Wave segments Sintered Diamond Core Drill Bits

Technical Data

1. Dimensions: Engineering models: outer diameter 57-356mm; daily-use small models: 4-78mm (total length 49-54mm); large long bits up to 5 inches. Wave segments: 24×3.5×13mm (large-diameter bits thicken to 24×5.5×13mm); segment quantity: 5 pieces (57mm) to 32 pieces (356mm).
2. Shank: Small/medium bits: common shank diameter 10mm; 16mm-diameter bits: 14mm shank; M14 threaded shank for professional equipment (fits hand drills, drill presses, engineering drilling machines).
3. Material & Manufacturing: Wave segments: diamond grit + metal matrix; combined with steel drill body via hot-press sintering (strengthened by high-frequency/laser welding). Standard models: 10mm diamond working length.
4. Operation: Mainly wet drilling (water for lubrication/cooling); small bits not for hammer drills; large road/bridge bits adapt to high-speed drilling (fits materials with different compressive strengths).

Advantages

1. High Efficiency: Wave segments expand contact area, speeding up drilling and facilitating debris discharge.
2. Strong Durability: Sintered diamond grit distributes evenly, stays sharp long; service life 3-5× that of brazed tools, 10-20× that of coated bits.
3. High Precision: Sintered structure ensures good concentricity; wave segments reduce drilling torque.
