Pora Bosch SDS‑max‑8X 30 mm betonille, pituus 520 mm

The Bosch SDS‑max‑8X 30mm drill bit for concrete, length 520mm is designed for demanding drilling in reinforced and plain concrete. Its 30 mm diameter and 520 mm overall length allow for deep, accurate holes for anchors, conduits and through‑fixings. Optimized for SDS‑max rotary hammers, the bit combines a robust carbide tip with a shaft geometry that supports efficient dust and debris evacuation and steady drilling progress.

Advantages

This Bosch SDS‑max‑8X drill bit offers consistent drilling performance and long service life thanks to a reinforced carbide cutting head that resists wear when working with abrasive concrete. The 520 mm length provides extended reach for deep anchoring tasks while the 30 mm diameter delivers a precise hole size compatible with common anchors and sleeves. Shaft design ensures reliable engagement with SDS‑max tool chucks and promotes removal of drilling debris to maintain drilling speed and reduce binding.

Suitable for

• Drilling deep holes for mechanical anchors and chemical anchors in reinforced and plain concrete
• Creating passages for electrical conduits and plumbing through concrete walls and floors
• Preparation of mounting points for structural fixings and heavy equipment
• Renovation and construction work requiring reliable, repeatable concrete drilling

Key specifications

• Tip material: carbide cutting head designed for concrete
• Shank type: SDS‑max compatible shank for rotary hammers
• Diameter: 30 mm
• Overall length: 520 mm
• Intended material: reinforced and plain concrete
• Function: percussive drilling with rotary hammer

How to use

Install the drill bit into an SDS‑max rotary hammer according to the tool manufacturer’s instructions, ensuring secure engagement of the shank. Mark the drilling location and, if necessary, start with a pilot position at low speed to avoid skating. Apply steady pressure and allow the hammer action to do the work; avoid excessive force that may blunt the carbide tip. Periodically withdraw the bit to clear accumulated debris and check progress. Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask or extraction when drilling indoors.

Recommendations

For extended bit life and optimal performance, match drilling speed and pressure to the concrete hardness, clear dust frequently, and use a compatible SDS‑max rotary hammer with sufficient impact energy. Store the bit dry and protect the carbide tip from impacts when not in use.
