Technical DataCore Specifications
- Shank Type: SDS Plus (10mm diameter, 4-groove interface) for light to medium-duty rotary hammers (≤5kg)
- Diameter Range: 4-26mm (1/8″-1″) for standard applications
- Length Range: 110-600mm (4″-24″) depending on depth requirements
Material & Construction
- Cutting Tip: Solid tungsten carbide (YG8/YG8C) with hardness HRC 90+
- Body: Chromium-nickel-molybdenum steel alloy with heat treatment
- Attachment: Vacuum brazed carbide tip for maximum heat resistance
Design Features
- Cross Tip: 4 cutting edges (90° angles) with self-centering point
- Flutes: S4 (5.4×) for 20% faster dust removal
- Reinforcement Guard: Special geometry prevents jamming when hitting rebar
- Tip Angle: 130° point angle for efficient penetration in hard materials
Performance Parameters
- Ideal Applications: Concrete, brick, block, stone, reinforced concrete
- Lifespan: 5-10× longer than standard bits in concrete
- Max. Operating Temp: 600°C (prevents softening during extended use)
- Recommended RPM: 800-2000 (hammer drill mode)
Advantages1. Precise Drilling Performance
- Self-centering design eliminates bit “walking” for accurate hole placement
- Produces near-perfect round holes for easier anchor insertion
- 4 cutting edges create uniform holes with ±0.2mm precision
2. Unmatched Rebar Resistance
- Cross geometry prevents locking when encountering reinforcement
- Maintains cutting efficiency even in heavily reinforced concrete
- Special “rebarsafe” design reduces bit breakage by 70%
3. Enhanced Durability
- Carbide construction maintains sharpness through 1000+ holes in concrete
- Heat-treated body resists bending under extreme loads
4. Maximum Productivity
- 4-flute design evacuates debris 3× faster, reducing heat buildup
- Reduces vibration by 50%, minimizing operator fatigue
- Drills through concrete 30% faster than standard bits
5. Versatile Compatibility
- Works with all SDS Plus rotary hammers (≤5kg)
- Ideal for both professional construction and DIY projects
- Handles multiple materials (concrete, brick, stone, block) with one bit
