Metal Hole Cutting Tools and Multi-Purpose Hole Saws

• The High Speed Steel (HSS) allows the bit to cut faster than High Carbon Steel. At room temperature, HSS and high carbon steel have an equivalent hardness; at elevated temperatures, HSS become advantageous.
  
  
• The Titanium Nitride (TiN) coating is an extremely hard ceramic. It is often used as a coating on HSS to improve hardness and durability.
  
  
• Cobalt alloy bits are the best choice for cutting stainless steels.
