HAL Heavy Duty Machining Australia
Welcome to our heavy duty machine shop. We specialise in the drilling industry and are located in Central Qld, Australia.
My name is Matt, and in a nutshell we make super heavy duty gear that drillers typically love breaking.
Hydraulic cylinders, drilling crossover subs, drill bits, recovery gear... the list goes on. If it's drilling related, we do it.
WHY HAL?
We chose to name the channel after my late grandad Hal.
After working on a drill rig since the age of 14, Grandad then "retired" from drilling at age 60 to "the machine shop" ... and then proceeded to work until his 87th birthday.
THE CHANNEL
This little channel is just about sharing some of the weird and wonderful gear we get to make in the machine shop... and how drillers manage to break it.
I upload once a fortnight (or weekly if possible...) and really appreciate all the comments from around the world. You guys are awesome. Thank you.
