Hitachi 754348 drill bit 1 pc(s)

HITACHI SDS-Max 40 x 1320 mm rotary hammer drill bit is a long, carbide-tipped bit engineered for drilling large-diameter holes in concrete, masonry and natural stone. Designed to fit SDS‑Max rotary hammers, this drill bit provides the reach required for deep-bore applications and installations where standard-length bits are insufficient. The robust carbide tip and reinforced shank are intended to withstand the impact and torsion typical of heavy-duty construction and renovation tasks.

Advantages

The carbide-tipped cutting edge maintains drilling performance and wear resistance when working in abrasive materials. Its SDS-Max shank ensures secure and reliable engagement with compatible rotary hammers, reducing play and improving energy transfer. The extended 1320 mm length enables deep penetrations without the need for extension pieces, while the 40 mm diameter provides the clearance necessary for cable ducts, anchor sockets and through-holes. The overall design balances durability and dimensional stability under repeated impact loads.

Suitable for

• Drilling large-diameter, deep holes in reinforced and non-reinforced concrete
• Create openings for pipes, conduits and cable passages in masonry
• Installation of anchors, sleeves and sleeves for mechanical and electrical systems
• Renovation and structural work requiring extended-reach drilling

Key specifications

• Shank type: SDS‑Max compatible
• Diameter: 40 mm
• Total length: 1320 mm
• Tip material: carbide
• Primary application: concrete, masonry, natural stone

How to use

Install the SDS‑Max shank securely into a compatible rotary hammer and verify correct locking before operation. Mark the drilling position and start at low speed to establish the hole; then apply steady pressure and permitted impact action to progress to full depth. Periodically withdraw the bit to clear debris and reduce friction; for long deep holes, use intermittent drilling to allow cooling and dust removal. Follow the rotary hammer manufacturer's guidelines for maximum RPM and impact settings for a 40 mm carbide-tipped bit.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask and gloves). For best life and performance, avoid excessive lateral force and ensure the tool is within recommended power and impact ranges for SDS‑Max 40 mm bits. When drilling reinforced concrete, inspect for rebar and proceed with care to prevent tip damage.
