34mm Diameter 7° Tapered Connection Ballistic Shape Carbide Tips Ball Tooth Drill Bit For Hard Rock Drilling
In 2026's fast paced mining, tunneling, and quarrying industries, drilling speed, durability, and cost efficiency define project success. For professionals tackling medium-hard to hard rock formations, the 34mm 7° Ballistic Shape Ball Tooth Drill Bit stands as a top tier solution — engineered to deliver unrivaled penetration, robust wear resistance, and seamless compatibility with modern drilling rigs.
Precision Engineered for Hard Rock Dominance
Every detail of this ballistic ball tooth bit is optimized for high-performance rock drilling, aligning with 2026's trends of smart drilling tools and high efficiency mining.
34mm Diameter : Versatility for Small Hole Drilling
The 34mm diameter strikes the perfect balance of coverage and agility. It's ideal for small-hole applications — including underground mining, granite quarrying, and tunnel support drilling — where precision and maneuverability are critical. Whether you're working on gold mines, coal mines, or geothermal projects, this size fits most standard jackhammers and air leg drills, ensuring broad compatibility.
7° Tapered Connection : Seamless Stable Drilling
The 7° taper angle is a gold standard in 2026's rock drilling tools. It enables:
Firm Locking: Snug fit with tapered drill rods, eliminating wobble even in high vibration hard rock conditions
Easy Removal: Quick bit swaps to minimize downtime, a key priority for high productivity drilling operations
Max Energy Transfer: Efficiently transmits hammer impact energy to the rock, reducing power waste and boosting drilling speed
The standout feature — ballistic (parabolic) shape tungsten carbide tips — is engineered for aggressive rock fracturing. Unlike spherical tips that spread force over a wide area, ballistic tips concentrate impact energy into a small contact area, creating micro fractures in the rock for 25% faster penetration than standard ball tooth bits.
Premium Alloy Steel Body : Built to Last
The bit body is forged from high strength 45CrNiMoV alloy steel, heat treated for maximum toughness and corrosion resistance. This rugged construction withstands extreme drilling pressures and harsh job site conditions, ensuring a service life of 100 - 200 hours — far longer than low cost generic bits. Two front water holes and one side water hole optimize flushing, clearing debris fast to prevent bit overheating and ensure clean, straight holes.
Key Advantages
Blazing Fast Penetration for High Productivity
Ballistic tips' concentrated force cuts through medium hard rock at 0.5 - 1.5 m/min, outperforming spherical and cross bits in speed. For quarries and mines prioritizing drilling efficiency, this translates to more meters per shift and lower labor costs — critical for 2026's cost sensitive projects.
Optimized for 2026's Hottest Drilling Trends
Green Mining Compatibility : Durable, long life design reduces bit replacements and waste, aligning with eco friendly mining and HSE standards.
Smart Drilling Ready : Works seamlessly with AI powered drill rigs, delivering consistent performance for data driven drilling operations.
Strategic Mineral Exploration : Perfect for drilling in lithium, cobalt, and rare earth mineral mines.
Cost Effective Low Maintenance
Long lasting carbide tips and a tough steel body minimize frequent replacements, cutting operational costs. The 7° taper design simplifies installation and removal, reducing maintenance time. For small to mid scale drilling contractors, this bit offers unbeatable ROI — high performance at a reasonable price point.
Wide Application Scenarios
Versatile performance across multiple industries and rock formations, making it an ideal choice for diverse drilling operations and project requirements.
Application Areas
Mining
Gold, coal, and metal ore mines (medium hard rock formations)
Quarrying
Granite, marble, and limestone extraction
Construction
Tunnel boring, road cut blasting, and foundation drilling
