Drill bit DeWalt DT9517 SDS‑Plus 6 x 260/200 mm

DeWalt DT9517 SDS‑Plus 6 x 260/200 mm is a carbide‑tipped masonry drill bit designed for use with SDS‑Plus rotary hammers. With a 6 mm cutting diameter and an overall length of 260 mm (working length 200 mm), this bit is built to make clean, accurate holes in concrete, brick and natural stone. The SDS‑Plus shank provides secure bit retention and fast bit changes in compatible rotary hammer drills.

Advantages

The carbide tip ensures high wear resistance and prolonged cutting performance when drilling into abrasive masonry materials. The optimized flute geometry evacuates dust efficiently to maintain drilling speed and reduce heat build‑up. The SDS‑Plus shank offers reliable engagement with the chuck for consistent impact transfer and minimizes slippage during heavy use. Designed for repeatable 6 mm holes, it supports accurate positioning of anchors and dowels.

Suitable for

• Drilling 6 mm holes in concrete for anchors and fastenings
• Creating fixing points in brick and blockwork
• Installing dowels and through‑fixings in stone and masonry
• Professional construction and renovation tasks requiring SDS‑Plus rotary hammers

Key specifications

• Cutting diameter: 6 mm
• Overall length: 260 mm
• Working/usable length: 200 mm
• Tip material: carbide
• Shank type: SDS‑Plus
• Intended materials: concrete, brick, natural stone

How to use

Select an SDS‑Plus rotary hammer compatible with a 6 mm masonry bit and secure the DeWalt DT9517 in the tool’s chuck until it locks. Mark the drilling position and use appropriate personal protective equipment, including eye and hearing protection and a dust mask. Start drilling at low speed to establish the position, then apply steady pressure while allowing the hammer action to do the work. Periodically withdraw the bit to clear dust and check hole depth. For through‑holes, support workpieces as needed to prevent chipping on exit.

Usage recommendations

Use the bit primarily in hammer drilling mode on masonry and concrete. For improved bit life and cleaner holes, remove debris frequently and avoid excessive lateral force. Replace the bit when the carbide tip shows visible wear or if drilling efficiency decreases.
