NEO tools SDS Max concrete drill bit 28 x 800 mm S4 quatro

The NEO tools SDS Max concrete drill bit 28 x 800 mm S4 quatro is a heavy-duty drilling accessory engineered specifically for demanding construction and renovation tasks. Designed for use with rotary hammers featuring an SDS Max chuck system, this drill bit provides reliable performance when working with extremely hard materials such as concrete, reinforced concrete, masonry, and natural stone. The robust construction and specialized geometry ensure long-lasting durability even under continuous professional workloads.

Advantages

This drill bit features an advanced S4 quatro head geometry that significantly enhances drilling speed and precision while reducing vibration during operation. The multi-cutter design distributes the impact force evenly, preventing the bit from getting stuck when encountering steel reinforcement bars within concrete structures. Additionally, the optimized flute design ensures rapid and efficient dust removal from the hole, which minimizes heat buildup and extends the overall lifespan of the accessory.

Suitable for

• Drilling deep holes in solid concrete and reinforced concrete
• Professional construction and heavy renovation work
• Installation of anchor bolts, conduits, and piping through thick walls
• Masonry and natural stone drilling applications

When it may not be suitable

This drill bit is not designed for standard rotary hammers that use SDS Plus chucks, as it requires an SDS Max machine. Furthermore, it is generally oversized and unnecessarily heavy for light household tasks or drilling into soft materials such as drywall, wood, or sheet metal.

Key specifications

• Bit diameter: 28 mm
• Total length: 800 mm
• Working length: tailored for deep drilling applications
• Chuck type: SDS Max
• Head design: S4 quatro multi-cutter
• Application: Concrete, masonry, and stone

How to use

Insert the drill bit securely into the SDS Max chuck of your rotary hammer until it locks into place. Ensure the tool is set to hammer drill mode before starting. Apply steady, moderate pressure to the drill, allowing the hammer mechanism and the S4 quatro head to do the heavy work. Periodically clear dust from the hole during deep drilling operations to prevent binding and overheating. Allow the bit to cool down naturally after extended periods of heavy use.

What to consider before purchase

• Verify that your rotary hammer is compatible with the SDS Max chuck system
• Check that the 28 mm diameter and 800 mm length match your specific drilling requirements
• Ensure your power tool has sufficient impact energy to drive a large-diameter bit effectively

Usage recommendations: Always wear appropriate personal protective equipment, including safety goggles, ear protection, and a dust mask. Inspect the drill bit for wear and damage before each use to ensure safe and efficient operation.
