Product Overview

Our 6mm SDS Plus 4-Flute Drill Bit is a precision-engineered tool designed for the most demanding masonry and concrete applications. Featuring a specialized 4-Cutter Cross-Tip made of premium Tungsten Carbide, this bit is built to penetrate reinforced concrete, solid brick, and natural stone with unmatched stability.

Unlike standard 2-cutter bits, the symmetrical 4-cutter geometry ensures perfectly round holes, which is essential for the load-bearing integrity of chemical and mechanical anchors used in European, Russian, and Middle Eastern construction projects.

Technical Specifications Table (6mm Series)

We provide the 6mm diameter in multiple lengths to accommodate everything from standard wall plugs to deep-hole anchoring through insulation layers.

Engineering Excellence & Key Advantages

Symmetrical 4-Cutter Cross Tip

The high-density YG8C Tungsten Carbide head features a 90° symmetrical cutting edge. This design prevents the bit from jamming or seizing when it encounters light rebar, ensuring a smooth, continuous drilling experience even in reinforced substrates.

Precision Centering Point

The sharpened centering tip allows for immediate, accurate spot-drilling. This prevents "walking" on smooth surfaces like tile or polished stone, guaranteeing hole accuracy from the very first second of operation.

High-Volume 4-Flute Geometry

The specialized 4-Flute (Quad-Flute) design provides twice the surface area for dust evacuation compared to standard bits. This rapid debris removal reduces friction and prevents "dust packing," significantly extending the bit’s operational service life.

Advanced Induction Brazing

Tips are secured using high-frequency automated induction brazing at temperatures exceeding 1,100°C. This ensures the carbide remains seated and structurally sound even during high-heat, continuous-impact drilling in high-PSI concrete.

Hardened 40Cr Alloy Steel Body

The bit body is forged from premium alloy steel, vacuum-tempered to maintain its toughness in sub-zero climates (Russia) and its structural rigidity in high-heat environments (Middle East).

Professional Applications

• Structural Anchoring: Ideal for installing 6mm expansion bolts and professional plastic wall plugs.

• Electrical & HVAC: Precision drilling for conduit clips, wiring brackets, and climate control sensors.

• Renovation: Efficiently handles aged concrete panels, aerated blocks, and hard silicate brickwork.

• Natural Stone: Smooth drilling in granite, slate, and limestone without cracking the material.

Packaging & Global Logistics

• Individual Retail: Transparent PVC hanging tubes with size-specific technical markings.

• Professional Sets: Mixed-size kits (e.g., 5-pc or 7-pc) in high-impact ABS plastic cases.

• OEM & Custom Branding: High-precision Laser Marking available for brand logos and localized technical data directly on the shank.

• Global Shipping: Moisture-proof inner boxes and reinforced outer cartons palletized for long-distance sea and rail freight to Europe and the CIS regions.

FAQ (Frequently Asked Questions)

Q: Why is a 4-flute design better for a 6mm bit?

A: In smaller diameters like 6mm, dust can easily clog the hole. The 4-flute design provides multiple parallel channels to pull dust out instantly, keeping the bit cool and the drilling speed consistent.

Q: Can this 6mm bit be used in reinforced concrete?

A: Yes. The 4-cutter cross-tip is specifically designed to handle the impact of light rebar without snapping, which is the most common failure point for standard 2-cutter bits.

Q: Is the SDS-Plus shank compatible with all major professional drill brands?

A: Absolutely. Our shanks are precision-machined to international ISO and DIN standards, ensuring 100% compatibility with all SDS-Plus rotary hammers.
