Drill Bit AWTools SDS-Plus 12 x 400 mm — QUADRO XTREME BLACK LINE

AWTools SDS-Plus 12 x 400 mm — QUADRO XTREME BLACK LINE is a rotary drill bit designed for use with SDS-Plus rotary hammers to drill into concrete, masonry and natural stone. With a 12 mm diameter and 400 mm overall length, this bit is intended for medium-depth holes and supports both rotary drilling and hammering modes. The QUADRO XTREME BLACK LINE finish indicates a dark protective coating that reduces friction and surface wear during repeated use.

Advantages

The SDS-Plus shank ensures secure coupling with compatible rotary hammers, enabling efficient power transfer during impact drilling. The 12 mm diameter provides a balance between drilling speed and hole strength for common anchor and dowel sizes. A durable tip geometry and reinforced flute design improve debris removal and maintain cutting performance in concrete and masonry. The 400 mm length allows reaching medium-depth fixing points without the need for extension rods.

Suitable for

• Drilling anchor and dowel holes in concrete and blockwork
• Installing electrical conduits and plumbing sleeves through masonry
• Preparing holes for medium-depth fixings in stone and brick
• General renovation and construction tasks using SDS-Plus rotary hammers

Key specifications

• Shank type: SDS-Plus compatible
• Diameter: 12 mm
• Overall length: 400 mm
• Intended materials: concrete, masonry, natural stone
• Recommended drilling modes: rotary hammer/hammer drilling
• Surface finish: dark protective coating

How to use

Secure the bit in the SDS-Plus chuck of a compatible rotary hammer according to the tool manufacturer’s instructions. Mark the drilling point and start drilling at low speed to establish a guide. Engage hammer drilling mode and apply steady, moderate pressure to allow the bit to break material and evacuate dust through the flute. Periodically withdraw the bit to clear debris and avoid overheating when drilling deep holes. Use appropriate personal protective equipment, including eye and hearing protection, and follow safe handling procedures for power tools.

Usage recommendations

For best results, match the drilling mode and bit diameter to the material and anchor system being used. In reinforced concrete, use controlled pressure and intermittent withdrawal to prolong bit life. Replace the bit when tip wear noticeably reduces performance or accuracy.
