General Drilling Guidelines
WARNING: To avoid injury, make sure the chuck key is removed from the chuck before
starting any drilling operation.
Drilling speeds
Important factors when determining the best drilling speed:
Type of material
Size of the hole to be drilled
Type of drill bit or cutter
Desired quality of the cut
Remember, smaller drill bits require greater speed than large drill bits. Softer materials require
greater speed than harder materials.
