Drill bit AWTools AWTOOLS WIERTŁO SDS+ 28 mm x 800 mm model AW43597

AWTools SDS+ drill bit model AW43597 with a 28 mm diameter and 800 mm overall length is designed for rotary and hammer drilling in concrete, masonry and comparable hard materials. The SDS+ shank ensures secure coupling with compatible hammer drills and rotary hammers, while the long 800 mm length provides extended reach for deep holes and drilling through thick elements or multiple layers. The bit is intended for professional construction, installation and demolition tasks where reinforced, long-reach drilling is required.

Advantages

The SDS+ design delivers quick, secure insertion and reliable power transfer for hammer drilling. Its 28 mm diameter and reinforced flute geometry support efficient dust removal and stable drilling in dense substrates. The extended 800 mm length allows access to recessed areas and through-drilling where standard-length bits are insufficient. The bit is compatible with widely used SDS+ systems, facilitating tool interchangeability on job sites.

Suitable for

• Drilling deep holes in concrete and reinforced concrete
• Through-holes in masonry walls and partitions
• Installation of long anchors, sleeves and through-bolts
• Construction and renovation tasks requiring extended-reach drilling

Key specifications

• Tip diameter: 28 mm
• Overall length: 800 mm
• Shank type: SDS+
• Suitable materials: concrete, masonry and similar hard substrates
• Intended drilling modes: rotary with hammer / percussion drilling

How to use

Select a hammer drill or rotary hammer compatible with SDS+ shanks and clamp the bit securely into the tool according to the tool manufacturer’s instructions. Mark the drilling position and start at low speed to establish the hole, then apply steady pressure and use hammer function for effective penetration in concrete or masonry. Periodically withdraw the bit to clear dust and debris from the hole and flute to maintain drilling efficiency and reduce wear. For through-drilling, verify the bit length is sufficient and ensure safe access to both sides of the drilled element.

Usage recommendations

Use personal protective equipment including eye and hearing protection and a dust mask when drilling. Match drill speed and hammer settings to substrate hardness and avoid excessive lateral force. For reinforcement or rebar contact, stop drilling and assess the situation; consider appropriate cutting or drilling techniques for metal. After use, clean the flute and store the bit dry to prevent corrosion.
