5 Benefits of the Bora7 Sanding Belts for Knife Makers
Creating Truly Exceptional Blades
When it comes to high-end knife making, abrasive choice often becomes a differentiator between a merely serviceable finish and a truly exceptional blade. For knife makers working with stainless steels, high alloys, or demanding geometries, the Bora7 purple ceramic 2″ × 72″ sanding belts from Preferred Abrasives deliver cutting power and durability that many conventional belts can’t match.
What Is the Bora7 & Why It Matters
Preferred Abrasives offers Bora7 2″x72″ sanding belts, featuring a new purple ceramic grain designed for alloyed and stainless steels, with maximum material removal in mind. The design is a stiff ceramic (CA/Y Plus) developed to fracture with high pressure, continually exposing fresh cutting edges, a key feature that keeps performance consistent across the belt’s life.
Compared to other ceramic abrasives, the Bora7 offers a balance of aggressiveness and thermal stability. It can be used either wet or dry, and includes a supersized coating with an active filler to help reduce heat and scorching during use. This sanding belt is ideal for high-speed grinding on materials where heat buildup can damage the metallurgy of the steel.
The Bora7 is available in 2”×72” belt grinders, ideal for knifemakers, fitting seamlessly into most shop setups.
5 Benefits of Bora7 Sanding Belts for Knife Makers
1. High Material Removal & Efficiency
When profiling blades, removing stock, or grinding tapers, efficiency is paramount. The Bora7’s aggressive cutting action allows more metal removal per pass, optimizing the production process.
2. Longer Belt Life & Consistency
Because the ceramic grain renews itself by fracturing under load, the belt maintains consistent cutting performance rather than dulling uniformly. This also means you get more usability and lifetime out of it before needing to replace it.
3. Heat & Burn Resistance
The Bora7’s active filler and tough ceramic grain mitigate burning during the grinding process. This is a key benefit for knife makers when working with stainless steels or sensitive alloys. This gives knife makers more freedom in feed rate and pressure without worrying that the belt will overheat or damage the material appearance of the knife blade.
4. Versatility (Dry or Wet)
Bora7 belts can be used either dry or wet, giving flexibility in how knife makers choose to approach grinding, depending on blade material, cooling strategy, or finish goals.
5. Wide Range of Grain Sizes
One of the key benefits of these sanding belts is the broad grit range available in the Bora7 purple ceramic. Available from 36 to 120 grit, this gives knife makers the flexibility to adopt Bora7 belts for both coarse stock removal and mid-range smoothing before moving into finer finishes.
Bora7 Purple Ceramic 2″ × 72″
For knife makers seeking a high-performance, durable, and versatile abrasive belt solution, the Bora7 purple ceramic 2″ × 72″ sanding belts from Preferred Abrasives are an ideal choice. Their ability to handle alloyed and stainless steels aggressively, ability to resist burning, range of grit sizes, and ability to maintain consistent performance over time are key factors for knife makers to consider.
