Factory Supply Unground Tungsten Carbide Valve Ball And Seat
Usage
1. Used for coarse abrasion on gold and other precious metals,
leaving a smooth surface on acrylics.
This reduces rework.
2. Shaping fissure on a variety of materials. Used on gold,
composite veneers or ceramics prior to final firing, they always
display convincing cutting proper and an impressively long service
life.
3. Engraving bits, carving bits.
queen-quality tungsten carbide valve ball for valve seat cutting
machine
Feature
1. Made by 100% original tungsten carbide materials
