Drill bit AWTools SDS Plus 12×260 mm Quadro Xtreme Black Line

The AWTools SDS Plus 12×260 mm Quadro Xtreme Black Line drill bit is designed for rotary and hammer drilling in concrete, masonry and natural stone with SDS Plus chuck systems. With a 12 mm diameter and a 260 mm overall length, this bit provides a balance of rigidity and reach for deeper anchoring, through-holes and installation work. The Quadro Xtreme geometry and Black Line surface finish are engineered to reduce wear and improve bit life under frequent use on tough substrates.

Advantages

The Quadro Xtreme cutting profile offers efficient material removal and reduced binding during rotary-hammer operation, while the Black Line coating helps protect the flute and shank from corrosion and abrasion. A 12 mm shank size ensures secure engagement with SDS Plus chucks and consistent transfer of percussion energy. The 260 mm length gives sufficient working reach for common construction tasks without compromising bit stiffness.

Suitable for

• Drilling holes in reinforced and plain concrete
• Fixing and anchor installation in masonry
• Through-holes for pipes and conduits in stone and brickwork
• General renovation and construction drilling tasks

Key specifications

• Overall length: 260 mm
• Shank type: SDS Plus compatible
• Point/geometry: Quadro Xtreme cutting profile
• Surface finish: Black Line protective coating
• Intended use: Rotary and hammer drilling in concrete, masonry and stone

How to use

Fit the bit into an SDS Plus chuck ensuring it locks securely before starting the tool. Select a suitable rotary-hammer mode and use steady axial pressure while allowing the tool to provide the percussion action; avoid excessive side loading. For deeper holes, periodically withdraw the bit to clear dust from the hole and maintain drilling efficiency. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling.

Usage recommendations

For best results in reinforced concrete, start with a pilot hole if necessary and maintain moderate feed pressure. Replace the bit when cutting efficiency noticeably decreases or when the tip/wear pattern becomes damaged to avoid poor hole quality and increased tool stress.
