Design & Manufacturing

HMI’s software and CNC Machining facilities enable the design, engineer and manufacture of custom parts and prototypes for clients based on their specific requirements. HMI designs 3D models of tooling systems and machines using lathes and milling machines with 4 and 5 axis functionality. HMI is the only place to go for made-to-order, custom designed, and specialised tooling.


Repair & Refurbishment

HMI offers a full refurbishment facility for building and repairing all PDC products using various brazing techniques and Premium Syndrill™ cutters in repair work. Your ground engaging tools can be strengthened through wear protection which HMI can complete at their workshop or on your work site. All work is carried out in accordance with our quality control systems to ensure superior finished products.



From modifying existing tools, creating new tools or developing and fabricating devices to make tasks more efficient – HMI’s fabrication facility uses a range of welding techniques to create the tools and support devices you need to get the job done.


Tungsten Carbide Recycling

HMI offers cash back on scrap tricones, PDC bits and any products that contain tungsten carbide. We source materials containing tungsten globally and process these in our facilities in South Africa, turning this scrap into tungsten granules and powders.
