Technical Information for Vulcan Drill
G
High feed and precision machining with our specially designed point edge
Vulcan Drill
High feed and precision machining due to specially designed point edge
Vulcan drills ensure longer tool life under high speed condition because of increased
thermal & wear resistance. It also uses a PVD coating with an exclusive substrate to help
maintain reduced frictional resistance
Low cutting resistance by the best design of clearance angle is possible to increase feed
Smoother chip control due to improved chip breakage
Rmax: 6~25s, Hole tolerance: IT8 ~ 10
Strong shock resistance ensures long tool life under the heavy interrupted machining

The factors below
determines the
straightness of hole.
• Drill diameter and depth
of drilling
• Cutting condition and
kind of application
• Kind of workpiece and
machine
• Drill bush
Required machine power
Straightness
Quantity of coolant
Pressure of coolant
Solid drill
The above graph shows general information and it is changeable depending on kind of tool,
workpieces, and cutting conditions etc.
• Pressure and quantity of coolant - High pressure of coolant ensures excellent chip evacuation and cooling the cutting edge.
• Use a filter for removing impurities - The diameter of a filter should be less than 20. Impurities could make bad flow of
coolant, wear on a tool, and high load on the cooling pump.
• Temperature of coolant - Proper temperature of coolant : 20°C~ 22°C / Do not use coolant at 50℃ above
