Drill bit Bosch SDS-plus-5X 5.5 x 210 mm, 4‑cutters, model 2608833776

Bosch SDS-plus-5X 5.5 x 210 mm drill bit (4-cutters) is a rotary hammer accessory for SDS-plus chucks, designed for drilling accurate through-holes and deeper holes in concrete, masonry and natural stone. With a total length of 210 mm and a working length suitable for most fixture and anchor installations, the bit balances reach and handling for professional and DIY applications. The 4-cutting-edge tip geometry enhances drilling performance and helps remove debris efficiently to produce cleaner holes.

Advantages

The four-cutter tip improves centring, reduces walking at the start of the hole and delivers smoother drilling compared with standard two-cutter designs. Its SDS-plus shank enables fast, secure bit changes and reliable power transfer from compatible rotary hammers. The bit length and diameter provide a combination of reach and precision appropriate for fixing anchors, running conduits and installing fixtures in solid substrates.

Suitable for

• Drilling 5.5 mm holes for anchors and dowels in concrete and masonry
• Through-holes and deeper holes for plumbing and electrical installations
• Professional trade work and home renovation tasks requiring reliable, repeatable holes

Key specifications

• Shank type: SDS-plus compatible shank for rotary hammers
• Diameter: 5.5 mm
• Total length: 210 mm
• Tip: 4-cutting-edge drill geometry for improved debris removal and hole quality
• Suitable materials: concrete, masonry, natural stone

How to use

Insert the SDS-plus shank into the rotary hammer chuck until it locks in place. Select an appropriate hammer drilling mode on the tool and set the speed/impact settings according to the substrate hardness. Start drilling with steady pressure, allowing the bit to do the cutting; avoid excessive lateral forces to maintain tip alignment and extend bit life. Withdraw the bit periodically to clear dust and debris from the hole when drilling deep or long holes.

Usage recommendations

Wear suitable eye protection, hearing protection and a dust mask when drilling. Use a vacuum or compressed air to clear dust from the hole for better anchor adhesion. Replace the bit when you notice reduced drilling performance or significant tip wear to maintain hole accuracy.
