How to select the correct taper shank drill bit for a machine?

To select the correct taper shank drill bit, match the shank size (e.g., MT4) to your machine spindle's Morse taper socket. Ensure the diameter (38 mm) suits your hole size and the material (HSS with black oxide) is appropriate for the workpiece. Always verify the point angle (118°) for general-purpose drilling.
