Mining of hard rock :
The mining of hard rock typically requires the drilling of both exploratory and blasting holes, and we can offer inserts to mount into drill tools or the finished drill tools. The choice of tooling options is designed to suit the differing needs of mines across the world and we work with mining tool equipment manufacturers to match lab grown diamond and carbide performance characteristics to their specific needs.
Mining of soft rock :
We also developed a range of hard wearing tungsten carbide products and is currently developing a lab grown diamond pick which we believe will offer overwhelming benefits to the industry.
We offer a full range of round shank picks with a full range of head designs, retainer systems and inserts available to specific requirements. Customised tools can be manufactured upon request.
Drill bits are available for blast hole drilling and roof bolting and are equipped with tungsten carbide or polycrystalline diamond inserts to suit the rock conditions.
Our lab grown diamond grits and powders solutions :
Leo da vinci group is able to fully utilise lab grown diamond as the working face material in exploratory and blast hole drilling through the world’s hardest formations. In lab grown diamond grits,our group offers a range of sizes, strengths, coatings and encapsulation technologies to serve a wide range of hard rock drilling needs.
Polycrystalline diamond (PCD) :
We offer polycrystalline diamond (PCD) for use on large cutting or percussive/impact surfaces that can be mounted on drill heads and picks to increase penetration rates and offer longevity of performance life – a valuable feature in geographically remote operations. Where properly applied, PCD tools provide the end-user with unsurpassed levels of productivity and workpiece quality.
Our lab grown diamond-enhanced hard rock inserts represent an integration of advanced material design and product engineering to produce a cost effective solution for performance-focused drilling. The dimensions of our lab grown diamond-enhanced hard rock inserts are produced to customer specifications.
