SDS‑MAX Drill Bit AWTools 35 x 800 x 940 mm

The SDS‑MAX Drill Bit AWTools 35 x 800 x 940 mm is a purpose-built rotary hammer accessory for drilling deep, precise holes in concrete, masonry and other hard substrates. With a 35 mm diameter and an 800 mm working length, this SDS‑MAX bit provides extended reach for through-holes and deep anchoring without the need for extensions. The bit is compatible with SDS‑MAX chucks and is designed to withstand impact drilling forces typical of professional construction and demolition tasks.

Advantages

The solid carbide tip and reinforced flute geometry offer improved drilling speed and bit life when penetrating reinforced concrete and dense masonry. A hardened shank ensures reliable retention in SDS‑MAX tool chucks and reduces slippage during high-torque operation. The long working length allows for single-pass drilling of deep holes, minimizing interruptions and increasing on-site efficiency while maintaining stable drilling performance under impact loading.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating through-holes for plumbing and electrical installations
• Heavy-duty demolition and drilling in masonry structures
• Preparation of holes for chemical anchors and rebar dowels

Key specifications

• Drill diameter: 35 mm
• Working length (usable length): 800 mm
• Overall length: 940 mm
• Shank type: SDS‑MAX compatible
• Tip material: solid carbide (hardened cutting tip)
• Flute design: reinforced for debris removal during deep drilling

How to use

Secure the SDS‑MAX bit in a compatible rotary hammer according to the tool manufacturer's instructions, ensuring the shank locks fully in the chuck. Mark the drilling position and start at low speed to establish the pilot point, then apply steady pressure and switch to the hammering function as appropriate for concrete or masonry. Maintain consistent axial pressure and periodically extract the bit to clear dust and debris from the hole when drilling deep. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust masks.

Usage recommendations

For best results, match the rotary hammer's impact energy and rotation speed to the bit diameter and material hardness. When drilling through reinforced concrete, advance steadily and allow the carbide tip to wear in rather than forcing excessive pressure. Use water flushing or industrial vacuum extraction where dust control is required, and inspect the bit regularly for tip wear or flute damage to ensure consistent hole quality.
