Drill bit DeWalt SDS-Plus 14×300/250 mm, model DT9569

SDS-Plus rotary drill bit DeWalt DT9569 with 14 mm diameter and 300/250 mm overall/working length is engineered for hammer drilling in concrete, masonry and natural stone. The bit features an SDS-Plus shank for secure seating in compatible rotary hammers and efficient transmission of percussive energy. It is suitable for drilling anchor holes, through-holes and positioning openings where precise, repeatable performance is required.

Advantages

The carbide tip and optimized flute geometry deliver reliable cutting and dust evacuation when drilling into dense materials, reducing bit wear and maintaining drilling speed. The SDS-Plus shank ensures quick bit changes and stable retention in rotary hammers that accept SDS-Plus accessories. The combination of 14 mm diameter with a 300/250 mm length provides a balance of reach and rigidity for typical anchor and through-hole applications.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating through-holes for bolts and anchors in masonry
• Drilling in natural stone and brick
• Professional construction and renovation tasks
• DIY projects requiring robust hammer drilling

Key specifications

• Shank type: SDS-Plus
• Tip material: Carbide cutting tip
• Diameter: 14 mm
• Total length / working length: 300 mm / 250 mm
• Intended material: Concrete, masonry, natural stone
• Application: Hammer drilling (rotary hammer)

How to use

Insert the SDS-Plus shank into the rotary hammer’s chuck until it locks. Select the hammer-drilling mode on the tool and position the bit at the intended drilling point. Apply steady axial pressure while keeping the drill aligned; allow the tool’s percussion action to perform the cutting. Withdraw the bit periodically to clear dust and debris for improved efficiency and cooler operation. After finishing, unlock and remove the bit following the rotary hammer manufacturer’s instructions.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask when drilling. For reinforced concrete, use slower feed and moderate pressure to avoid overloading the bit; clear debris frequently. Match the rotary hammer to bits with SDS-Plus shank and ensure the tool’s power and hammering rate are suitable for a 14 mm carbide-tipped drill to achieve optimal life and performance.
