Tomax SDS Max Drill Bit 4-Cutter 36x570 mm

Tomax SDS Max 4-Cutter Drill Bit 36x570 mm;

Ideal for Heavy-Duty Work;

The Tomax SDS Max 4-Cutter Drill Bit 36x570 mm is a high-performance, professional tool designed for heavy-duty drilling operations. Its SDS Max shank standard makes it suitable for use with high-power rotary hammers, and it is particularly preferred for large-diameter and deep hole drilling projects.

Areas of Use and Application Sectors

The 36 mm diameter and 570 mm total length make this drill bit ideal for challenging and large-scale applications.

Primary Uses:

Reinforced Concrete Structures: Drilling medium-to-large diameter holes in the toughest materials such as concrete, brick, natural stone, marble, and even lightly reinforced concrete.

Deep Hole Drilling: Opening deep holes that require passing through thick walls or floors, thanks to its 570 mm total length.

Sectors Used In:

Heavy Construction and Building Sector: Drilling holes for main anchor points in new construction projects, bridges, tunnels, and large industrial installations.

Plumbing Projects (Large Diameter): Preparing passage holes for large-diameter pipes, ventilation ducts, and thick cable conduits.

Machine and Equipment Installation: Anchor holes for securing large machinery and industrial equipment to floors or concrete platforms.

Renovation and Reinforcement: Drilling deep holes for chemical anchors or epoxy injections in structural reinforcement projects.

Material Properties and Technical Details

The performance of the Tomax 36x570 mm drill bit stems from its superior material technology and special 4-cutter (diamond/carbide) design.

Material Properties

Body Material: Manufactured using high-quality special alloy steel (typically high-performance Chrome-Nickel-Molybdenum or similar tool steel) which provides excellent impact resistance. The reinforced core minimizes the risk of bending and breakage, especially in deep holes.

Cutting Tip (4-Cutter / Carbide Tip): The cutting head of the bit is made from Tungsten Carbide alloy, which offers the highest wear and impact resistance. The 4-Cutter (4 cutting edges) design offers critical advantages over traditional 2-cutter tips:

Faster Drilling: Breaks down material more effectively and increases drilling speed.

Excellent Centering: Maintains bit centering and prevents deviation upon striking rebar (reinforcement steel).

Longer Lifespan: Distributes the load across four cutters, reducing wear on each individual cutter.

Spiral Geometry (Helix): Optimized spiral flutes rapidly evacuate large amounts of dust and debris generated during drilling, preventing clogging and overheating.

User Information and Performance Advantages

The SDS Max series is one of Tomax's most powerful drilling solutions, providing users with superior control and efficiency.

User Advantages

Maximum Power Transfer: The SDS Max shank is larger and stronger than SDS Plus, allowing it to transfer high impact energy fully to the 36 mm diameter. It will not detach from the drill even under high torque.

Ideal for Reinforced Concrete: The 4-cutter design allows for more controlled and faster drilling, even through rebar in reinforced concrete structures.

Fast Debris Removal: Wide and deep spiral flutes ensure quick clearing of dust and debris, which is critical for a bit of this diameter, maintaining drilling efficiency.

Long Service Life: The combination of a high-alloy steel body and a 4-cutter carbide tip provides superior resistance to wear even with intensive and continuous use.

 Safety and Usage Tips

Only use the bit with high-power rotary hammers that have an SDS Max chuck.

When drilling with a bit of this size, it is mandatory to use a two-hand grip and appropriate personal protective equipment (safety glasses, gloves, ear protection).

To prevent overheating and extend the life of the bit, apply an intermittent drilling and dust clearing routine, especially when working in deep holes.
