Drill Bit SDS-Plus DeWalt DT9553 12 x 200/150 mm

DeWalt SDS-Plus DT9553 is a 12 mm diameter rotary hammer drill bit with an overall length of 200 mm and an effective working length of 150 mm. Designed for SDS-Plus chucks, this bit is intended for drilling precise holes in masonry, concrete and natural stone during construction and renovation projects. The carbide tip and flute geometry provide reliable chip removal and consistent performance when used with compatible SDS-Plus rotary hammers.

Advantages

The DeWalt DT9553 combines a 12 mm solid shank with a durable carbide cutting head to maintain cutting performance through repeated use. Its length ratio of 200 mm overall to 150 mm working depth balances reach and rigidity, allowing accurate holes without excessive flex. Optimised flute design promotes efficient dust and debris extraction, which helps preserve drill speed and prolong tool life when used correctly.

Suitable for

• Drilling anchor and fixing holes in concrete
• Making through-holes in masonry and brickwork
• Preparing mounting points in stone and similar substrates
• General renovation and construction drilling tasks

Key specifications

• Diameter: 12 mm
• Overall length: 200 mm
• Working length (effective drilling depth): 150 mm
• Shank type: SDS-Plus
• Tip material: carbide cutting head
• Intended materials: masonry, concrete, natural stone

How to use

Secure the drill bit into an SDS-Plus rotary hammer according to the tool manufacturer’s instructions until it locks. Mark the drilling point, starting with a low rotation speed to position the bit, then apply steady pressure and use the hammer mode appropriate for concrete or masonry. Periodically withdraw the bit to clear dust from the hole and avoid overheating. For through-holes, maintain a consistent feed and keep the tool aligned with the drilling axis.

Usage recommendations

Use personal protective equipment such as safety glasses, ear protection and dust mask when drilling. Match the DT9553 bit with rotary hammers sized for SDS-Plus shanks and operate within recommended speed and hammering parameters for the substrate to ensure optimal life and accurate holes.
