Drill bit Smart SDS-plus Duo 16 x 250/200 mm

Drill bit Smart SDS-plus Duo 16 x 250/200 mm is a carbide-tipped masonry drill designed for hammer drills with an SDS-plus shank. The overall length is 250 mm with a working length of 200 mm, making it suitable for drilling medium-depth holes in concrete, brick and natural stone. The SDS-plus connection ensures a secure fit in compatible rotary hammer tools and efficient transfer of percussive energy for faster drilling in hard materials.

Advantages

The Smart SDS-plus Duo 16 x 250/200 mm features a robust flute geometry and carbide tip that improve dust evacuation and extend tool life under sustained percussive use. Its hardened SDS-plus shank provides reliable engagement with rotary hammer chucks to reduce slippage during heavy-duty operation. The combination of 250 mm overall length and 200 mm working length offers a balance between reach and rigidity for accurate, straight holes.

Suitable for

• Drilling anchor and fixing holes in concrete and reinforced concrete
• Creating holes for installation in masonry and brick walls
• Drilling through natural stone and blocks on construction sites

Key specifications

• Drill diameter: 16 mm
• Overall length: 250 mm
• Working length (usable length): 200 mm
• Shank type: SDS-plus
• Tip material: carbide
• Intended materials: concrete, masonry, stone

How to use

Fit the Smart SDS-plus Duo drill bit into an SDS-plus compatible rotary hammer until it locks. Select a percussive drilling mode appropriate for concrete or masonry and start drilling at low speed to create a guide recess, then increase speed and maintain steady axial pressure. Periodically withdraw the bit to clear dust and debris from the hole and the flutes to maintain efficient cutting. For through-holes, ensure clamping of the workpiece where practical and check alignment throughout the operation.

Usage recommendations

Use personal protective equipment such as safety glasses, hearing protection and dust mask when drilling. For reinforced concrete, use controlled pressure and avoid excessive lateral forces to protect the carbide tip. Match drill diameter to recommended anchor or fixing size and ensure the rotary hammer is rated for SDS-plus accessories.
