When deciding on which bur to buy or to use, be sure to take into account the material of each bur and its use with precious metal counterparts
• HIGH CARBON:
More precise cutting, can be used effectively at slow speeds, better strength and hardness with tungsten & vanadium added
Can be used with: gold, silver, platinum, copper, bronze
• HIGH SPEED STEEL:
(HSS) Heat resistant, tougher than carbide, less chatter
Can be used with: gold, silver, copper, brass, aluminum, pewter
• CARBIDE:
Heat and wear resistant, maintains sharp edge, works best at medium to high speeds
Can be used with: gold, silver, platinum, copper, brass, bronze, titanium, steel, stainless steel
• DIAMOND:
Good for grinding, carving, and sculpting; shorter lifespan than carbide burs
Can be used with: stone, glass, precious and non-precious metals
