Cobalt-free precision diamond tools.
PIB™-bonded diamond tools engineered for cutting, grinding and drilling in stone, concrete and ceramics — without cobalt or carcinogenic compounds.
What It Is
High-performance tools. Cobalt-free chemistry.
Diamond tools work by embedding industrial diamond crystals in a sintered metal matrix. In conventional tools, cobalt acts as the primary binder — but cobalt is a classified probable carcinogen, a volatile commodity, and an increasing regulatory concern.
Every Bagwell diamond tool runs on PIB™ — our Pure Iron-Based bond system developed through advanced powder metallurgy research. It delivers the same controlled wear behaviour and bonding strength as cobalt, without any of the health or supply chain risks.
Why It Matters
The case for cobalt-free diamond tools.
Cobalt dust is classified by IARC as a probable carcinogen. Removing it from the bond matrix reduces exposure risk on every cutting and grinding operation.
No cobalt means no heavy metal contamination in slurry, waste water or site runoff — cleaner production and cleaner job sites.
Cobalt pricing is driven by EV battery demand and high mining concentration risk. PIB™ removes that supply chain dependency entirely.
Occupational exposure limits for cobalt are tightening across the EU and UK. PIB™ tools are already aligned with where regulations are heading.
