Send rig and rock-drill markings, known shank adapter coupling and bit references, available evidence, the selected current length and operating context. Choose a separate inquiry if MF is required.

Technical Review Scope

Configuration and Quotation Guidance

T45 male–male extension-rod configuration inquiry. This page is limited to the MM end style and four length references. It does not represent an MF speed rod or a complete orderable rod configuration.

Configuration identity: the length codes on this page are inquiry references for T45 male–male extension rods, not complete orderable SKUs. Confirm the overall or effective length basis, rod body, flushing bore, matching T45 shank adapter, coupling and bit, and controlled drawing revision before technical approval. An MF speed rod is a separate configuration and must receive a different approved configuration ID rather than reuse a length code from this page.

Current inquiry references

Information to confirm

  • Rig or rock-drill model and matching T45 shank adapter.
  • MM end style, overall or effective length basis and rod-body requirement.
  • Flushing bore or an engineering-proposal-required state.
  • Matching T45 coupling and bit.
  • Current drawing, measurements or replacement-part photos.

MF request boundary

If an MF speed rod is requested, the current MM length code must be cleared from the proposed order identity. The MF request must enter a separate configuration review and receive its own approved configuration ID.

Engineering and quotation outputs

Before technical approval, the controlled drawing must return the end style, length basis, rod body, flushing bore, matching shank adapter, coupling, bit, mass, tolerance and drawing revision. Buyer uncertainty may enter an inquiry but must not be converted into a guessed supplied value. Every technically approved T45 MM configuration must receive its own approved configuration ID; the current length reference must not be the sole order identity.

Inspection and NDT boundary

NDT is not included by default. If an NDT requirement is requested and expressly accepted in the written quotation, the method, applicable standard and edition, inspected quantity or batch scope, acceptance criteria or level, report requirement and lot traceability must be stated. This inquiry page does not promise an NDT method or batch coverage.

Compatibility and Required Interfaces

Coupling sleeve

T45 coupling sleeve

T45 thread and matching body/end geometry

Check coupling wear and thread grease practice in service.

Top-hammer drill string

T45 shank adapter and bit system

Compatible T45 interfaces across shank, rods, couplings and bit

Threaded Drill-String Design

Impact, Rotation and Flushing Path

The rod body and T45 connections carry percussion and torque while the central passage delivers the selected flushing medium.

Buyer value

Correct end style, straightness and thread fit support energy transfer, hole control and connection life.

Selection condition

Confirm thread, body section, bore, length, straightness criteria and the complete drill-string interface.

Application Scenarios

  • Top-hammer bench drilling
  • Quarry production drilling
  • Civil and surface construction drilling

Frequently Asked Questions

Is this T45 page for MF speed rods?
The listed default is a male–male extension rod. If you need an MF speed rod, state the exact end style and provide the current rod or drawing so it can be quoted separately.
What should I send for a T45 rod quotation?
Provide drifter or shank-adapter model, current rod and coupling details, thread, end style, body section, flushing bore, length, hole diameter, rock conditions and quantity.

Matched Top-Hammer Threaded System

A matched T45 string combines the shank adapter, coupling sleeve, T45 extension rods and drill bit. Confirm end style, body section and flushing path across the full string.

This page identifies an MM male–male extension rod only. An MF request clears the current MM length code and needs a separate approved configuration ID. Technical review must return the full drill-string configuration and controlled drawing revision.
