The Bosch PRO SDS Plus-5X 14 x 550 mm drill bit is designed for rotary hammers with SDS Plus chucks to create deep, precise holes in concrete and masonry. Its PRO SDS Plus-5X geometry optimises chip removal and stabilises the bit during drilling, allowing steady progress when working with reinforced concrete, stone or brick. The 14 mm diameter and 550 mm overall length provide access to greater depths without the need for extensions while maintaining alignment and drilling accuracy.

Advantages

The drill bit combines a robust carbide tip with a reinforced flute profile to improve wear resistance and drilling stability. The SDS Plus shank ensures secure seating in compatible rotary hammers, reducing slippage and enabling quick bit changes. The flute design is tuned for efficient debris evacuation, which helps reduce clogging and improves penetration speed in dense materials. Overall, the design balances durability, accuracy and dust management for demanding drilling tasks.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating through-holes and blind holes in masonry and brickwork
• Installing mechanical or chemical anchors and fixings
• Professional construction and renovation tasks requiring consistent hole depth
• DIY projects that need precise, long-reach drilling in hard substrates

Key specifications

• Diameter: 14 mm
• Total length: 550 mm
• Shank type: SDS Plus
• Material tip: carbide
• Intended material: concrete, reinforced concrete, masonry, brick
• Design feature: flute profile optimised for dust/debris removal

How to use

Install the drill bit into a compatible rotary hammer with an SDS Plus chuck until it locks securely. Select a hammer or rotary hammer mode as recommended for concrete drilling, set the appropriate drilling speed or impact energy according to the tool manufacturer and begin drilling with steady pressure, allowing the bit to advance without forcing. Periodically withdraw the bit to clear accumulated dust and debris if drilling deep holes; this helps maintain penetration rate and prevents overheating. Wear suitable protective equipment such as eye protection, hearing protection and a dust mask when drilling.

Recommendations

For best results when drilling deep holes in reinforced concrete, use the drill bit with a rotary hammer capable of SDS Plus bits and match the drill speed/impact setting to the material hardness. Regularly clear the hole of debris and replace the bit when the carbide tip shows visible wear to maintain accuracy and reduce effort.
