3060EN-22B Fluted Reinforced Hard Rock Rotary Drilling Bullet Tooth
3060EN-22B 带凹槽的加固硬质岩石旋转钻钻头

Product Overview

The 3060EN-22B Fluted Reinforced Hard Rock Rotary Drilling Bullet Tooth is a high-performance rock cutting tooth designed for medium-weathered granite, sandstone, limestone, gravel layers, and challenging foundation drilling conditions.

As part of the Hard Rock Rotary Drilling Teeth series, the 3060EN-22B features an enhanced dual fluted and ribbed head design, improving rock chip evacuation while reducing cutting resistance during rotary drilling operations.

Built with a standard Ø30mm shank system and Ø38mm step collar, this rotary drilling tooth features a reinforced Ø60mm protective shoulder, 75mm gauge length, and 135mm overall length.

The optimized body structure combines angled clearance flutes, raised flow ribs, and a high-toughness Ø22mm tungsten carbide insert to achieve efficient penetration, stable rotation, and extended tool performance in demanding geological conditions.

Manufactured from forged 42CrMo alloy steel, the 3060EN-22B provides excellent mechanical strength, wear resistance, and reliable operation for professional foundation drilling contractors worldwide.
