Technical DataCore Specifications
- Shank Type: SDS MAX (18mm diameter) for heavy-duty rotary hammers >5kg
- Diameter Range: 12-50mm (1/2″-2″) for large holes in concrete
- Length Range: 200-1200mm (8″-48″) depending on application
Material & Construction
- Cutting Tip: Solid tungsten carbide (HRC 90+) for extreme hardness
- Body: Chromium-nickel-molybdenum steel alloy for durability
- Attachment: Vacuum brazed carbide tip for heat resistance
Design Features
- Cross Tip: 4 cutting edges (90° angles) with self-centering point
- Flutes: S4 (5.4×) or U-shaped for efficient dust evacuation
- Special Design: Active-centering tip for rounder holes in precision anchoring
Performance Parameters
- Ideal Applications: Reinforced concrete, granite, masonry, heavy construction
- Lifespan: 5-8× longer than standard bits in concrete with rebar
- Max. Operating Temp: 600°C (prevents softening during extended use)
Advantages1. Unmatched Power Transmission
- 18mm shank with 5-pit design delivers maximum impact energy (up to 100% power transfer)
- Perfect for industrial-grade applications requiring deep, large-diameter holes
2. Superior Drilling Performance
- Cross tip design creates 180° cutting diameter, doubling efficiency vs. standard bits
- Four symmetric cutting edges reduce vibration by 50%, minimizing operator fatigue
- Self-centering feature eliminates “walking” for precise hole placement
3. Reinforcement-Resistant Design
- Cross geometry prevents jamming when encountering rebar
- Maintains cutting efficiency even in heavily reinforced concrete
- Ideal for anchor installation where precision and durability matter
4. Enhanced Chip Management
- spiral flutes remove debris 3× faster
- Prevents clogging during continuous heavy-duty drilling
- Reduces heat buildup for extended tool life
5. Industrial-Grade Durability
- Carbide construction maintains sharpness through 1000+ holes in concrete
- Heat-treated body resists bending and deformation under extreme loads
- Ideal for professional construction, infrastructure projects, and demolition
