high performance 127 mm M40 DTH rock drill button bits for DTH drill rig
Sanlytols has a comprehensive range of DTH drill bits to match all conceivable applications.
Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the requrired hardness, given surfacure compression for fatigue resistence , and fitted with precision buttons manufactured in-house.
Four basic designs are available: Convex, Flat front, SpeedBit, and Concave Bit. These are designed for specific application for all rock types, hardness's and conditions.
Bit life and rate of penteration are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the fast cuttings removal features of the SpeedBit and Convex/Ballistic desgins are preferable, to ensure the buttons are cutting clean, with the minimum of recrushing.
In hard and abrasive formations, however, the flat front design offers best bit life, having strong gauge rows with large speherical buttons which are easy to regrind and maintain. The SpeedBit offers improved productivity with the same gauge as the flat front, but with ballistic buttons in the front for faster penetration. An alternative is the concave design with spherical buttons.
Bits are manufactured to match all diameters of Sanlytols hammers .
