Drill Bit SDS‑MAX AWTools 25 x 800 x 940 mm (AW43846) for rotary hammers

AWTools SDS‑MAX drill bit with a nominal diameter of 25 mm and a working length of 800 mm (overall length 940 mm) is designed for use with SDS‑MAX rotary hammers. The bit is intended for drilling deep holes in concrete, reinforced concrete, masonry and natural stone where a long reach is required. The SDS‑MAX shank provides secure connection and efficient impact transfer from compatible rotary hammers, enabling consistent drilling performance for installation and construction tasks.

Advantages

The drill bit combines a long working length with SDS‑MAX shank compatibility to facilitate deep, accurate holes without frequent repositioning. Its design prioritizes stability and efficient energy transfer from the tool to the bit, reducing walking and improving drilling speed in hard substrates. The overall length provides additional reach for installations, making it suitable for anchor, rebar clearance and through‑wall drilling where access is limited.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating passage holes for installations through masonry and stone
• Construction and renovation tasks requiring extended reach
• Preparatory drilling for anchors, dowels and through‑fixings

Key specifications

• Nominal diameter: 25 mm
• Working length: 800 mm
• Overall length: 940 mm
• Shank type: SDS‑MAX compatible
• Intended materials: concrete, reinforced concrete, masonry, natural stone

How to use

Mount the drill bit into an SDS‑MAX compatible rotary hammer according to the tool manufacturer's instructions, ensuring the shank locks securely. Select appropriate speed and hammer settings for concrete or masonry work. Position the bit perpendicular to the surface and apply steady pressure while allowing the hammer action to perform the cutting. Withdraw periodically to clear debris and prevent excessive heat build‑up. For long or deep holes, use suitable supports or guides to maintain alignment.

Usage recommendations

Use appropriate personal protective equipment including eye, ear and respiratory protection when drilling. For reinforced concrete, inspect for rebar and use drilling methods suitable for mixed materials. If drilling through walls or structures, check for hidden services before starting. Follow the rotary hammer manufacturer's guidance for maximum recommended bit length and operating parameters to ensure safe and efficient use.
