FAQ’S

1. How do I choose the right hammer for my application?
  • FDG60DI/FDS70DI – Best for medium to large boreholes in mining and construction.

  • FDS47DI/S45S4 – Suitable for smaller diameter holes in various geological conditions.

  • SDM82(B) – Ideal for deep-hole drilling and heavy-duty applications.

  • WIN35DH – Best for precision drilling in smaller boreholes.

Valveless hammers, like the FDS47DI and FDS70DI, provide higher impact efficiency, fewer moving parts, and lower maintenance requirements.

  • Use proper air pressure settings to avoid excessive wear.
  • Inspect components regularly, especially pistons and wear sleeves.
  • Lubricate moving parts to reduce friction and overheating.

Uttam Blastech hammers are compatible with D8 and DHD3.5 shank

Yes! FDG60DI, SDM82(B), and FDS70DI are well-suited for deep-hole drilling in water well and geothermal projects.
