36mm Tapered Button Bit
Compact Rock Drilling Tool for Small-Hole Mining, Quarrying, Tunneling, and Construction Operations
Product Overview
The 36mm Tapered Button Bit is an advanced rock drilling tool engineered for small-hole drilling in underground mining, quarrying, construction, and tunneling applications. Designed to connect seamlessly with tapered drill rods (typically 7°, 11°, or 12° taper angles), this compact drill bit is crafted from premium structural alloy steel and wear-resistant tungsten carbide inserts.
Featuring an optimized button placement and flushing configuration, the 36mm tapered bit maximizes impact energy transmission from handheld rock drills (pneumatic or hydraulic) into the rock face, delivering rapid penetration rates and long-lasting durability in soft-to-hard rock formations.
Main Applications
Dimensional Stone Quarrying
Clean and precise small-diameter hole drilling in granite, marble, and limestone quarries.
Underground Mining & Tunneling
Underground drifting, cross-cut opening, and face drilling operations.
Rock Bolting & Anchoring
Drilling anchor and bolt holes for rock slope stabilization and tunnel ceiling reinforcement.
Construction & Secondary Blasting
Utility trenching, road maintenance, and secondary boulder breaking in construction sites.
Key Features & Advantages
Premium Tungsten Carbide Inserts
Equipped with high-density carbide buttons (spherical or ballistic profiles) that provide superior resistance against severe abrasive wear.
High-Strength Steel Body
Machined from high-grade alloy steel and subjected to advanced heat treatment to resist fatigue and shock loads during heavy impacts.
Multiple Taper Angles Available
Compatible with standard 7°, 11°, and 12° tapered drill rods for easy assembly and secure locking without slippage.
Efficient Hole Flushing
Designed with optimized center and side flushing holes to clear rock cuttings rapidly, preventing bit jamming and premature wear.
Cost-Effective Efficiency
Offers an exceptional cost-per-meter ratio through fast penetration rates, extended service life, and ease of replacement.
