Compatibility and Required Interfaces
Rock drill and shank adapter
High-capacity top-hammer system
Confirm percussion equipment, shank adapter, rod/coupling and bit as one system.
Provide current component identities when replacing another supplier.
Threaded Bit Face and Connection
Large-hole T51 configuration control
Face, skirt, gauge protection, buttons and flushing are selected around the required diameter and formation.
Buyer value
Supports predictable interface matching and a configuration aligned with hole-cleaning and withdrawal demands.
Selection condition
Actual penetration and life depend on equipment condition, parameters and ground.
Application Scenarios
- Large-hole bench and production drilling
- Quarry and open-pit drilling
- Underground development requiring T51 drill strings
Confirm Before Ordering
Configuration Inputs
- Required hole diameter and drilling objective
- Exact T51 rod/coupling identity and rig or rock-drill model
- Face, body/skirt, button and flushing preference
- Rock hardness, abrasiveness, fracturing and hole depth
- Quantity, destination, inspection and packing requirements
Operating Limits
- Do not substitute T51 with another thread family by name or diameter alone
- Industry-reference diameters are not a PerfoMax availability promise
- Performance depends on the complete drill string, equipment condition, settings and formation
- Final configuration is controlled by the written quotation or approved drawing

Frequently Asked Questions
Which diameters are commonly seen in T51 catalogs?
Public catalog examples include drilling-bit diameters from 76 to 127 mm. PerfoMax will confirm the offered diameter and complete configuration.
Is T51 interchangeable with T45?
No direct interchangeability should be assumed. Confirm the full thread and shoulder interface and the complete drill string.
Why might a retrac T51 bit be selected?
Retrac bodies are considered where fractured ground or unstable hole walls make withdrawal and gauge management more demanding.
What operating information is needed?
Provide rig and rock-drill model, hole diameter/depth, formation, rotation/feed/percussion settings, flushing capacity and current wear pattern.
How are buttons and flushing confirmed?
They are confirmed together with face geometry, skirt and hole-cleaning requirements in the quotation or controlled drawing.
Matched Top-Hammer Threaded System
A complete T51 top-hammer system combines the rock drill and shank adapter, coupling, T51 rod, matched button bit and adequate flushing.
