Rock Drill Manufacturer Closes-Pit Carburizing Furnaces Going to Local Heat Treater

“Boart Longyear” a global manufacturer supplying rock drills around the world, for many years maintained a location in Mississauga, Ontario, Canada which went under the name “Boart Longyear Drilling Products Canada Ltd”. Earlier this year it was announced this facility would be closing with production moving to China. All of the equipment including the heat treat department went to auction this past summer and was removed by the end of August.

The heat treat department consisted of a gas fired pit carburizing furnace with working dimensions of 21’ deep X 7’ diameter, two pit temper units and an Endothermic generator-everything provided by “Surface Combustion” many years ago. Also included was a “Tocco” Induction hardening system.

Reliable rumors say that the pit carburizing furnace was acquired by a local commercial heat treater with installation planned for spring of 2027.

Pit carburizing furnaces this large, in particular the working depth of 21’ are relatively uncommon in North America and unheard of in Canada. As a matter of fact they are so rare that “The Monty Heat Treat News” had an article earlier this year about this exact topic; “Is There a Shortage of Large Pit Carburizing Capacity in North America”?

We will update you on this story as more details become available.
