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

1

Premium Tungsten Carbide Inserts

Equipped with high-density carbide buttons (spherical or ballistic profiles) that provide superior resistance against severe abrasive wear.

2

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.

3

Multiple Taper Angles Available

Compatible with standard 7°, 11°, and 12° tapered drill rods for easy assembly and secure locking without slippage.

4

Efficient Hole Flushing

Designed with optimized center and side flushing holes to clear rock cuttings rapidly, preventing bit jamming and premature wear.

5

Cost-Effective Efficiency

Offers an exceptional cost-per-meter ratio through fast penetration rates, extended service life, and ease of replacement.
