T38-Rod-Hex-MF-R32 Male-Female Hex Drifting Drill Rod (Hex 32 / R32 Speed Rod)

Premium T38 Male/Female Hexagonal Drifting Drill Rod (Hex 32)

Optimized for Tunneling Rods & Drifting JumbosIt is common practice to bump up the drive end of drifting drill steel for added strength at the rock drill end to accommodate larger diameter shank adapters. Bloom's heavy-duty drill steel is available in many standard lengths to match the drill feeds on a multitude of available drifting jumbos. Since the coupling does not enter the hole, a bit diameter closer to the steel diameter can be used. Thissignificantly enhances flushing and hole accuracy.

Specifications & Availability

• Thread Combinations: Standard T38 bit end threads with heavy-duty shank end thread types.

• Body Profiles: Available on high-stiffness 32mm Hexagon (Hex 32 / R32) body with a reinforced 35mm heavy-duty drive end (F-Hex35).

• Standard Lengths: 2440mm to 6435mm (8'- 21') to suit all major drifting jumbo feeds.

  
  

Why Choose Hexagon Drifting Drill Rods (Hex 32)?

• Superior Rigidity: The cross-sectional dimension of material is measured across the flat. Cross sections are more rigid, heavier, and transfer impact energy far more efficiently.

• Enhanced Hole Flushing: Reduces the annulus in the drill hole for better flushing performance. The smaller clearance combined with the corners of the hexagonal steel creates high-velocity turbulence in the hole.

• Perfect for Horizontal Drilling: This turbulence keeps the heavier rock cuttings constantly moving, preventing jamming, especially in horizontal tunneling and drifting holes.

• High Torque Resistance: The rigidity of the Hex 32 cross section makes it highly stable when utilizing larger threads like T38, preventing unexpected snapping or thread fatigue.
