Core Features

· Lightweight High-strength Design
Made of 65Mn spring steel or 40Cr alloy steel, quenched and tempered to HRC 42-48 with bending strength ≥900MPa. Wall thickness 1.5-3mm, 20% lighter than traditional substrates, reducing inertia during drilling.

· Precision Welding Technology
Laser welding or high-frequency brazing ensures bonding strength ≥500MPa with weld width ≤0.15mm, maintaining stability at 3000-8000rpm to prevent segment detachment.

· Anti-vibration & Heat Dissipation

· Silencing Grooves: Ring grooves reduce drilling noise to ≤85dB;

· Heat Dissipation Holes: Axial holes with inner flow channels keep temperature below 150℃;

· Dynamic Balance: Residual unbalance ≤4g·cm, vibration amplitude ≤0.04mm at high speeds.

Application Scenarios

· Construction: Drilling ventilation/pipeline holes in concrete/brick walls, compatible with electric hammers and bench drills;

· Metal Machining: Deep-hole drilling for stainless steel/aluminum, diameter Φ30-Φ120mm, depth up to 300mm;

· Stone & Ceramic: Perforating marble/tiles, supporting dry/wet cutting with hole wall roughness Ra≤3.2μm.

Technical Parameters
