Fischer 504256 SDS Max Drill Bit 35 mm

The Fischer 504256 SDS Max drill bit is a high-performance tool engineered for professional drilling applications in demanding materials. With a diameter of 35 mm and an overall length of 570 mm, this drill bit is specifically designed for use with rotary hammers featuring an SDS Max chuck system. It is built to provide high precision and durability, making it an essential component for construction and renovation projects that require reliable performance in hard substrates.

Advantages

The drill bit features a robust head with four cutting edges, which significantly reduces the risk of jamming when encountering steel reinforcement within concrete. The inclusion of a centring tip ensures accurate positioning and high-precision drilling from the start. Its core-reinforced flute design maximizes energy transfer from the rotary hammer to the tip, resulting in efficient drilling with reduced vibration. Furthermore, the quadruple spiral design promotes effective dust removal, which enhances drilling speed and extends the overall service life of the tool. The cutting element is PGM-compliant, ensuring that every hole created meets strict safety and dimensional standards for secure anchor installation.

Suitable for

• Drilling in reinforced and non-reinforced concrete
• Working with solid masonry and brickwork
• Applications in natural stone
• Professional construction and renovation tasks

When it may not be suitable

This drill bit is not intended for use with standard drill chucks, as it requires an SDS Max connection. It is also not suitable for drilling into soft materials like wood, metal, or plastic, as the aggressive carbide cutting geometry is specifically optimized for mineral-based construction materials.

Key specifications

• Drill bit diameter: 35 mm
• Overall length: 570 mm
• Working length: 450 mm
• Shank type: SDS Max
• Head design: Quadruple-edged solid carbide
• Flute design: Quadruple spiral

How to use

To use the Fischer SDS Max drill bit, ensure your rotary hammer is set to the hammer-drilling mode. Insert the shank into the SDS Max chuck until it clicks into place. Position the centring tip at the desired drilling location and apply steady, moderate pressure. Allow the tool to perform the work, ensuring that the dust is effectively cleared from the hole by periodically pulling the bit back slightly during deep drilling. Always wear appropriate personal protective equipment, including eye and ear protection, during operation.

What to consider before purchase

• Verify that your power tool is compatible with the SDS Max shank system.
• Ensure the 35 mm diameter meets the requirements of your specific anchors or installation needs.
• Check that the 570 mm total length is sufficient for the depth of the material you intend to drill.

For optimal results and to maintain the longevity of the drill bit, avoid excessive lateral pressure and ensure the tool is kept clean of debris. Regularly inspect the carbide tip for signs of wear to maintain drilling precision.
