Masonry drill bit DeWalt DT8926-QZ — 8 mm, for rotary hammer, 1 pc

DeWalt DT8926-QZ masonry drill bit, 8 mm diameter, designed for use with rotary hammers and hammer drills for reliable drilling in concrete, brick and other masonry. This single-piece carbide-tipped bit features an SDS Plus shank and a four-flute helix for efficient debris removal and stable drilling. With a 310 mm overall length, it is suitable for making plug and anchor holes where an 8 mm diameter opening is required.

Advantages

The four cutting faces on the solid carbide tip reduce the risk of jamming on reinforced sections and improve cutting efficiency. A brazed carbide tip bonded to a hardened steel body provides durability under repeated impact and rotary load. The 4-flute helix accelerates dust and debris evacuation from the hole, helping maintain drilling speed and preventing clogging. The SDS Plus shank enables fast, secure tool engagement and reliable power transfer from rotary hammers.

Suitable for

• Drilling plug and anchor holes in concrete and structural masonry
• Creating fixing points for installations in brick and block walls
• Preparing holes for through-fixing and dowels in stone and similar materials

Key specifications

• Drill bit diameter: 8 mm
• Overall length: 310 mm
• Shank type: SDS Plus
• Tip material: solid carbide with brazed bond
• Flute design: 4-flute helix for improved debris removal
• Intended materials: concrete, masonry, stone
• Pack quantity: 1 piece

How to use

Fit the SDS Plus shank securely into the rotary hammer or hammer drill according to the tool manufacturer’s instructions. Select hammer mode when drilling into concrete or dense masonry; for lighter masonry, use rotary or combined mode as appropriate. Position the bit perpendicular to the work surface, apply steady pressure and allow the tool to do the cutting—avoid forcing the bit. Periodically withdraw the bit to clear debris and prevent overheating when drilling deep holes.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and a dust mask. For reinforced concrete, drill slowly and check for rebar; the four cutting faces improve resistance to jamming but reduced feed force and steady operation are advised. Use appropriate anchors and plugs sized for an 8 mm hole, and follow anchor manufacturer guidelines for hole depth and cleaning.
