Drill bit Smart SDS‑Max 55 x 600 mm — through‑type percussive bit

The Smart SDS‑Max 55 x 600 mm through‑type percussive drill bit is designed for heavy rotary‑hammer drilling in concrete and masonry. With a 55 mm diameter and 600 mm length, this through‑type bit provides the reach and cutting diameter needed for making through holes for anchors, dowels, and conduit runs. Fitted with an SDS‑Max shank, it is compatible with SDS‑Max rotary hammers and built for repeated percussive use on construction and renovation sites.

Advantages

The through‑type design enables efficient dust removal from the hole during drilling and maintains consistent percussive impact along the full length of the bit. The SDS‑Max shank ensures secure engagement with compatible rotary hammers and simplifies bit changes under jobsite conditions. The bit’s dimensions — 55 mm diameter and 600 mm length — offer a balance between hole size and depth for standard anchor and fixing installations. Materials and cutting geometry are optimized for durability and stable drilling performance in reinforced concrete and masonry.

Suitable for

• Drilling through holes in concrete and dense masonry for anchors and sleeves
• Installing expansion anchors and dowels in structural and non‑structural applications
• Creating passages for pipes, conduits, or cabling where deep, straight holes are required
• Construction, renovation, and installation work requiring percussive SDS‑Max drilling

Key specifications

• Shank type: SDS‑Max compatible
• Drill diameter: 55 mm
• Total length: 600 mm
• Type: through‑type (flute for dust removal)
• Intended material: concrete and masonry (including reinforced concrete)
• Application: percussive rotary‑hammer drilling

How to use

Mount the bit securely in an SDS‑Max rotary hammer following the tool manufacturer’s instructions and ensure the bit locks into place. Mark the drilling position, start at low speed to create a guide, then apply steady pressure and engage the hammer function for percussive drilling into concrete or masonry. Maintain alignment to keep the hole straight. Withdraw the bit periodically during long drill runs to clear debris and prevent overheating; the through‑type flute assists in removing dust and cuttings as you drill.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) and, if available, a dust extraction system or wet drilling method to reduce airborne silica dust. Select an SDS‑Max rotary hammer with sufficient power and impact energy for a 55 mm diameter hole in concrete. Inspect the bit for wear or damage before use and replace if cutting edges are rounded or the flute is deformed to maintain drilling efficiency and safe operation.
