Vasara­pora Bosch Expert Max-8X — 30 mm poranterän halkaisija, 400 mm työpituus

The Bosch Expert Max-8X hammer drill is a purpose-built drilling tool for heavy-duty impact drilling in masonry and concrete. Designed for a 30 mm drill diameter and a 400 mm working length, this drill bit supports deep-hole drilling tasks where extended reach and stable penetration are required. Bosch engineering focuses on impact resistance and dimensional stability to ensure consistent performance in construction and installation work.

Advantages

The drill combines a 30 mm cutting diameter with a 400 mm working length to enable deep anchoring and through-hole applications without frequent repositioning. Its hammer drill geometry and hardened cutting edges provide reliable impact drilling behavior and reduced jamming in dense materials. The shank and flute design ensure effective dust removal from the hole, supporting cleaner drilling and longer tool life under repeated heavy use.

Suitable for

• Deep-hole drilling in concrete and masonry
• Installing heavy anchors and through-fixings
• Construction site and structural installation work
• Drilling where extended reach is required without extensions

Key specifications

• Drill diameter: 30 mm
• Working length: 400 mm
• Type: hammer drill for impact drilling
• Material suitability: concrete, masonry
• Geometry: optimized for impact resistance and dust evacuation

How to use

Select a compatible hammer drill with appropriate SDS or chuck interface for the drill shank, secure the drill firmly in the tool, and set the drill to hammer mode. Mark the drilling point, start at low speed to seat the bit, then increase speed and apply steady axial pressure appropriate for the material. Periodically withdraw the drill to clear dust and allow cooling during long or deep holes. Use appropriate personal protective equipment, including eye protection, hearing protection, and dust control measures.

Recommendations

For best results, use the Bosch Expert Max-8X in hammer drills rated for heavy-duty work; avoid excessive lateral force and allow the bit to clear debris regularly. Match drill diameter and depth to the anchor or through-fixing specification and follow local safety guidance for dust mitigation when drilling concrete.
