Drill Matrix
Attributes
Material hardness and machinability affect speed, feed, and cut depths.
For dimensional and finish quality, a low TIR of the tool-holder assembly in the machine is critical: less than 0.1% drill diameter is preferred.
Spot drilling is not necessary in most situations if the drilling surface is machined flat ; spot drill point angle should be greater than drill point angle.
Liquid coolant (internal or external) such as oil based or synthetic is highly recommended for all drilling applications.
For proper cooling, lubrication and chip evacuation, ensure the coolant is supplied throughout the entire depth of the hole.
When liquid coolant cannot be applied for applications such as plastics or composites, clear the swarf with air or vacuum.
Depending on material machinability, a peck cycle may be neccesary for external coolant drills beyond 2x or 3x depths.
