Drill bit AWTools SDS‑Plus QUADRO XTREME BLACK LINE 6 mm x 310 mm

AWTools SDS‑Plus QUADRO XTREME BLACK LINE drill bit, 6 mm diameter and 310 mm length, is designed for rotary and hammer drilling in masonry and concrete with SDS‑Plus chucks. The extended length provides reach for through‑holes and deeper anchor holes while keeping compatibility with standard SDS‑Plus rotary hammers. Intended for professional tradespeople and DIY users who need a slim, long bit for precise drilling in stone, block, and reinforced concrete where a narrow bore is required.

Advantages

This 6 x 310 mm drill bit combines an SDS‑Plus shank for secure tool engagement with a hardened head geometry optimized for masonry and concrete. The QUADRO XTREME BLACK LINE finish improves surface hardness and reduces wear during repeated hammer action. The long length enables drilling through thicker walls and installations without switching to extensions, and the slim diameter minimizes material removal for accurate anchor and through‑hole placement.

Suitable for

• Drilling anchor holes in concrete, brick, and block
• Through‑holes for wiring or pipes in masonry walls
• Tasks requiring extended reach where a 6 mm bore is sufficient
• Use with SDS‑Plus rotary hammers on construction or renovation sites

When it may not be suitable

This bit is not intended for use in metal, wood, or ceramic tile; using it in those materials will reduce performance and may damage the tip. For very large diameters or extremely hard reinforced concrete where high removal rates are required, a larger or specialized bit (e.g., core bit or carbide‑tipped heavy‑duty bit) would be more appropriate.

Key specifications

• Diameter: 6 mm
• Total length: 310 mm
• Shank type: SDS‑Plus compatible
• Intended material: masonry and concrete
• Finish: Black protective coating (BLACK LINE)

How to use

Attach the bit to an SDS‑Plus rotary hammer according to the tool manufacturer's instructions until it locks securely. Select hammer or rotary‑hammer mode depending on material hardness. Begin drilling at low speed to establish the hole, then apply steady pressure and allow the hammer action to advance the bit; avoid excessive lateral force. Withdraw periodically to clear dust from the hole for efficient cutting and reduced wear. Use appropriate eye, ear and dust protection, and secure loose workpieces before drilling.

What to consider before purchase

• Compatibility with your SDS‑Plus rotary hammer chuck
• Required hole diameter and whether 6 mm meets your anchor or through‑hole needs
• Needed length for the application — 310 mm total length gives extended reach
• Material to be drilled: designed for masonry and concrete, not for metal or wood

Usage recommendations

For best results in concrete and brick, use a rotary hammer in hammer‑drilling mode, start holes at low speed to ensure accuracy, and clear debris regularly. Replace the bit when cutting efficiency drops or the head shows visible wear to maintain clean holes and safe operation.
