Compatibility and Required Interfaces
Rig-side interface
Rock drill, shank adapter and rod system
Confirm the complete string rather than the bit alone.
Adapters change the system configuration and do not make thread families directly interchangeable.
Threaded Bit Face and Connection
Balanced T45 drilling configuration
Body style, face, gauge protection, button layout and flushing are selected together.
Buyer value
Supports a configuration suited to penetration, hole control, cleaning and withdrawal priorities.
Selection condition
Final results depend on the matched drill string, operating settings and formation.
Application Scenarios
- Quarry and bench drilling
- Underground development and tunneling
- Construction drilling and production holes
Confirm Before Ordering
Configuration Inputs
- Required hole diameter and drilling objective
- Exact T45 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 T45 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
What diameter range is commonly referenced for T45 button bits?
Public catalog examples include 66 to 102 mm drilling bits, with larger diameters often appearing as separate reaming products. PerfoMax will confirm the offered configuration.
Can a T45 bit replace T38 or T51?
Not directly based on family name or appearance. The thread, shoulder, rod and coupling system must be confirmed.
When is a retrac body considered?
Retrac configurations are commonly reviewed where broken ground or hole-wall instability makes bit withdrawal more difficult.
Which face and button profile should I request?
Send formation hardness, abrasiveness and fracturing, hole objective, drilling equipment, flushing conditions and current bit performance.
What controls the final supplied configuration?
The accepted quotation and approved configuration reference or drawing control diameter, body, face, buttons and flushing.
Matched Top-Hammer Threaded System
A complete T45 top-hammer system combines the rock drill and shank adapter, coupling, T45 rod, matched button bit and adequate flushing.
