Drill bit RAWLPLUG SDS MAX 38 mm RT-MAXT-38/690 – SDS‑MAX carbide masonry bit 38mm

The RAWLPLUG SDS MAX 38 mm RT-MAXT-38/690 is an SDS‑MAX shank carbide masonry drill bit designed for use with hammer drills and rotary hammers. With a 38 mm cutting diameter it is intended for making larger holes in concrete, reinforced concrete and masonry where anchors, dowels or pipe passages are required. The bit combines a carbide tip with a flute geometry optimised for fast dust removal and consistent drilling performance in heavy-duty applications.

Advantages

This drill bit features a carbide-tipped cutting head for improved wear resistance and longer life when drilling abrasive materials. The SDS‑MAX shank ensures secure coupling and efficient energy transfer from hammer drill to bit, reducing slippage during intensive work. The flute design facilitates reliable dust evacuation to maintain drilling speed and reduce binding, while the robust body provides stability and straightness when creating large-diameter holes.

Suitable for

• Drilling holes for anchors and dowels in concrete and reinforced concrete
• Creating passages for pipelines and cables through masonry walls
• Installation tasks on construction sites requiring 38 mm boreholes
• Preparation work for mechanical fixings and heavy-duty fixtures

Key specifications

• Cutting diameter: 38 mm
• Shank type: SDS‑MAX compatible
• Tip material: carbide for enhanced durability
• Intended materials: concrete, reinforced concrete, masonry
• Application: hammer drilling/rotary hammer use for through-holes and anchor holes

How to use

Select a compatible SDS‑MAX hammer drill and secure the bit in the chuck according to the tool manufacturer’s instructions. Mark the drilling position and use appropriate personal protective equipment, including eye and hearing protection and a dust mask. Start drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action to do the work. Periodically withdraw the bit to clear dust and check progress. For deep holes, remove debris frequently to maintain drilling efficiency.

Usage recommendations

Use the bit with a hammer drill suitable for SDS‑MAX accessories and match drill speed and applied pressure to the material. For reinforced concrete, use intermittent drilling and clear debris often. When installing anchors or pipes, verify hole depth and cleanliness before fixing. Replace the bit when cutting performance noticeably decreases to ensure accurate, safe holes.
