We specialize in supplying Tungsten Carbide inserts and brazing those inserts directly into customer-supplied bodies. You bring the steel parts, we do the rest. Working with WC inserts varying in size from 1/8" to 1/2" diameter, we deliver tight, reliable braze joints at a scale and precision that is hard to find. Every single assembly is inspected. If you supply GO and NO-GO Gauges, we ensure the inserts pass your standards. No guessing, no sampling, 100% verification. If it doesn't pass, it doesn't leave. This is the kind of work that demands consistency. Small diameters, hard materials, customer-supplied components. There is no room for error when the part isn't yours to remake. We hold the tolerances and we hand it back ready to use. If you've got components that need carbide brazed in with confidence, Hand In Hand Technologies are your specialists.
