Automatic Feed Adjustment: Smooth boring welding machine operation for precise metal machining
360-degree Machining Capability: Portable line boring machine handles multi-position repair work
Product Introduction
When heavy equipment pin holes wear out, crack, or become out of round, traditional repair methods—like disassembling the entire component and transporting it to a workshop—cost time, money, and lead to costly downtime. Our Portable Boring and Welding Machine for Pin Hole Repair solves this pain point by integrating two critical functions: high-precision boring and reliable welding, all in a compact, portable design that works on-site, no matter how tight or remote the location. Engineered specifically for repairing worn or damaged pin holes on construction machinery, agricultural equipment, marine vessels, and industrial machinery, this all-in-one machine eliminates the need for separate boring and welding tools, streamlining your repair process and getting your equipment back in operation faster.

Product Details.
1. It actually fits in tight spaces
Most "portable" boring machines are huge. They won't fit between the boom and arm of an excavator. Which defeats the whole purpose of being portable.Ours is small enough to fit anywhere. I've had guys use it to repair pin holes on 50 ton excavators without taking a single bolt off. That's the whole point.
2. Stupid simple controls
We designed the control panel for mechanics, not engineers. There are 3 knobs. One for spindle speed. One for feed rate. One for welding current. That's it. No touch screens. No complicated menus. Nothing to break.If you can operate a welder, you can operate this machine.
Product Usage Scenarios
This boring and welding machine fixes pin holes. That's it. That's all it does. But it does it better than anything else on the market.Here's what our customers use it for every day:
Excavator boom, arm and bucket pins (this is 80% of the repairs)
Loader bucket and lift arm pins
Bulldozer blade pins
Crane outrigger pins
Dump truck bed hinges
Tractor loader pins
Forklift mast pins
Any other pin hole on any heavy machine
If it has a pin that goes through a hole, this machine can fix it.
I've had guys use it to repair pin holes on ships.
Customer Feedback
These are actual messages from our customers. I copied and pasted them directly. I didn't change a single word.
"I bought this bore repair welding and boring machine last March. I had just got a quote for $7,200 to fix a pin hole on my Cat 320. The shop wanted 10 days. I fixed it myself in 2 hours and 45 minutes. I've done 13 repairs since then. This thing has already made me over $40,000. Best money I ever spent. The only thing I would say is the instruction manual is a bit shit, but the video is good, and when I called they walked me through everything."

"We're a mining company in Western Australia. We're 800km from the nearest town. If a machine breaks down, we lose $25,000 a day. We bought two of these machines two years ago. They've paid for themselves 10 times over. They work in 45 degree heat and dust storms. We've never had a single problem. When we needed extra boring bars, they shipped them DHL and we had them in 3 days."
— David Thompson, Australia
"I've been a mechanic for 22 years. I've used every brand of portable boring machine there is. This is the best one by far. The one spindle design is a game changer. I used to spend an hour aligning my old machine. Now I don't. I can do two repairs a day easily. The build quality is excellent. I've had mine for 3 years and it's still like new."
