Product Description
44mm Diameter 4-Blade Cross Drill Bit for Efficient Chip Removal and Anti-Jamming Rock Drilling
The 44mm cross-type drill bit is a high-efficiency impact drill bit featuring a cross-shaped (four-bladed) carbide cutting head. Designed for use with tapered drill rods and rock drills, it delivers optimal performance in medium-hard to hard, fractured, or heavily jointed rock formations.
Material:
42CrMo alloy steel with quenching and tempering treatment
Weight:
0.8 kg
Rock Compatibility:
Medium-hard to hard, fractured, or heavily jointed formations
Core Advantages
Superior Rock Adaptability: Cross-shaped cross-section design evenly distributes impact force, preventing stress concentration and reducing drill bit jamming and edge chipping
Efficient Chip Evacuation: Four-blade design creates natural channels for quick removal of rock powder, preventing borehole clogging and overheating
Balanced Wear & Extended Service Life: Symmetrical cutting edges ensure even wear, preventing eccentric drilling and maximizing operational lifespan
Enhanced Durability: High toughness and fatigue resistance from advanced heat treatment processes
