Drill bit DeWalt DT9511 for rotary hammer, 5.5 mm diameter, 260 mm length, 1 pc

DeWalt DT9511 is a 5.5 mm diameter, 260 mm long drill bit designed for use with rotary hammers. Manufactured for drilling into concrete and masonry, this single-piece bit fits SDS-style chucks on compatible rotary hammer tools to produce accurate holes for anchors, fasteners and through-holes. The length provides extended reach for medium-depth drilling while the 5.5 mm working diameter is suitable for common anchor sizes and dowels used in construction and renovation tasks.

Advantages

The drill bit offers consistent drilling performance and reliable fit in SDS rotary hammer chucks, reducing wobble and improving hole accuracy. Its hardened working end and flute geometry are engineered to clear dust efficiently and sustain cutting performance in abrasive materials. The 260 mm overall length balances reach and control, allowing more precise handling in confined or overhead locations.

Подходит для

• Сверления отверстий под дюбели и анкеры в бетонe и кирпичной кладке

• Сверления сквозных и неглубоких проходных отверстий в стенах

Key specifications

• Working diameter: 5.5 mm
• Overall length: 260 mm
• Shank type: compatible with SDS rotary hammer chucks
• Material suitability: concrete and masonry
• Design: single-piece construction with flute to evacuate debris

How to use

Insert the drill bit fully into the rotary hammer chuck and secure according to the tool manufacturer’s instructions. Select the hammer-drill mode appropriate for concrete or masonry and start drilling at low speed to establish the hole position, then increase speed and apply steady, even pressure. Withdraw the bit periodically to clear dust and prevent clogging; for deeper holes use a blow-out or vacuum to remove debris. Match the bit diameter to the anchor or fastener specified by the manufacturer for proper fit.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Confirm compatibility with your rotary hammer’s chuck type before use and avoid excessive lateral force to preserve bit life and hole accuracy.

DeWalt DT9511 is intended for professional and DIY applications where a 5.5 mm hole in concrete or masonry is required and where a rotary hammer is the recommended tool for efficient drilling.
