Compatibility and Required Interfaces
Rock drill and shank adapter
Complete rig-side top-hammer interface
Confirm rock drill model, shank adapter, coupling, rod and bit as one system.
Provide current markings or drawings for replacement review.
Threaded Bit Face and Connection
Configuration-led cutting structure
Face geometry, skirt, button profile/layout and flushing are selected as one configuration.
Buyer value
Helps balance penetration, gauge control, hole cleaning and withdrawal for the stated drilling condition.
Selection condition
Performance depends on correct drill-string matching, operating parameters and rock condition.
Application Scenarios
- Bench and production drilling
- Tunneling and underground development
- Quarrying, construction and general top-hammer drilling
Confirm Before Ordering
Configuration Inputs
- Required hole diameter and drilling objective
- Exact T38 rod/coupling identity and rig or rock-drill model
- Face, skirt, button and flushing preference
- Rock hardness, abrasiveness, fracturing and hole depth
- Quantity, destination, inspection and packing requirements
Operating Limits
- Do not substitute T38, R38 or HL38 by family name 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 can be discussed for a T38 button bit?
Public top-hammer catalogs show T38 button-bit examples from 54 to 102 mm. Send the required hole diameter; PerfoMax will confirm the current configuration and availability in writing.
Can T38 replace R38 or HL38?
No automatic interchangeability should be assumed. Confirm the exact mating rod thread, shoulder and approved connection evidence.
Should I choose a standard or retrac body?
Standard bodies suit straightforward drilling conditions; retrac bodies can assist withdrawal in broken or collapsing ground. The final choice depends on hole condition, diameter and drill string.
What information is needed to select the face and buttons?
Provide rock hardness, abrasiveness, fracturing, hole diameter/depth, rig or rock drill, flushing medium and any current bit reference.
How is a repeat order controlled?
Use the previous PerfoMax quotation, approved drawing or configuration ID. The family name T38 alone is not sufficient for a repeatable order.
Matched Top-Hammer Threaded System
A complete T38 top-hammer system combines the rock drill and shank adapter, coupling, T38 rod, matched button bit and adequate flushing.
