Fischer SDS Max IV 16/400/540 Drill Bit

The Fischer SDS Max IV 16/400/540 is a high-performance drill bit engineered for professional use with rotary hammers. Designed for creating precise, approval-compliant drill holes, this tool is optimized for demanding applications in concrete, masonry, and natural stone. Its robust construction and advanced head geometry ensure efficient material removal and long-lasting performance in heavy-duty construction and renovation projects.

Advantages

This drill bit features a specialized head with four cutting edges, which significantly reduces the risk of jamming when encountering steel reinforcement within concrete. The integrated centering tip facilitates high-precision drilling, allowing for accurate hole placement from the start. Furthermore, the core-reinforced flute design maximizes energy transfer from the rotary hammer to the tip, resulting in low-vibration operation and increased drilling speed. The PGM-compliant cutting element ensures that every hole meets strict safety and dimensional requirements, providing a perfect fit for anchors and fixings.

Suitable for

• Drilling in reinforced and non-reinforced concrete
• Creating holes in solid masonry and brickwork
• Working with natural stone
• Heavy-duty construction and renovation tasks

When it may not be suitable

This drill bit is specifically designed for SDS Max chuck systems and is not compatible with standard SDS Plus or cylindrical drill chucks. It is also not intended for drilling in wood, metal, or soft materials where a different cutting geometry is required to prevent damage to the workpiece.

Key specifications

• Diameter: 16 mm
• Working length: 400 mm
• Total length: 540 mm
• Shank type: SDS Max
• Cutting head: 4-cutter design

How to use

Insert the drill bit into the SDS Max chuck of your rotary hammer until it locks securely into place. Ensure the tool is set to hammer-drilling mode. Position the centering tip at the desired mark and apply steady, moderate pressure while maintaining a perpendicular angle to the surface. Allow the drill bit to perform the work, and periodically retract the bit from the hole during deep drilling to clear out accumulated dust and debris, which helps prevent overheating and jamming.

What to consider before purchase

• Verify that your power tool is equipped with an SDS Max chuck system.
• Ensure the 16 mm diameter matches the requirements of the anchors or fixings you intend to use.
• Check that the 400 mm working length is sufficient for the thickness of the material you are drilling.

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Regularly inspect the cutting edges for signs of excessive wear to maintain drilling efficiency and hole accuracy.
