Elevate your drilling performance with our Professional SDS Plus 4-Cutter Cross Head Drill Bits. Specifically engineered for high-torque rotary hammers, these bits are the ultimate solution for drilling into heavily reinforced concrete, natural stone, and dense masonry. Unlike standard 2-cutter bits that often jam or "walk" when hitting resistance, our symmetrical 4-cutter geometry ensures a smooth, continuous drilling experience with maximum precision.
True 4-Cutter Cross Head Geometry: The solid tungsten carbide head features four independent cutting edges. This X-shape design prevents the bit from seizing or snapping when it encounters steel rebar, providing a 30% longer service life in reinforced structures.
Precision Centering Tip: Equipped with a sharpened "Power-Point" centering tip, this bit allows for immediate spot-drilling without slipping. It ensures every hole is perfectly centered, which is critical for the load-bearing integrity of chemical and mechanical anchors.
Premium YG8C Tungsten Carbide: We use high-density YG8C grade carbide, vacuum-brazed at temperatures exceeding 1,100°C. This industrial-grade material maintains its hardness even under the extreme thermal stress generated by deep-hole drilling in high-PSI concrete.
Hardened 40Cr Alloy Steel Body: The bit body is forged from premium 40Cr alloy steel, optimized through a proprietary heat-treatment process to balance structural rigidity with the flexibility needed to absorb high-frequency hammer impacts.
Rapid Dust Evacuation: The high-volume K-Type Double Flute effectively channels dust away from the tip. This reduces friction, prevents heat buildup, and allows for faster penetration speeds in deep-hole applications.
Universal SDS Plus Compatibility: Manufactured to strict ISO 5468 and DIN 8039 standards, our shanks offer 100% compatibility with all SDS Plus rotary hammers .
Anti-Vibration Engineering: The balanced 4-cutter head significantly reduces vibration levels, protecting the operator from fatigue and extending the lifespan of the power tool's internal mechanism.
Structural Anchoring: Perfect for installing rebar, heavy machinery anchors, and structural steel fixings.
Infrastructure Projects: Widely used in bridge construction, tunneling, and high-rise commercial builds across Europe and the Middle East.
Renovation & Demolition: Reliable performance in the aged, high-density concrete panels frequently found in Russia and CIS regions.
We offer high-durability packaging suited for international transit. From individual PVC tubes with Euro-hole hangers to professional 7-piece sets in ABS cases, our products are retail-ready. For bulk orders, we provide reinforced, moisture-proof cartons palletized for sea or rail freight to Europe and Russia.
