Drill Bit GRAPHITE SDS+ 16 mm for Concrete, model 57H472

GRAPHITE SDS+ 16 mm drill bit for concrete, model 57H472, is designed for drilling through-holes and anchor holes in reinforced and non‑reinforced concrete as well as masonry. The bit fits SDS+ rotary hammer systems and features a standard SDS+ shank that enables secure mounting and quick bit changes. Its flute geometry supports efficient removal of dust and debris during hammer drilling, making it suitable for both professional construction work and renovation or installation tasks.

Advantages

The GRAPHITE SDS+ 16 mm drill bit offers reliable compatibility with SDS+ rotary hammers and consistent drilling accuracy in concrete and masonry. Its shank design provides fast and secure bit changes while the optimized flute pattern improves chip evacuation, reducing clogging and maintaining drilling performance. The bit is made to withstand impact drilling stresses typical for anchor and through-hole applications.

Suitable for

• Drilling through-holes and anchor holes in reinforced concrete
• Drilling in non-reinforced concrete and masonry
• Installation of anchors, dowels and fixing systems
• General construction, renovation and fitting tasks requiring 16 mm holes

Key specifications

• Diameter: 16 mm
• Shank type: SDS+
• Intended material: concrete and masonry (reinforced and non-reinforced)
• Application type: hammer drilling for through-holes and anchor holes
• Flute design: optimized for dust and debris removal

How to use

Install the 16 mm SDS+ bit securely into the rotary hammer’s chuck according to the tool manufacturer’s instructions. Select the hammer-drill mode appropriate for concrete. Start drilling at low speed to establish the hole position, then apply steady forward pressure while allowing the hammer action to do the work. Periodically withdraw the bit to clear accumulated debris when drilling deep holes. Use appropriate personal protective equipment, including eye and ear protection and a dust mask.

Usage recommendations

For best results, use the bit with SDS+ rotary hammers sized for concrete work and select the correct drill mode for impact drilling. When drilling reinforced concrete, avoid excessive lateral force and let the hammer function penetrate steel reinforcement carefully; if prolonged drilling is required, withdraw the bit occasionally to clear dust and reduce heat buildup.
