40Cr Sandblasted SDS Drill Bit 12mm R Flute Sds Hammer Drill
Professional SDS Max Drill Bit: The Industrial Power-Drive Series
1. Product Concept: "The Rebar-Eater"
Designed for the most demanding 10-joule+ rotary hammers, our Professional SDS Max Series is the definitive solution for large-scale infrastructure. While standard bits fail under the intense thermal stress of reinforced concrete, our Power-Drive technology ensures consistent penetration through the densest substrates.
Whether you are anchoring structural steel in Europe, drilling through frozen masonry in Russia, or navigating high-density basalt in the Middle East, these bits are engineered for zero-compromise performance.
2. Technical Specifications Table (Standard & XL Range)
Our SDS Max range (18mm shank) is manufactured to ultra-tight tolerances to ensure a 100% circular hole, meeting the strict safety requirements for heavy-duty mechanical and chemical anchoring.

3. Engineering Superiority: Why Professionals Choose Us
Progressive Flute Geometry (PFG)
To match the massive impact energy of SDS Max hammers, our bits feature a Progressive Helix.
-
Variable Core Thickness: The core diameter increases toward the shank, providing maximum torsional stability and preventing the bit from snapping during high-torque rebar strikes.
-
Accelerated Dust Displacement: The flute volume expands outward, creating a vacuum effect that extracts heavy debris 40% faster than standard straight-flute bits.
Vacuum-Heat-Treated 40Cr Alloy Stem
Every bit is forged from premium 40Cr alloy steel and undergoes a proprietary vacuum tempering process.
-
Elasticity vs. Rigidity: This treatment allows the bit to flex slightly under massive vibration without fracturing—essential for deep-hole drilling (up to 1000mm).
-
Fatigue Resistance: Shot-peened surface treatment creates a work-hardened layer that resists the formation of stress cracks.
High-Density YG8C Carbide with Auto-Welding
We utilize specialized YG8C grade carbide (HRC 89-91) joined to the body via a fully Automated Induction Welding process.
-
Thermal Endurance: The bond remains stable at temperatures up to 900°C, preventing tip-loss in high-friction environments.
-
Shock Absorption: Symmetrical head design ensures even distribution of impact forces, protecting the carbide from brittle fracturing.
4. Global Market Suitability & Logistics
-
Regional Optimization:
-
Middle East: Sand-blasted and oil-treated surface for maximum resistance to salt-air corrosion.
-
Russia & CIS: Engineered with low-temperature resilience to prevent brittleness in sub-zero site conditions.
-
Europe: Fully compliant with DIN 8039 and ISO 5468 safety standards.
-
-
B2B Customization (OEM): Precision Laser Etching for brand logos, metric/inch sizes, and localized technical markings directly on the shank.
-
Industrial Packaging: Heavy-duty, oil-resistant PVC tubes with reinforced caps for individual bits or custom contractor sets.
5. FAQ (Professional Procurement)
Q: Can these bits drill through rebar continuously?
A: Yes. Our 4-Cutter and Multi-Cutter designs are specifically engineered to slice through rebar without jamming, protecting the operator from sudden torque kickback.
Q: Will this fit my POWER TOOLS FOR THIS SDS Max hammer?
A: Absolutely. Our SDS Max shanks are precision-machined to international 18mm standards, ensuring a perfect fit with all professional high-joule rotary hammer brands.
Q: Do you support custom lengths for infrastructure projects?
A: We stock lengths up to 1000mm (1 meter). For bulk orders, we can manufacture custom lengths to meet specific project requirements.
