Drill bit DeWalt DT6608-QZ, 200 mm length, single piece

The DeWalt DT6608-QZ drill bit is a single-piece, 200 mm long masonry bit designed for rotary and percussion drilling in concrete, masonry, natural and artificial stone, and brick. Built with a carbide tip intended for effective material penetration, this drill bit is suitable for tasks that require deeper or through drilling where a longer tool length is necessary. The single-piece construction offers stable performance in hammer drills and rotary-percussion tools compatible with the bit type.

Advantages

The 200 mm length provides extended reach for deeper holes and through-drilling applications while keeping a compact, single-piece design for reliable centring and reduced wobble. The carbide tip increases durability and wear resistance when working with abrasive masonry materials. The bit is suitable for rotary and percussion modes, enabling flexible use with a range of hammer and SDS-style drills (verify compatibility with your tool). Overall, the design focuses on consistent hole quality and prolonged cutting life in masonry tasks.

Suitable for

• Drilling holes in concrete for anchors and through-fixes
• Creating openings in brick and blockwork for pipework or conduits
• Drilling into natural and artificial stone where longer reach is required
• Renovation and construction tasks requiring deeper or through-hole drilling in masonry

Key specifications

• Length: 200 mm
• Tip material: carbide
• Design: single-piece masonry drill bit
• Drilling modes: rotary and percussion
• Typical applications: concrete, masonry, natural and artificial stone, brick

How to use

Secure the bit in a compatible hammer or rotary-percussion drill according to the tool manufacturer's instructions. Select rotary-percussion mode when drilling masonry and apply steady pressure without excessive force; allow the carbide tip to cut and the drill to do the work. For through-holes, periodically withdraw the bit to remove dust and debris and keep the hole clear. Ensure correct drill speed and feed for the material being drilled and use appropriate personal protective equipment such as safety glasses, dust mask, and hearing protection.

Usage recommendations

Prior to use, confirm shank compatibility with your drill chuck or tool holder. When drilling reinforced concrete, proceed with care and reduce feed pressure if you encounter rebar; use an appropriate rebar-cutting technique or specialist bit. For clean holes and extended bit life, clear dust frequently and avoid overheating by allowing cooling pauses during prolonged drilling.
