Drill Bit AWTools SDS-Plus 12 x 310 mm QUADRO XTREME BLACK LINE

AWTools QUADRO XTREME BLACK LINE SDS-Plus 12 x 310 mm is a masonry drill bit designed for use with SDS-Plus rotary hammers. With a 12 mm diameter and a total length of 310 mm, this bit provides extended reach for drilling anchor holes, through-holes and other installation tasks in concrete and masonry. The QUADRO XTREME BLACK LINE geometry and hard-wearing finish are intended to improve drilling stability and maintain cutting performance during repetitive use.

Advantages

The SDS-Plus shank ensures secure engagement with compatible rotary hammers for efficient energy transfer and reduced slippage. The 310 mm length offers longer reach compared to standard bits, enabling work in deeper applications without extensions. The QUADRO cutter profile and durable black surface treatment are designed to enhance chip removal and resist wear in abrasive materials, supporting consistent hole quality and extended service life.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating through-holes for pipes and conduits in masonry
• Installation work requiring extended reach with SDS-Plus rotary hammers
• General construction and renovation tasks involving brick, block and stone

Key specifications

• Shank type: SDS-Plus compatible
• Diameter: 12 mm
• Total length: 310 mm
• Tip/geometry: QUADRO cutting profile for improved chip evacuation
• Surface finish: black treated coating for wear resistance
• Intended material: concrete, brick, block, stone and masonry

How to use

Install the drill bit into an SDS-Plus rotary hammer according to the tool manufacturer's instructions, ensuring the bit locks securely in the chuck. Use the hammer drilling mode for concrete and masonry, applying steady pressure while allowing the tool to do the work; avoid excessive force that can shorten bit life. Periodically withdraw the bit to clear dust and debris from the hole for improved drilling efficiency and to reduce overheating.

Usage recommendations

For best results, select an SDS-Plus rotary hammer with an appropriate power rating for 12 mm masonry drilling and use the bit at recommended drill speeds for hammer action. Wear suitable personal protective equipment including eye, hand and hearing protection. If drilling reinforced concrete, reduce feed pressure when encountering rebar and use a suitable rebar-cutting technique or specialized bit when required.
