What is Blast Hole Drill Bits?
IADC 6 SERIES DRILL BITS
The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Medium to Medium-Hard Formation
Application: For use in moderately abrasive consolidated formations with compressive strength ranging between 140 – 485 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic formations
Cutting structure: These bits are characterized by moderately spaced conical inserts with medium projection. This configuration promotes good penetration rates in medium hard and moderately abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.
In the mining industrial, blast hole drilling is very important to achieving the required product or outcome. Drilling suitable holes allowing explosive charges to be placed down the holes. And then to blast large areas making them more manageable and easier to remove.
Bits thread are manufactured according to API standards.
