Drill bit AWTools SDS Max 16 x 800 x 940 mm

The AWTools SDS Max 16 x 800 x 940 mm drill bit is a long-reach rotary hammer bit designed for drilling deep, precise holes in concrete, masonry and other hard construction materials. With a 16 mm diameter and an 800 mm working length, this SDS Max bit fits SDS Max rotary hammers and provides an extended overall length for applications that require access to recessed or hard-to-reach areas. The bit’s geometry and shank type are matched to the impact and rotation forces of SDS Max tools to maintain drilling stability and hole straightness over long depths.

Advantages

This SDS Max drill bit offers an extended working length that enables deep drilling while preserving bit rigidity and stability. The SDS Max shank ensures secure retention in compatible rotary hammers and efficient transfer of impact energy for faster progress in concrete and masonry. The 16 mm diameter provides a balance between hole size and structural integrity of the drilled substrate, making it suitable for anchors, dowels and conduit routes. The overall length gives additional reach for installations where scaffolding or special positioning would otherwise be required.

Suitable for

• Drilling deep anchor and dowel holes in concrete and reinforced concrete
• Creating through-holes and service routes for electrical conduits and piping in masonry walls
• Installation and renovation tasks requiring access to recessed or hard-to-reach drilling points
• Professional construction and trade applications using SDS Max rotary hammers

Key specifications

• Diameter: 16 mm
• Working length: 800 mm
• Overall length: 940 mm
• Shank type: SDS Max compatible
• Intended materials: concrete, masonry and other hard mineral substrates

How to use

Install the bit into the SDS Max chuck of a compatible rotary hammer following the tool manufacturer’s instructions and ensure the lock mechanism engages fully. Select the rotary hammer’s percussion mode suitable for drilling in concrete and set an appropriate speed and impact setting according to material hardness. Position the bit at the drilling point, apply steady axial pressure, and let the tool’s impact action advance the bit; avoid excessive side load to maintain hole straightness. Periodically withdraw the bit to clear dust and debris and reduce heat buildup, and use water flushing only if compatible with the tool and site safety requirements.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or extractor when drilling concrete and masonry. Match drill diameter to anchor or sleeve specifications, and verify that rebar or embedded services are avoided before drilling. For extended drilling depths, monitor bit wear and replace the bit when cutting performance decreases to maintain hole accuracy and reduce stress on the rotary hammer.
