Blasthole Drill Steel

Joy blasthole drill steel, both fabricated and integral, is tailored to the particular drill. Our fabricated drill steel features tool joints made from alloy steel and is inspected by ultrasonic means as part of our quality processes. Wrench slots or flats are milled to suit the requirements of the drill. All rotary-shouldered connections are kemplated to protect against galling during the break-in period. Heavy wall construction and optional hard facing result in longer life and lower operating costs.

Our integral drill steel is made from premium quality alloy steel bars. Bores are trepanned to sizes that result in the correct balance for the selected rotary-shouldered connection. Integral drill steel is available step-bored to reduce weight while concentricity and axial alignment of the connections to the drill steel are held to close tolerance. Application of tungsten hard facing is available to protect both fabricated and integral steel from abrasion and erosion.
