DTH Hammer Selection Guide

DTH Hammer Selection Guide — Choose by Hole Size, Shank, Pressure and Air Supply

Model / SKU:PFM-DTH-HAMMER

Series selection guide for matching DTH hammer class, bit shank, top-sub thread, hole diameter and compressor output.

This page helps buyers select a DTH hammer system rather than presenting one fixed model. Final configuration is confirmed from hole diameter and depth, rock condition, rig, compressor flow and pressure, bit shank and drill-pipe thread.

  • Separates hammer-class selection from final model confirmation
  • Checks bit shank and top-sub thread before quotation
  • Compares CIR90 and CIR110 selection roles
  • Requires compressor flow at operating pressure, not pressure alone
  • Supports complete-system matching of hammer, bit, pipe and spares

Compatibility and Required Interfaces

System Interface

Model-specific bit shank and top-sub thread

Hammer, bit, pipe and compressor must be confirmed as one system

CIR90 and CIR110 components must not be assumed interchangeable. Confirm the exact bit shank, top-sub thread and available compressor flow before quotation.

Design and Performance

System-Based DTH Hammer Selection

Selection uses hole diameter and depth, rock condition, rig, compressor flow and pressure, bit shank and drill-pipe connection rather than model name alone.

Buyer value

The buyer receives a configuration that can be checked for physical connection, air demand and application fit before ordering.

Selection condition

Final configuration remains subject to the signed quotation or technical agreement.

Application Scenarios

  • Mining blast-hole drilling
  • Quarry production drilling
  • Water-well and geothermal drilling
  • Foundation and rock-socket drilling

Frequently Asked Questions

Why is this page not tied to one fixed DTH hammer specification?
Because hammer selection depends on the complete drilling system. PerfoMax confirms the hole requirement, rock, rig, compressor, bit shank and pipe thread before assigning the final model and configuration.
