Stones 1 Inch Sds Hammer Drill With Milled Flutes And Auto-Welded Tip
Product Innovation: The Milled Flute Advantage
In the world of professional construction, not all drill bits are created equal. While standard bits use rolled flutes, our Precision Milled Flute Series is CNC-machined from solid alloy steel. This architectural difference provides a perfectly smooth internal helix, reducing the resistance of dust flow.
Combined with our Auto-Welded YG8C Carbide Tip, this bit offers a seamless fusion of speed and strength, specifically designed for the high-impact energy of modern rotary hammers.
Technical Precision Chart (Metric)
Our manufacturing process adheres to ISO 5468 standards, ensuring every bit delivers a perfectly circular hole—essential for the load-bearing integrity of chemical and mechanical anchors.

Core Advantages for Professional Contractors
Auto-Welded Fusion Technology
Unlike traditional brazing, our Auto-Welded Tip technology creates a molecular bond between the carbide and the steel body.
-
Impact Resilience: The tip will not "pop off" even when hitting high-density aggregates or steel rebar.
-
Thermal Stability: Maintains cutting efficiency at temperatures up to 900°C, preventing the tip from glazing over.
Optimized Dust Evacuation Flutes
The high-angle milled helix provides a larger internal volume for debris. This creates a "vacuum effect" that extracts dust 35% faster than standard bits, keeping the drilling site clean and the bit cool.
Anti-Vibration 40Cr Steel Body
We use a specialized 40Cr Alloy Steel that has been vacuum-quenched. This allows the bit to flex slightly under the massive vibration of a rotary hammer without snapping, protecting both the operator and the power tool's gearbox.
Specialized Regional Applications
-
Russia & CIS: Engineered to maintain toughness in sub-zero site temperatures, preventing the steel from becoming brittle.
-
Middle East: Sand-blasted finish provides high resistance to salt-air corrosion and desert humidity.
-
Europe: Fully compliant with DIN and ISO safety standards for structural rebar drilling.
Logistics & Retail Solutions
-
Packaging: Heavy-duty square PVC tubes (Industrial Grade) or Euro-hole hang-tags (Retail Grade).
-
OEM Customization: Precision Laser Etching for brand logos, sizes, and localized technical markings (English/Russian/Arabic).
-
Shipping: Moisture-proof palletization for long-distance rail or sea freight.
FAQ (Market Focused)
Q: How does the "Milled Flute" improve my cost-per-hole?
A: Milled flutes reduce the friction load on your drill's motor. This means less energy is lost to heat, and more energy is used for penetration, allowing the bit to last up to 40% longer than budget alternatives.
Q: Can I use this bit in natural granite?
A: Yes. The YG8C carbide grade is rated for hard natural stone. For the best results in granite, we recommend a medium-pressure "pecking" motion to clear the hard aggregate.
Q: Are these bits compatible with SDS Plus and SDS Max?
A: This specific chart covers the SDS Plus (10mm shank) range. We have a parallel series for SDS Max (18mm shank) for larger industrial demolition hammers.
