Drill bit for rotary hammer DRAUMET 628409000, 400 mm, for concrete/masonry/stone, 1 pc

Drill bit for rotary hammer DRAUMET 628409000, length 400 mm, designed for drilling into concrete, masonry and natural stone. This single-piece drill bit is intended for use with SDS Max rotary hammers and is supplied as one unit suitable for long-reach holes and replacement applications in construction and renovation projects.

Advantages

The drill bit is manufactured from hardened materials to provide robust performance and improved tool life. Its cutting geometry is optimized for effective material removal in hard substrates, delivering consistent penetration in concrete, masonry and stone. The 400 mm length allows access to deeper drill points without changing tools frequently, and the SDS Max shank ensures secure fitting and compatibility with a wide range of rotary hammers.

Suitable for

• Drilling through reinforced and non-reinforced concrete for anchor and through holes
• Creating long-reach holes in masonry and natural stone during renovation work
• Replacement or spare bit for heavy-duty drilling tasks on construction sites

Key specifications

• Length: 400 mm
• Intended materials: Concrete, masonry, stone
• Shank type: SDS Max
• Construction: Hardened single-piece design for heavy-duty drilling
• Packaging quantity: 1 piece

How to use

Install the drill bit into an SDS Max compatible rotary hammer following the tool manufacturer's instructions until it locks securely. Select an appropriate drill mode (rotary or rotary-percussion) depending on the material; use percussion mode for concrete, masonry and stone. Start drilling at low speed to establish the datum point, then apply steady forward pressure without forcing the bit. Withdraw periodically to clear debris and allow the bit to cool when making long or deep holes. After use, remove the bit, clean the flute and shank, and store it dry to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control measures. Match drill speed and impact settings to the material and consider pre-drilling pilot holes or using cooling intervals for extended drilling sequences. Replace the bit if signs of excessive wear or chipping appear to maintain drilling efficiency and safety.
