Cutting
High-concentration diamond abrasive delivers extremely fast cutting speed and removes metal approximately 10–15% faster than comparable CBN stones.
Binder
The vitrified-metal binder provides aggressive performance, stable geometry, flatness retention, and long operational life.
Application
PDT Premium Silver Diamond stones are designed for users who prioritize sharpening speed, efficiency, and high throughput.
Diamond vs. CBN
Diamond stones provide faster and more aggressive metal removal, making them the preferred option for maximum productivity.
CBN stones typically produce a cleaner scratch pattern and smoother finishing feel during edge refinement.
The Silver Diamond series also offers a strong performance-to-value balance for demanding sharpening work.
