Drill Bit GRAPHITE SDS MAX 24 mm for concrete, model 57H528

GRAPHITE SDS MAX 24 mm drill bit, model 57H528, is designed for drilling into concrete with SDS MAX rotary hammers. The 24 mm diameter and robust flute geometry enable effective removal of concrete dust and chips, allowing for precise, deep holes required for anchors, conduit passages and heavy masonry installations. The shank shape ensures secure engagement with compatible hammer drills, while the bit's length and cutting profile support demanding drilling tasks in reinforced and non-reinforced concrete.

Advantages

The SDS MAX 24 mm drill bit offers consistent drilling performance and optimized chip evacuation to reduce clogging during prolonged use. Its construction provides stable centring and accurate hole diameter, supporting repeatable results in series drilling. The bit is compatible with standard SDS MAX rotary hammers and is suitable for continuous work on concrete surfaces where durability and cutting efficiency are needed.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Creating passages for electrical conduits and plumbing in concrete structures
• Heavy-duty renovation and construction tasks requiring deep, precise holes
• Professional and advanced DIY projects using SDS MAX rotary hammers

Key specifications

• Drill diameter: 24 mm
• Mount type: SDS MAX compatible shank
• Intended material: concrete and masonry
• Flute design: optimized for chip evacuation
• Use case: rotary hammer drilling for deep holes and anchors

How to use

Secure the drill bit in an SDS MAX rotary hammer according to the tool manufacturer's instructions. Mark the drilling point and, if required, start with a lower hammer speed to create a centre indent. Apply steady axial pressure and allow the hammer action and bit geometry to remove material; avoid excessive side loads that can shorten bit life. Periodically withdraw the bit during deep drilling to clear accumulated dust and improve cooling. Use appropriate personal protective equipment, dust extraction or wet drilling methods where applicable.

Usage recommendations

For best results, use the drill bit with a rotary hammer that supports SDS MAX bits and provides adequate impact energy for 24 mm drilling in concrete. Combine with dust extraction or HEPA vacuum systems when drilling indoors to control respirable dust. Replace the bit if the cutting edges become rounded or if drilling speed and accuracy degrade significantly.
