Diamond & CBN Stones

Diamond and cubic boron nitride (borazon, cubonite, elbor) sharpening and honing stones. If you do not know which stone to select - review Recommended sets of sharpening stones.  

Diamond sharpening stones have high productivity and may be used for wide range of materials: carbide, cast iron, HSS, ceramics.   
Cubic boron nitride sharpening stones are  designed for high quality processing of steels.  
 
Metal bond stones:
flat solid block (copper-tin alloy), abrasive grains are distributed evenly across the stone. Metal bond stone does not need support plate, and offers high productivity on rough surfaces, as well as long tool's life. 
Resin bond stones: flat solid block (phenol formaldehyde resin), attached to support plate (aluminum blank). Resin bond stones offer high quality of polishing and usually do not clog. 
Combined bond stones: our innovative solution, which combines best qualities of resin and metal bonds: high performance, mirror polishing and long tool life.

Bond: combined bonds to ensure the best performance.
Grain sizes: 1/0- 63/50 - resin bond BP50  for polishing
Grain sizes 80/63 - 160/125 - wear resistant metal-resin bond BP08 for grinding
Grain sizes 200/160 - 500/400 - metal-resin bond BP05 for roughing

Grain size: Please select from the list, or read Technical information.  
The finest grain size is 0.5/0 micron (fine polishing) , the coarsest - 200/160 micron (rough grinding). 
In grain selection window you see grain sizes according to standards:
MICRON=MESH(GRIT)=FEPA

Diamond concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.

Flat solid block on aluminum blank.

Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers, unless stones are prepared before shipment.
So there's "Stone preparation" option in dimesions selection window.

Use and cleaning of  sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones -  with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.   
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.

You may buy 100 gr. of FeCl in dimensions selection window (click also any grain size to select it). I sell it if you buy a stone.

CBN SHARPENING STONES, COMBINED BOND (CBNST)
CUBIC BORON NITRIDE HONING, SHARPENING STONES
150 х 25 х 7 x 3 x 4

CBN (cubic boron nitride)
 is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite, etc. 
CBN (cubic boron nitride) is the second-hardest material after diamond,  and has the best price-performance ratio for processing steels, comparing to other materials, including diamond, silicon carbide or aluminum oxide.  
Due to it's high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.  

Length: 150 mm = 6 inch
Width:   25 mm x = 1 inch
Total thickness:  7 mm = 0.28 inch

RECOMMENDED SETS OF SHARPENING STONES (150-25-5-2)
RECOMMENDED SETS OF DIAMOND AND CBN STONES, METALL AND RESIN BONDS
 
Recommended selections of sharpening stones to make your choice easier:
- Highlight your operations: do you have "forming cutting edge" operation ?  What surface quality do you need, just "nice at eyesight" (polishing) or mirror (the finest polishing). So skip sets with unnecessary grains. 
- What is your workload ? If from time to time - skip metal bond stones, they are more expensive, but lasts longer. 
- The more knives you sharpen, the more you need stones, to keep steps in working operations (distances between grain sizes) shorter.

Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers, unless stones are prepared before shipment.
So there's "Stone preparation" option in grain selection window.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 year), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
   - 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),
   - 10 mins polish movements (carefully draw "8") on glass plate.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.

150-25-5-2  AND  150-25-7-3 

 
CBN (cubic boron nitride) is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite, etc. 

CBN (cubic boron nitride) is the second-hardest material after diamond,  and has the best price-performance ratio for processing steels, comparing to other materials, including diamond, silicon carbide or aluminum oxide.  
Due to it's high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones.  


Length: 150 mm = 6 inch
Width:   25 mm = 1 inch
CBN height: 2 mm = 0.08 inch / 3 mm = 0.12 inch 
Total height (with blank): 5 mm = 0.2 inch / 7 mm = 0.28 inch

Bonds:
150-25-5-2 -
Edge-resistant resin bond BN-130 does not require coolant.
150-25-7-3 - Copper-resin bond BP50, it is as wear-resistant as copper-tin (metal) bond, but softer, does not require coolant. 

Grain size: Please select from the list, or read Technical information.  
The finest grain size is 0.5/0 micron (fine polishing) , the coarsest - 200/160 micron (rough grinding). 
In grain selection window you see grain sizes according to standards:
MICRON = MESH(GRIT) = FEPA

Grain concentration: 200%
Do not waste your money on cheaper stones with lower/unknown concentration.
 
Flat solid block on aluminum blank.
 
Available on stock 

Application
For knife sharpening using such sharpeners as Hapstone, Edge Pro, Kazak Pro.

Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers, unless stones are prepared before shipment.
So there's "Stone preparation" option in grain selection window.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 year), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.
