Drill bit AWTools AW43775 — model AW43775, weight 2.4 kg

AWTools AW43775 is a professional-grade drill bit designed for heavy-duty drilling in masonry and stone materials. Made of high-quality alloy steel with a tungsten carbide tip, this model features a wide flute and two cutting edges for effective material removal. The 130° self-centering point facilitates accurate starts without a pilot hole, while the double spiral promotes efficient debris evacuation and reduced vibration. A grooved SDS‑MAX shank secures the bit in compatible hammer drills and rotary hammers and helps prevent accidental ejection. The AW43775 is intended for use in workshops, construction sites, and maintenance tasks that require a robust drill bit for masonry, concrete, granite, natural stone, brick and ceramic tiles.

Advantages

The AWTools AW43775 combines a tungsten carbide tip and alloy steel body to balance wear resistance and toughness. Its 130° self‑centering point improves positional accuracy and reduces the need for pilot drilling. The double spiral geometry enhances dust and chip extraction, lowering the risk of overheating and reducing vibrations transmitted to the tool. The grooved SDS‑MAX shank provides reliable retention in rotary hammers and hammer drills, enabling continuous work under heavy loads.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Work on natural stone, granite and masonry
• Installing anchors, dowels and fixings in brick and blockwork
• Tile work requiring through-holes in ceramic and porcelain
• Use with SDS‑MAX hammer drills and rotary hammers on construction sites and in workshops

How to use

Install the AWTools AW43775 into an SDS‑MAX compatible hammer drill or rotary hammer, ensuring the shank seats fully and the retention grooves engage. Select appropriate drilling mode (hammer + rotation for masonry/concrete, rotation-only where applicable). Position the self‑centering point on the marked spot and apply steady axial pressure; avoid excessive side load. Use moderate feed speed and allow the double spiral flutes to evacuate chips; periodically withdraw the bit to clear debris when drilling deep holes. Observe the drill and bit temperature; let the bit cool if it becomes hot to maintain carbide tip life.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, hearing protection and gloves) and follow the tool manufacturer’s guidelines. For reinforced concrete, use progressive drilling with controlled pressure and periodic withdrawal to clear rebar shavings. When drilling ceramic tiles, start at low speed and use the self‑centering point to avoid cracking. Inspect the carbide tip regularly and replace the bit if excessive wear or chipping is present to maintain drilling performance and safety.
