Engineering & Fabrication Services
Beyond our own drilling rigs, the Drillbuilders workshop in Mokopane takes on cutting, machining, welding, fabrication and hydraulic work for outside customers. Send us a drawing — or a photo of a sketch or a worn part — and we build it.
Hydraulic cylinders — designed and built in-house
We design and build every hydraulic cylinder that goes into our drilling rigs, from the bore to the hard-chrome shaft. We can build cylinders to your duty and mounting requirements too.
- Bores built to date: 80, 90, 100 and 125 mm
- Strokes up to 6.35 m
- Working pressures 175–250 bar
- Every shaft hard-chrome plated
Laser & profile cutting
Send us a DXF, a drawing or even a sketch and we cut your parts, hole patterns and nested profiles ready for fabrication — on a full 4 m by 2 m fibre-laser bed.
- Full 4,000 x 2,000 mm sheets cut in a single setup
- Fine, accurate edges — to within 0.05 mm
- Hand plasma cutting for on-site and heavy manual work
The rest of the workshop
Welding & heavy fabrication
Heavy structural steel fabrication by qualified boilermakers — chassis, frames, tanks, brackets and more.
- Multiple heavy welding bays (MIG/MAG up to 500 A)
- 3D fixturing tables for square, repeatable weldments
- Our own 100 kVA generator — loadshedding doesn’t hold up your job
- On-site handling: forklifts to 4 t and a 30-ton excavator
Machining: turning, milling & drilling
A full machine shop for shafts, bushes, adaptors, flanges and keyways — one-offs, repairs or batches.
- Turning up to 560 mm diameter swing, 2 m between centres
- Milling, drilling and keyway cutting
- Reverse-engineering from a sample or worn part
Plate & sheet shearing
Clean guillotine cuts across a full 3.2 m plate width in a single stroke.
- Mild steel up to 8 mm, 3.2 m cut length
- Standard sheets sheared without pre-cutting
- Powered backgauge for repeat batches
Steel prep: punching & cropping
Hole punching, bar shearing and angle cropping on a 90-ton ironworker — weld-ready steel, fast.
Section & bar sawing
Accurate cut-to-length sawing of heavy bar, pipe and structural sections.
- Bar and section cutting to around 270 mm
- Mitre cuts to 45 degrees
Plate rolling & pipe bending
Plate rolled into cylinders, cones and drums; hydraulic pipe and tube bending for frames, guarding and hydraulic lines.
Hydraulic pressing & straightening
100-ton hydraulic pressing for bearings, bushes and pins — and cold-straightening of bent shafts and sections.
Hydraulic hose assemblies
High-pressure hydraulic hose assemblies cut, skived and crimped in-house while you wait.
From your sketch to a finished part
Bring us a drawing, a sample, a photo or a WhatsApp snap. Our in-house engineer and draughtsman turn it into manufacturing-ready CAD (SolidWorks and Onshape) before a single part is cut — design, detail and build under one roof.
