Vitricarb Grinding Mandrels
For those who prefer the added rigidity of solid carbide and a finer finish
- These mandrels are fully impregnated
- They are designed for smoother finish and longer life
- The bonded heads have been sintered directly to carbide shanks for extra rigidity if excessive pressure is needed
Standard Grits
| VBB | VBD |
|---|---|
| 150 thru 154-180 grit | 50 thru 51-220 grit |
| 155 thru 173-150 grit | 52 thru 52-180 grit |
| 174 thru 187-100 grit | 65 thru 73-150 grit |
| 74 thru 87-100 grit |
OUTSTANDING FEATURES
- Carbide mandrel for greater rigidity
- Faster cutting and safer operation
- Longer and truer holes are ground
- Fuses directly to the carbide mandrel
- Does not load up if properly used
- May be used with or without coolant
- Withstands considerable abuse
FULL DEPTH CRYSTAL SECTION
Since the bond holding the crystals fuses to the carbide mandrel eliminating any cement layer torque condition, the crystal section may be full depth… with the depth determined by the wheel size and the diameter of the carbide mandrel. This contributes effectively to the maximum economy and long service of Vitricarb wheels.
On wheels using mandrels 3/16″ and 1/4″
On smaller wheels the mandrel diameter at the the wheel-mounting area is wheel is generally smaller than the diameter, serrated to provide greater bonding/fusing diameter of the chucking section. This is area and maximum strength, particularly advantageous because the mandrel area behind the wheel may be ground down and the wheel used for other applications.
