Drill Bit AWTools SDS‑Plus 14 x 450 mm QUADRO XTREME BLACK LINE

AWTools QUADRO XTREME BLACK LINE SDS‑Plus drill bit 14 x 450 mm is a long masonry bit designed for SDS‑Plus rotary and hammer drills. Intended for drilling into concrete, brick and natural stone, this 450 mm overall length bit provides extended reach for deep holes and through‑wall applications. The QUADRO cutting geometry at the tip improves centering and chip removal, while the black protective finish reduces wear in demanding jobsite conditions. This bit is offered by AWTools for professional construction and heavy‑duty drilling tasks.

Advantages

The QUADRO XTREME BLACK LINE drill bit combines a hardened, geometry-optimized tip with a long shank suitable for SDS‑Plus chucks, enabling stable performance in rotary and hammer drilling modes. The QUADRO cutting geometry helps maintain accurate drilling direction and efficient dust and debris evacuation. The black protective coating increases surface resistance to abrasion and corrosion, extending usable life under repeated impact loading. Overall, it offers a balance of reach, cutting precision and durability for masonry work.

Suitable for

• Drilling holes in reinforced and non‑reinforced concrete
• Creating openings in brickwork and block walls
• Working with natural stone and masonry substrates
• Long‑reach drilling for through‑wall installations and deep anchor holes

When it may not be suitable

This drill bit is not intended for use in metal, wood, or ceramic tile as a primary application; using it in inappropriate materials will reduce performance and may damage the bit or the workpiece. For SDS‑Max machines or very large diameter anchor drilling, a different shank type and size are recommended. The 14 mm diameter is engineered for medium to large anchor and fixture holes, and may be oversized for small delicate fixtures.

Key specifications

• Tip geometry: QUADRO cutting geometry for improved centering and chip removal
• Shank type: SDS‑Plus for compatible rotary and hammer drills
• Diameter: 14 mm
• Overall length: 450 mm (long‑reach design)
• Primary material: hardened steel with protective black finish
• Intended materials: concrete, brick, natural stone, masonry

How to use

Fit the SDS‑Plus shank securely into the drill chuck and ensure the drill is set to the appropriate mode (hammer or rotary‑hammer) for masonry. Mark the drilling point and start at low speed to establish the center, then increase speed and apply steady, moderate pressure. For deep holes, periodically withdraw the bit to clear dust and debris and avoid overheating. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling.

What to consider before purchase

• Confirm compatibility of your drill with SDS‑Plus shanks
• Verify that 14 mm diameter and 450 mm length suit your anchor, rebar or fixture requirements
• Assess suitability for the substrate type (concrete, brick, stone) you will work with
• Consider spare bits if frequent deep drilling or high‑volume work is expected

Usage recommendations

For best results when using the AWTools QUADRO XTREME BLACK LINE 14 x 450 mm SDS‑Plus drill bit, operate the drill at recommended speeds for masonry, clear chips regularly during long holes, and avoid excessive side pressure. Replace the bit when tip wear degrades centering or cutting efficiency to maintain hole accuracy and reduce stress on the drill motor.
