## Long description

DeWalt DT6688-QZ 12 mm concrete drill bit with a cylindrical shank is designed for drilling precise holes in concrete and masonry. The 12 mm cutting diameter makes it suitable for standard anchors, dowels and through-holes, while the straight shank fits hammer and rotary drills with a chuck that accepts a cylindrical shank. The bit construction is optimized to withstand percussion drilling in hard substrates and to deliver consistent hole size and straightness for professional and DIY tasks.
Advantages
The DeWalt 12 mm concrete drill bit offers wear-resistant cutting geometry and a durable body that maintains performance under repeated hammering. Its cylindrical shank ensures a secure fit in standard chucks and straightforward replacement. The cutting tip is shaped to penetrate concrete efficiently and reduce wandering at the start of the hole, helping to achieve accurate results with minimal rework.
Suitable for
Drilling holes for wall anchors and dowels in concrete
Creating through-holes in masonry for pipes and conduits
Installing fixings for structural or non-structural elements
Professional construction and renovation work requiring consistent 12 mm bores
DIY projects that involve drilling into brick, block and reinforced concrete (with appropriate drill)
Key specifications
Cutting diameter: 12 mm
Shank type: cylindrical (straight) shank
Intended material: concrete and masonry
Compatibility: hammer drills and rotary drills that accept a straight shank
Typical applications: anchor and dowel hole drilling, through-holes
How to use
Mark the drilling point and secure the work area. Fit the 12 mm cylindrical shank drill bit into a compatible hammer or rotary drill chuck, ensuring it is clamped firmly. Begin drilling at low speed to establish the pilot engagement, then increase to an appropriate hammering speed for concrete while applying steady axial pressure. Periodically withdraw the bit to clear dust and reduce heat build-up. For reinforced concrete, use controlled pressure to avoid excessive wear on the cutting edges.
Usage recommendations
Use eye and hearing protection and a dust mask when drilling. Select a drill with sufficient impact energy for concrete; avoid excessive lateral force on the bit. For deep holes, withdraw the bit frequently to clear debris. Replace the bit when cutting performance or hole accuracy declines.
