Drill bit Proline SDS+ 12×450 mm — long masonry/concrete bit for rotary hammers

Proline SDS+ 12×450 mm drill bit designed for industrial and professional use. Intended for drilling in concrete, granite and other natural stones; the special-shaped carbide tip increases service life, improves cutting efficiency and ensures accurate centering while reducing load. The double flute design provides fast dust removal. Suitable for rotary hammers with an SDS+ chuck.

Advantages

The carbide insert with a tailored geometry extends tool life and maintains high drilling performance. The double-spiral flute evacuates dust quickly, reducing binding and improving progress. Compatible SDS+ shank ensures secure mounting in most rotary hammers. The 12×450 mm dimensions offer deep penetration for through and blind holes in masonry and stone.

Suitable for

• Drilling holes in reinforced and non-reinforced concrete
• Drilling in granite and natural stone
• Creating deep anchor and through holes in masonry
• Professional construction and renovation work with rotary hammers

How to use

Install the drill bit into an SDS+ rotary hammer according to the tool manufacturer's instructions until it locks. Use the appropriate hammer drilling mode for concrete and stone. Begin drilling at low pressure to establish the hole center, then apply consistent axial force while letting the tool do the work. Periodically withdraw the bit to clear dust and check progress when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask, hearing protection and gloves). For reinforced concrete, verify reinforcement location before drilling. For prolonged drilling sessions, allow intermittent cooling pauses to prolong bit life and maintain drilling efficiency.
