SDS Max Hammer Drill Bit Hikoki HK-751003 35 x 380 mm

The SDS Max Hammer Drill Bit Hikoki HK-751003 35 x 380 mm is a long masonry bit designed for use with SDS Max rotary hammers. It is intended for drilling large-diameter holes in concrete, stone and other similar hard materials. The bit's length and diameter make it suitable for through-drilling and for installing anchors or sleeves at depths that standard bits may not reach. Compatibility with SDS Max chucks ensures secure fitting and efficient transfer of hammer energy to the cutting head.

Advantages

This SDS Max masonry bit delivers stable centring and good chip evacuation when used in appropriate rotary hammers, reducing the likelihood of binding during deep drilling. Its robust construction provides resistance to wear during repeated use in abrasive substrates. The long working length allows for drilling to greater depths without changing to extension rods, improving on-site efficiency. Designed for professional use, the bit maintains consistent hole diameter for accurate anchor installation.

Suitable for

• Drilling large-diameter holes in reinforced and non-reinforced concrete
• Creating deep holes for chemical or mechanical anchors
• Installing sleeves, plumbing or electrical conduits through masonry
• Renovation and construction tasks requiring extended-reach drilling

Key specifications

• Shank type: SDS Max compatible
• Diameter: 35 mm
• Total length: 380 mm
• Intended material: concrete, stone and masonry
• Application: rotary hammer drilling with percussion

How to use

Select a rotary hammer with an SDS Max chuck and ensure the tool is suitable for the required bit diameter and drilling depth. Insert the bit into the chuck until it locks, then set the tool to hammer drilling mode. Start drilling at low speed to obtain an accurate starting point, then apply steady pressure and maintain tool alignment with the desired hole axis. Periodically withdraw the bit to clear debris and allow cooling when drilling deep holes. After completion, remove dust and inspect the hole for dimensions before installing anchors or sleeves.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction when possible. Match the rotary hammer power and impact energy to the bit diameter to avoid excessive wear. For drilling in reinforced concrete, use intermittent withdrawal to clear steel-cutting debris and consider a dedicated rebar-cutting bit if frequent contact with reinforcement is expected.
