1. Product Overview
The Q7-32mm taper button bit is a specialized drilling tool
designed for rock drilling and mining applications. Unlike a
conventional taper bit, it features button-shaped carbide inserts
(tungsten carbide buttons) embedded into the bit body for enhanced
durability and cutting efficiency in hard rock formations.
"Q7" : Likely denotes the series or design code.
"32mm" : Indicates the maximum diameter of the bit's tapered
section.

2. Key Features
Tapered Design : Gradual increase in diameter (e.g., from a smaller
pilot diameter to 32mm).
Carbide Buttons : Tungsten carbide inserts provide high abrasion
resistance for prolonged life in hard rock.
Material : Forged alloy steel body with heat-treated hardness for
impact resistance.
Threaded Shank : Typically features a tapered or threaded
connection (e.g., R32, T38, or other standard rock drill thread
types).
Flushing Holes : Allows for air or water flushing to remove drill
cuttings.
3. Applications
Mining & Quarrying : Drilling blast holes in hard rock (granite,
basalt, etc.).
Construction : Foundation drilling, tunneling, and demolition work.
Exploration : Core drilling or percussive drilling in geological
surveys.
4. Technical Specifications (Example)
PARAMETER: DETAILS
Bit Type: Tapered button bit
Diameter Range: Tapers up to 32mm
Shank Type: Tapered (e.g., T38, R32) or threaded
Button Count: Typically 4-8 inserts, depending on size
Material: High-grade steel body with tungsten carbide buttons
Flushing: Central or side flushing holes
5. Usage Guidelines
Drill Compatibility : Ensure compatibility with percussive rock
drills (e.g., jackhammers, down-the-hole hammers).
Rotation Speed : Optimize RPM based on rock hardness (lower for
harder formations).
Flushing : Use compressed air or water to keep the hole clean and
prevent overheating.
Maintenance : Regularly inspect buttons for wear and replace if
cracked or excessively worn.
6. Advantages Over Standard Bits
Longer Lifespan : Carbide buttons resist wear better than
steel-only bits.
Faster Penetration : Efficient cutting in abrasive rock.
Reduced Vibration : Stable performance in high-impact drilling.
