Stop Bit Jamming Before It Stops Your Drilling
In fractured or unstable formations, drilling performance is not determined by penetration rate alone.
A conventional flat-face button bit may perform well while drilling but can become difficult to retract when broken rock collapses around the bit. This can increase withdrawal resistance, interrupt drilling, increase equipment downtime, and raise operating costs.
Retrac Button Bits are designed to address this specific challenge.
| Conventional Button Bits | Retrac Button Bits |
|---|---|
| Higher risk of sticking in fractured formations | Back-reaming skirt body helps reduce sticking |
| Limited clearance during withdrawal | Designed for smoother retraction |
| Broken rock can accumulate around the bit | Skirt geometry supports more effective rock removal |
| Drilling interruptions can increase operating costs | More reliable drilling cycles |
| Performance can deteriorate as formations become unstable | Designed for demanding fractured and unstable rock |
The Result?
Less time fighting the hole. More time drilling.
The Retrac design provides additional clearance during withdrawal and helps the bit move more smoothly through fractured or unstable ground.
4 Technical Advantages That Improve Drilling Performance
Back-Reaming Skirt Body Design
The defining feature of a Retrac Button Bit is its specialized skirt body geometry.
The rear section of the bit is designed to provide improved clearance during withdrawal and reduce the tendency of broken or fractured rock to lock the bit in the hole.
Premium Tungsten Carbide Buttons
Button quality directly affects rock penetration, wear resistance, and drilling consistency.
Our Retrac Button Bits use premium tungsten carbide buttons selected for demanding top hammer drilling conditions.
Depending on the application, button geometry can be optimized to balance:
- Penetration rate
- Wear resistance
- Impact durability
- Rock-breaking efficiency
- Service life
The objective is not simply to maximize initial penetration. The goal is to maintain useful drilling performance throughout the working life of the bit.
Improved Hole Alignment and Straightness
Hole deviation becomes increasingly important in long-hole drilling.
Poor alignment can affect:
- Explosive placement
- Rock bolting accuracy
- Drilling productivity
- Hole utilization
- Overall project cost
Retrac Button Bits are engineered to maintain stable contact with the rock formation while supporting consistent drilling geometry.
Combined with correct drilling parameters and compatible top hammer drilling tooling, the design helps operators achieve more consistent hole straightness, particularly in demanding long-hole applications.
Optimized Flushing for Faster Rock Removal
Efficient flushing is essential for maintaining penetration performance.
When cuttings are not removed effectively, they can remain around the bit, interfere with rock breaking, increase regrinding, and reduce drilling efficiency.

Retrac Button Bit Selection Guide
Choosing the right Retrac Bit requires more than selecting a diameter.
The correct combination of thread, diameter, face design, button configuration, rock formation, and drilling parameters is essential for achieving reliable performance.
Thread Options
We supply Retrac Button Bits for common top hammer drilling configurations:
R32, T38, T45, T51,T60, ST58 & ST68
Available bit diameters: 45–152 mm
Actual selection should be based on the rock formation, drill rig, rock drill, drill rod, hole diameter, and required drilling depth.
Choose the Right Bit Face Design
Flat Face Retrac Button Bits
Flat Face designs provide a robust and versatile configuration for a wide range of rock formations.
They can be considered when:
- Rock conditions are relatively consistent
- General-purpose drilling performance is required
- Durability is a priority
- A balanced penetration/wear profile is needed
Drop Center Retrac Button Bits
Drop Center designs concentrate the initial rock-breaking action toward the center of the hole.
They can be advantageous when:
- Faster penetration is required
- Formation conditions allow a more aggressive cutting profile
- Efficient center-rock breaking is important
- Drilling productivity is a major priority

Spherical vs. Ballistic Buttons
Button geometry also affects drilling behavior.
Spherical Buttons
Spherical buttons provide strong resistance to impact loading and are commonly selected when durability and wear resistance are important.
Suitable considerations:
- Hard and abrasive rock
- High-impact applications
- Longer service-life requirements
Ballistic Buttons
Ballistic buttons provide a more aggressive penetration profile and can be considered when higher penetration performance is prioritized.
Suitable considerations:
- Faster drilling requirements
- Medium-to-hard rock
- Applications where penetration rate is a key KPI
The optimum button configuration depends on the formation and drilling parameters rather than diameter alone.
Built for Difficult Top Hammer Drilling Conditions
Retrac Button Bits are particularly suitable for applications where conventional bit designs may experience withdrawal or stability problems.
Mining
Improve drilling reliability in fractured and broken formations while maintaining productive drilling cycles.
Tunneling
Support consistent hole drilling where hole deviation, withdrawal reliability, and drilling efficiency are critical.
Quarrying
Maintain productive drilling performance across changing rock conditions and reduce unnecessary bit replacement.
Long-Hole Drilling
Improve hole straightness and withdrawal reliability where longer drilling distances increase the consequences of deviation or sticking.
Reduce Cost Per Meter — Not Just Bit Price
A lower purchase price does not necessarily mean lower drilling cost.
For contractors, the more meaningful metric is often:
Cost Per Meter = Total Drilling Cost ÷ Meters Drilled
A Retrac Button Bit can contribute to lower CPM by combining:
The right question is not:
“How much does the bit cost?”
Ask instead:
“How many productive meters can I drill before replacing it?”
Why Choose Our Retrac Button Bits?

Controlled manufacturing processes help maintain dimensional consistency, button positioning, and overall bit quality.
OEM & Private Label Support
Distributors and drilling tool suppliers can request customized branding, packaging, and product configurations.
Technical Selection Support
Provide your drilling parameters and current operating conditions, and our technical team can help identify a suitable Retrac Button Bit configuration.
FAQ
Retrac Button Bits Information
A Retrac Bit is particularly worth considering when drilling in fractured, broken, or unstable rock where bit withdrawal and sticking are recurring problems.
The specialized back-reaming skirt body provides additional clearance during retraction and helps reduce the risk of the bit becoming locked by loose or collapsing rock around the hole.
If your main problem is simply low penetration in competent rock, a conventional button bit may be more appropriate depending on the application.
Our Retrac Button Bits are available with R32, T38, T45, T51,T60, ST58 & ST68 thread configurations, with drilling diameters from 45 mm to 152 mm.
The correct combination depends on your rock drill, drill rod, required hole diameter, drilling depth, rock formation, and operating parameters.
The choice depends primarily on rock formation and drilling priorities.
A Flat Face design provides a balanced and robust configuration for many general drilling conditions.
A Drop Center design can provide a more aggressive center-rock breaking action and may be preferred when penetration performance is a higher priority.
For an accurate recommendation, provide your rock type, hardness/abrasiveness, hole diameter, drilling depth, rock drill model, and current bit configuration.
