Drill bit GRAPHITE SDS MAX 28 mm for concrete, model 57H532

GRAPHITE SDS MAX 28 mm drill bit for concrete, model 57H532, is a masonry bit designed for use with SDS MAX rotary hammers. With a 28 mm working diameter, this bit is intended for drilling through concrete, reinforced concrete and other masonry materials where larger-diameter holes are required for anchors, dowels and installations. The bit’s shank fits SDS MAX chucks and its construction is optimized for percussion drilling in demanding building and renovation tasks.

Advantages

The drill bit provides stable drilling performance in dense materials due to its robust carbide tip and reinforced flute design, which improves chip removal and reduces jamming. Its SDS MAX shank ensures secure retention in compatible rotary hammers and allows quick tool changes. The bit’s length and profile support deep-hole drilling while minimizing bending and wear under heavy loads.

Suitable for

• Drilling anchor and dowel holes in concrete and reinforced concrete
• Creating openings for plumbing, electrical installations and pipework routes
• Renovation and construction tasks requiring larger diameter holes (28 mm)
• Use with SDS MAX rotary hammers on building sites and in professional workshops

Key specifications

• Diameter: 28 mm working diameter suitable for larger anchor holes
• Shank type: SDS MAX compatible for secure retention in rotary hammers
• Intended material: concrete, reinforced concrete and masonry
• Tip: carbide-tipped for improved wear resistance and efficient percussion drilling
• Flute design: reinforced for improved dust and debris removal during drilling

How to use

Install the bit into an SDS MAX rotary hammer according to the tool manufacturer’s instructions, ensuring the shank locks securely. Select hammer-drilling mode when working in concrete or masonry, apply steady axial pressure without excessive force, and allow the tool and bit to do the work. For deep holes, periodically withdraw the bit to clear debris and prevent overheating. Use appropriate personal protective equipment such as eye protection, hearing protection and dust masks when drilling.

Usage recommendations

For best results, match drill speed and hammer settings to the material and hole depth, use water extraction or dust extraction systems where available to reduce dust, and replace the bit when signs of excessive wear or dulling appear. Ensure compatibility with your rotary hammer’s SDS MAX system before use.
