34mm Tapered Button Bits
,Quarrying Tungsten Carbide Button Bits
,Pneumatic Rock Drilling Bits OEM
Product Introduction
The 34mm Tapered Button Bit is a compact and durable rock drilling tool designed for use with compatible tapered drill rods and pneumatic rock drills. It is widely used for small-diameter drilling in quarrying, mining, tunneling, road construction and general excavation projects.
The bit body is manufactured from heat-treated alloy steel and fitted with wear-resistant tungsten carbide buttons. Its accurately machined taper socket provides a stable connection with the drill rod, transferring impact energy efficiently to the rock surface. Brighttop Global Co., Ltd. supplies 34mm tapered button bits in different taper angles, carbide button shapes, flushing configurations and button layouts to suit various drilling machines and rock formations.
Product Applications
Suitable for use with tapered drill rods, jackhammers and light pneumatic rock drilling machines.
Features and Advantages
1. Wear-Resistant Tungsten Carbide Buttons
The carbide buttons provide reliable impact resistance and wear performance, maintaining stable penetration in soft to medium-hard rock formations throughout extended drilling cycles.
2. Heat-Treated Alloy Steel Body
The bit body is manufactured from selected alloy steel and processed through controlled heat treatment to improve toughness, fatigue resistance and overall service life under high-frequency percussion.
3. Efficient Impact Energy Transfer
The precision-machined taper socket creates a secure connection between the button bit and tapered drill rod, reducing unnecessary energy loss and maximizing penetration efficiency.
4. Stable Drilling Performance
The balanced carbide button arrangement improves drilling stability, hole accuracy and penetration consistency, minimizing bit deviation during deep-hole operations.
5. Effective Flushing System
Central or side flushing holes remove rock cuttings from the borehole, reducing repeated crushing and maintaining drilling efficiency across various rock conditions.
6. Multiple Taper Angle Options
Available in 6°, 7°, 11° and 12° taper connections to match different tapered drill rods and drilling equipment configurations worldwide.
7. Different Carbide Button Shapes
Spherical and ballistic carbide buttons are available for different rock hardness levels and drilling speed requirements, allowing optimal configuration per application.
8. Customizable Production
Taper angle, button quantity, carbide shape, flushing-hole design, surface finish, logo and packaging can be customized according to customer specifications.

How to Select the Correct 34mm Tapered Button Bit
- Match the Taper Angle: The taper angle of the drill bit must match the taper angle of the drill rod. A mismatched connection may cause unstable drilling, premature wear or difficulty removing the bit.
- Confirm the Rock Formation: Ballistic buttons are suitable for faster penetration in softer formations, while spherical buttons provide better wear resistance in harder or more abrasive rock.
- Check the Flushing Design: Choose central or side flushing according to the rock drill, borehole depth and cuttings-removal requirements.
- Confirm the Drilling Equipment: Check the rock drill model, shank size, tapered rod specification and operating pressure before selecting the bit.
- Select the Correct Button Layout: The button arrangement affects penetration rate, hole accuracy, wear pattern and drilling stability.
Frequently Asked Questions
What is a 34mm tapered button bit?
A 34mm tapered button bit is a rock drilling bit with a nominal cutting diameter of 34 mm. It connects to a tapered drill rod and is normally used with pneumatic rock drilling equipment for mining, quarrying and construction applications.
Which taper angles are available?
Common taper angles include 6°, 7°, 11° and 12°. The selected angle must match the corresponding tapered drill rod for a secure and stable connection.
What is the difference between spherical and ballistic buttons?
Spherical buttons provide good impact resistance and wear life, especially in harder or abrasive rock. Ballistic buttons have a more pointed profile and may provide faster penetration in softer rock formations.
What rock can a 34mm tapered drill bit be used for?
It is commonly used for granite, limestone, sandstone and other soft to medium-hard rock formations. The carbide configuration should be selected according to rock abrasiveness and drilling conditions.
Can the button arrangement be customized?
Yes. Button quantity, button diameter, carbide shape and flushing-hole arrangement can be adjusted according to the required drilling performance and rock conditions.
Can you supply matching tapered drill rods?
Yes. Matching tapered drill rods and related rock drilling tools can be supplied according to the taper angle and drilling equipment specifications.
