In the mining and quarrying industry, productivity is measured in meters drilled, operating costs, and machine uptime. Every hour of drilling affects production schedules, fuel consumption, labor costs, and ultimately, profitability.
For many years, conventional tungsten carbide button bits have been the standard choice for Down-The-Hole (DTH) drilling. However, when drilling highly abrasive rocks such as granite, carbide buttons wear quickly, requiring frequent bit replacement and increasing downtime.
Today, a new generation of drilling technology is changing the industry. PDC Buttons (Polycrystalline Diamond Compact Buttons) are helping quarry operators drill faster, reduce operating costs, and significantly extend bit life.
The PDC Button has become an excellent solution for Diamond DTH Bits used in granite quarries and aggregate production plants. If your operation is looking to reduce drilling costs while improving productivity, here's why the PDC button deserves your attention.
What Is a PDC Button?
A PDC Button is a superhard cutting element manufactured by bonding a layer of synthetic polycrystalline diamond to a tungsten carbide substrate using High Pressure High Temperature (HPHT) technology.
This unique combination provides the advantages of both materials:
- The diamond layer offers exceptional hardness and outstanding wear resistance.
- The tungsten carbide substrate provides high impact strength and structural support.
Compared with conventional carbide buttons, PDC buttons maintain a sharp cutting edge for a much longer period, making them ideal for demanding rock drilling applications.
Today, PDC buttons are widely used in:
● DTH drill bits
● Mining drill bits
● Quarry drilling
● Bench drilling
● Blast hole drilling
● Foundation drilling
● Construction drilling
Their superior durability has made them an increasingly popular choice for high-performance drilling tools.
The Challenge of Drilling Granite
Granite is one of the hardest and most abrasive rocks encountered in quarrying.
Although it is widely used for crushed stone, road construction, railway ballast, and concrete aggregates, granite presents significant challenges for drilling equipment.
Common problems with conventional carbide DTH bits include:
● Rapid button wear
● Reduced penetration rate
● Frequent bit replacement
● Increased downtime
● Higher drilling costs
● Lower overall productivity
Every bit change interrupts production, increases labor costs, and reduces equipment utilization.
For quarry operators, these hidden costs can be substantial.
Why the PDC Button Is Designed for Granite Quarry Applications
The PDC Button has been specifically developed for demanding drilling conditions such as granite aggregate plants and hard rock quarries.
Its optimized diamond layer and robust carbide substrate provide outstanding performance where conventional carbide buttons struggle.
When installed in Diamond DTH Bits, PDC buttons deliver significant improvements in drilling efficiency and operating costs.
1. Dramatically Longer Bit Life
One of the biggest advantages of PDC buttons is their exceptional wear resistance.
A traditional carbide DTH bit used in granite typically drills around 200 meters before requiring replacement. By comparison, a Diamond DTH Bit equipped with PDC Buttons can achieve 800 to 1,000 meters under comparable working conditions. This represents four to five times the service life of conventional carbide bits.
Longer bit life means:
● Fewer bit replacements
● Less downtime
● Higher machine availability
● Lower inventory requirements
● More continuous production
For quarry operators, longer service life directly translates into improved profitability.
2. Reduce Drilling Costs by Around 30%
Although Diamond DTH Bits may have a higher initial purchase price, the overall economics are far more favorable.Because the bit lasts significantly longer and requires fewer replacements, customers can reduce total drilling costs by approximately 30%.
Cost savings come from several sources:
● Lower bit consumption
● Reduced maintenance
● Less machine downtime
● Lower labor costs
● Improved production efficiency
Instead of evaluating only the purchase price, experienced quarry operators focus on cost per drilled meter—and this is where PDC button delivers outstanding value.
3. Increase Drilling Efficiency by Around 40%
Speed matters in every quarry.Every additional meter drilled per hour contributes directly to production output.Thanks to the superior cutting performance of polycrystalline diamond, Diamond DTH Bits equipped with PDC Buttons can improve drilling efficiency by approximately 40%.For operations running multiple drilling rigs, these productivity gains can have a significant impact on annual operating performance.
4. Stable Performance in Abrasive Granite
Granite continuously wears conventional carbide buttons. As buttons become rounded, drilling slows, vibration increases, and energy consumption rises.
PDC dome cutter maintains a sharp cutting surface much longer, resulting in:
● Consistent penetration rates
● Stable drilling performance
● Reduced vibration
● Lower energy loss
● Better hole quality
Stable drilling also reduces stress on the drilling rig and helps extend the service life of other components.
