Drill Bit AWTools SDS Plus 16 x 310 mm Quadro Xtreme Black Line

The AWTools SDS Plus 16 x 310 mm Quadro Xtreme Black Line is a masonry drill bit engineered for SDS Plus rotary hammers. With a 16 mm cutting diameter and 310 mm overall length, this bit is intended for drilling into concrete, brick and natural stone. The Quadro Xtreme tip geometry and flute design support sustained percussion drilling and accelerated dust and chip evacuation, making it suitable for extended runs and deeper holes.

Advantages

This AWTools masonry bit combines a robust shank compatible with SDS Plus chucks and a reinforced cutting head to maintain drilling accuracy under percussive load. The extended 310 mm length allows for deeper penetrations without changing tools, while the flute profile helps clear debris to reduce clogging and improve drilling speed. The Black Line finish provides surface protection against corrosion and wear during storage and intermittent use.

Suitable for

• Drilling 16 mm diameter holes in concrete for anchors and dowels
• Creating through-holes in brick and masonry for services and conduits
• Installation work where SDS Plus rotary hammers are used
• Professional and DIY projects requiring deeper masonry holes up to 310 mm

When it may not be suitable

This drill bit is not designed for use in metal, wood or other soft materials; using it in inappropriate materials will reduce performance and shorten service life. It is also not intended for hammerless or non-SDS chucks—an adapter or incompatible tool may cause poor fit and unsafe operation.

Key specifications

• Cutting diameter: 16 mm
• Overall length: 310 mm
• Shank type: SDS Plus compatible
• Intended material: concrete, brick, natural stone (masonry)
• Tip geometry: Quadro Xtreme design for percussion drilling
• Finish: Black Line surface coating

How to use

Secure the AWTools Quadro Xtreme bit in an SDS Plus rotary hammer according to the tool manufacturer’s instructions. Mark the drilling point and start at low speed to position the tip, then apply steady percussion drilling pressure and increase speed as needed. Periodically withdraw the bit to clear dust and chips from the hole and the flute, especially when drilling deep holes. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask.

What to consider before purchase

• Verify that your rotary hammer accepts SDS Plus shanks
• Confirm 16 mm diameter and 310 mm length meet the hole size and depth requirements
• Check compatibility with the masonry materials you will drill (concrete, brick, stone)
• Plan for appropriate drilling speed, percussion settings and PPE

Usage recommendations

For best results in reinforced concrete, use moderate feed pressure and withdraw the bit regularly to remove debris; in brittle masonry, start with a pilot position at low speed to avoid chipping. Store the bit dry and clean to preserve the Black Line finish and check the cutting edges before extended jobs.
