SDS Max drill bit Proline 25 x 520 mm for masonry and concrete

SDS Max drill bit Proline 25 x 520 mm designed for industrial and professional use. Intended for drilling in concrete, reinforced concrete and masonry. The 520 mm length and 25 mm diameter provide deep, wide holes while the SDS Max shank ensures secure retention in compatible hammer drills and rotary hammers.

Advantages

Double spiral flute design enables efficient dust extraction and faster debris removal during drilling. A four-flute carbide insert with optimized geometry at the drill tip delivers stable percussion transfer and improved cutting performance. Built for continuous use on construction and renovation sites, the bit provides reliable bit retention and consistent drilling results in hard materials like concrete and granite.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Masonry drilling (brick, block, stone)
• Heavy-duty construction and renovation tasks
• Use with SDS Max hammer drills and rotary hammers

How to use

Fit the SDS Max shank securely into a compatible hammer drill or rotary hammer. Mark the drilling position and start drilling at low speed to create a pilot groove, then increase to appropriate impact drilling speed according to the drill manufacturer's recommendations. Apply steady axial pressure without forcing the bit; allow the hammer action and double spiral to clear debris. Withdraw periodically to remove dust and prevent overheating.

Usage recommendations

For best results use with properly maintained SDS Max hammer drills and appropriate drilling parameters for the material. Wear suitable personal protective equipment (safety glasses, hearing protection, dust mask). Replace the bit if the carbide tip is worn or damaged.
