For external coolant supply
With a vertical processing machine, there is no step up to 3D hole depth. If you exceed 3D, you can use 1D~2D steps as a guide. (D: Drill diameter)
If you
Drill selection procedure How to choose the right drill
Step (1) Check how many times the depth of the hole to be processed is the diameter
If the drill diameter (D) is 10 mm and the depth is 30 mm
Calculate 30÷10=3 and consider it "3D"
Step (2) Find a drill that is compatible with the workpiece material
(FAQID:692)
Estimating thrust, torque, and power requirements
When considering the clamping method and clamping fixture of the workpiece, the thrust and torque generated during drilling must be considered. If you want to make an approximate guess, you can find it from a simple empirical formula. Here
A general-purpose drill that is carbide and can be used in external coolant supply instead of internal coolant supply is
If the machining environment (workpiece shape, machine, etc.) is sufficiently rigid, consider counterboring machining from a state where there is no Pilot hole . This is because chips are easier to separate and better processed without Pilot hole .
If there is a Pilot hole
