What is an SDS Max Core Bit?

Definition and Function

An SDS Max Core Bit is designed specifically for use with hammer drills, ideal for creating large diameter holes in hard materials like concrete, brick, and stone. SDS Max stands for “Slotted Drive System Max,” referring to the bit’s shank and its compatibility with SDS Max hammer drills.

  • Large Diameter Drilling: Ideal for large, clean holes.
  • Robust Shank Design: Provides superior grip and torque.
  • Heavy-Duty Compatibility: Perfect for powerful hammer drills.

How Does an SDS Max Core Bit Work?

SDS Max Core Bits utilize a combination of rotational and hammering actions. The hammer drill delivers rapid, high-force impacts while the bit rotates, efficiently breaking through tough materials.

Advantages of Using SDS Max Core Bits

  1. Efficiency in Tough Materials
  • Designed for drilling through hard materials like concrete and reinforced steel.

2. Durability and Longevity

  • Built from high-quality materials to withstand extreme forces and last longer.

3.Precision and Clean Cuts

  • Enables precise and clean cuts, reducing the need for further finishing.

4. Versatility and Compatibility

  • Compatible with a wide range of SDS Max hammer drills.
