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
Ballistic Shape Carbide Tips : Speed Strength Redefined
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.
