CBN Sharpening Stones – High-Performance Precision for Hard Steels

CBN (Cubic Boron Nitride) sharpening stones are the ultimate solution for sharpening high-hardness steels (60+ HRC). Designed for superior durability and cutting efficiency, these stones outperform traditional abrasives, ensuring fast and precise sharpening results.

At USA-Market.net, we offer premium CBN sharpening stones from top manufacturers like PDTools (Poltava Diamond Tools) and KDTU (Kyoto Diamond Tool Ukraine). Unlike electroplated alternatives, our stones feature sintered or bonded CBN layers, providing a significantly longer lifespan and consistent performance.

Why Choose CBN Sharpening Stones?

CBN is the second hardest material after diamond but is thermally stable and does not react with iron-based alloys. This makes it the best choice for sharpening high-hardness steel knives.

Key Benefits of CBN Stones:

✔ Superior Hardness – Easily sharpens steels over 60 HRC with minimal wear.
✔ Fast & Efficient Sharpening – Removes material quickly, reducing sharpening time.
✔ Extended Lifespan – Sintered and bonded CBN stones last much longer than electroplated alternatives.
✔ Consistent Performance – Delivers uniform sharpening without losing efficiency over time.
✔ Ideal for High-Performance Steels – Perfect for sharpening tool steels, high-carbon steels, and premium stainless steels.

Choosing the Right Grit for Your Sharpening Needs

CBN stones come in a variety of grit sizes, allowing users to select the perfect option for their application:

🔹 Coarse Grit (#60–#240) – Ideal for reshaping dull or damaged edges.
🔹 Medium Grit (#285–#650) – Perfect for refining edges after initial sharpening.
🔹 Fine Grit (#1100–#1500) – Produces razor-sharp edges suitable for professional use.
🔹 Ultra-Fine Grit (#5000–#15,000) – Achieves a mirror-polished, hair-splitting sharpness.

CBN Bonding Types – Which One to Choose?

The bonding type of a CBN stone affects its cutting speed, durability, and sharpening quality:

🟢 Resin Bond – Best for finishing and polishing, works well with light water-based lubrication.
🔵 Hybrid Bond – Balances speed and precision, ideal for fine sharpening.
🟠 Metal Bond – Extremely durable, excellent for aggressive sharpening of hard steels.
