L3060CF-25B Extended Hard Rock Rotary Drilling Bullet Tooth
Product Overview
The L3060CF-25B Extended Hard Rock Rotary Drilling Bullet Tooth is a high-performance conical cutting tooth designed for hard rock drilling, deep foundation piling, trenching, and challenging geological conditions.
As part of the Extended Hard Rock Rotary Drilling Teeth series, the L3060CF-25B combines an extended gauge design, optimized fluted body structure, and an oversized tungsten carbide insert to deliver superior penetration performance and long operating life.
Featuring a premium Ø25mm tungsten carbide tip, this rotary drilling tooth provides excellent impact resistance, fracture toughness, and thermal stability during aggressive rock cutting operations.
The CF (Clearance Fluted) body design improves debris evacuation, reduces drilling resistance, and helps maintain smooth rotation in demanding ground conditions.
Built with a reinforced Ø60mm head, standard Ø30mm shank and Ø38mm step collar, the L3060CF-25B features an extended 88mm gauge length and 148mm overall length, providing increased cutting clearance and improved drilling efficiency.
Manufactured from forged 42CrMo alloy steel, this rotary drilling tooth delivers high strength, durability, and reliable performance for professional foundation drilling contractors worldwide.
