Tool Repairs & Rebuilds

Don’t replace ituntil we’ve seen it

Reamers, PDC bits and rockmotors wear out — but a worn tool isn’t automatically a written-off tool. We assess it, tell you what’s worth doing, and rebuild it in our workshop.

You keep using a tool you’ve already paid for, instead of buying it twice.

The Same Tool

Worn Out. Then Back to Work.

A rock reamer that came in with worn teeth and a rusted body — re-toothed, hard-faced and returned ready to run.

How It Works

Three Steps, No Guesswork

01

Get in Touch

Tell us what the tool is and what’s happened to it. We’ll ask you to send photos through so we can see the wear before it travels anywhere.

02

We Assess and Quote

Every tool is different. We look at the body, the cutting structure and the connection, then tell you what’s worth doing — and what isn’t.

03

Rebuilt and Returned

Cutters and teeth supplied and fitted, hard-facing laid, bodies repaired. The tool comes back to you ready to run.

What We Rebuild

Reamers. PDC Bits. Rockmotors.

Three of the most expensive things in your tooling inventory — and three of the most commonly replaced when they didn’t need to be.

Reamer Refurbish & Rebuild

Compaction, fluted, paddle, turbo and rock reamers — assessed tool by tool.

✓Worn and broken teeth replaced
✓Hard-facing laid on wear surfaces
✓Damaged bodies repaired
✓Connections and tow eyes checked

PDC Bit Refurbish & Rebuild

Bits and PDC reamers brought back into service rather than scrapped.

✓Missing and damaged PDC cutters supplied and fitted
✓Blade and body repair
✓Hard-facing where it’s worn away
✓Nozzles and inserts replaced

Rockmotor Service & Rebuild

AT-Boretec rockmotor housings serviced in our workshop, or kits supplied so you can do it on site.

✓Full in-house strip and rebuild
✓Service kits with all bearings, bushes and seals
✓Inner shafts, bit boxes and sonde lids supplied
✓Returned ready to drill

Not Just These Three

If It’s HDD Tooling, Ask Us

Those are the three we’re asked for most often, but they’re not the limit. If a tool is worn, damaged, or sitting in the yard waiting to be written off, send it to us before you replace it.

And If It’s Not Worth It, We’ll Say So

Some tools are past saving. If the body’s gone or the economics don’t stack up, we’ll tell you that instead of taking the job — and we’ll help you spec the replacement properly. Straight answer either way.

Before You Replace It

Get Your Tool Assessed

Tell us what you’ve got and what’s happened to it. We’ll let you know whether it can be rebuilt, what’s involved, and whether it’s the right call.
