Drill bit AWTools SDS-Plus 12 x 210 mm QUADRO XTREME BLACK LINE

AWTools SDS-Plus 12 x 210 mm QUADRO XTREME BLACK LINE is a percussion drill bit engineered for use with SDS-Plus rotary hammers. With a 12 mm working diameter and 210 mm overall length, this masonry bit is intended for drilling into concrete, brick and natural stone. The SDS-Plus shank ensures secure, quick engagement with compatible hammer chucks and efficient transfer of impact energy for routine construction and installation tasks.

Advantages

The QUADRO XTREME BLACK LINE design combines a wear-resistant black surface treatment with a geometry optimized for fast dust evacuation and stable drilling. The SDS-Plus shank provides reliable locking and reduced wobble under heavy percussion loads. This drill bit delivers consistent hole quality and extended service life when used with appropriate rotary hammers and correct drilling technique.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Creating openings in brick and block walls
• Work on natural stone and masonry during renovations
• Installation tasks requiring repeated percussion drilling with SDS-Plus hammers

Key specifications

• Diameter: 12 mm
• Overall length: 210 mm
• Shank type: SDS-Plus compatible
• Intended material: concrete, masonry, natural stone
• Coating: black wear-resistant surface treatment
• Design features: optimized flute geometry for dust removal and stable percussion performance

How to use

Select a compatible SDS-Plus rotary hammer and secure the QUADRO XTREME BLACK LINE bit in the chuck until it locks. Mark the drilling point and start at low speed to position the bit, then apply steady pressure with the hammer set to percussion mode. Allow the machine to deliver impact energy rather than forcing the bit; withdraw periodically to clear debris and keep the hole straight. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling.

Usage recommendations

For best results, match the drill bit diameter to anchor or fastener specifications and use a hammer with suitable power for 12 mm masonry drilling. Avoid excessive lateral force and replace the bit if wear affects drilling accuracy or increases break-through resistance.
