Komatsu blasthole drill steel — both fabricated and integral — is tailored to your specific drill regardless of manufacture, OD diameters of 7" to 13 3/4". Our fabricated drill steel features tool joints made from alloy steel and is inspected with ultrasonic technology for quality assurance. Wrench slots or flats are milled to suit the requirements of the drill's wrench size and location. All rotary-shouldered connections are kemplated to protect against galling during the break-in period. Heavy wall construction and optional hard facing help promote longer life and lower operating costs.
