Masonry drill bit DeWalt DT8929 for rotary hammer — 10 mm, 1 pc

DeWalt DT8929 masonry drill bit is a single 10 mm diameter bit designed for use with SDS‑plus rotary hammers. Engineered to drill into masonry, concrete and natural stone, this bit provides a straightforward solution for contractors and DIY users who require a compact, durable tool for holemaking during construction, renovation and installation tasks. The bit's geometry and carbide tip are optimized for impact drilling with rotary hammers, delivering consistent drilling performance for small to medium‑scale fastening and anchoring jobs.

Advantages

The DeWalt DT8929 offers durable carbide tip construction and a flute profile that evacuates dust efficiently during drilling. Compatibility with standard SDS‑plus chucks ensures secure mounting and reliable power transfer from the rotary hammer. With a 10 mm diameter, the bit balances penetration speed and hole accuracy for anchor bolts, dowels and service penetrations. The single‑piece supply makes it easy to carry and replace on site.

Suitable for

• Drilling holes for anchors and plugs in concrete and masonry
• Installing electrical boxes, conduits and plumbing fixtures
• Light to medium construction and renovation tasks requiring impact drilling
• Work on natural stone and brick where a 10 mm hole is required

Key specifications

• Shank type: SDS‑plus compatible
• Diameter: 10 mm
• Intended materials: concrete, masonry, brick, natural stone
• Tip material: carbide tip for impact drilling
• Quantity: single piece

How to use

Fit the 10 mm DeWalt masonry bit into an SDS‑plus rotary hammer chuck and ensure it locks securely before starting. Select the hammer drilling mode on the tool and apply steady, moderate pressure; allow the tool's impact action to do the cutting rather than forcing the bit. Periodically withdraw the bit to clear dust from the hole and improve drilling efficiency. For deeper holes or prolonged drilling, use short pauses to avoid overheating the bit.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Match drill speed and hammer impact settings to the base material; for reinforced concrete, progress carefully and switch to a fresh bit when tip wear reduces drilling efficiency. Store the bit dry and protected to maintain the carbide tip condition.
