StraightLine® Backreamers  

Maxi Barrel Reamer

The barrel reamer has a relatively flat face lined with rows of carbide cutters that allow the tool to cut and open the hole slightly larger than the diameter of its solid body. The reamer's cutting teeth overcut the tool body, allowing the slurry to flow past the reamer.

The barrel reamer is a very versatile tool:

  • Commonly used in bores where the formation types are relatively soft.

  • Used as a stabilizer when pulling larger reamers, fly cutters or hole openers.

  • Regularly used when installing the final product.

Shaft size: 4 1/4” – 10 5/8”
Size range: 20” – 84”
