speed ranges. For reinforced concrete, consider core positioning and rebar avoidance; if rebar is encountered, stop and assess or use a dedicated rebar-cutting solution.
