Carbide Test for Magnum Cutter in Kiruna

Atlas Copco Secoroc tested a new carbide grade at Kiruna Mine in the North of Sweden with Bergteamet Raiseboring Group. The harder tougher grade of carbide was used on standard Magnum V cutters. The cutters were then put on a 3.1 meter (in diameter) integral reamer. This reamer employs 5 gage cutters, 3 next to gage cutters with 2 cutters on each of the remaining rows throughout to the center of the head. The total number of cutters on the reamer was 18 (eighteen).
Epiroc operated under the trademark “Atlas Copco” prior to January 1, 2018.
