Broca de rosca.
Estime o diâmetro da broca pelo diâmetro nominal, pelo passo e pela porcentagem de rosca.
Drill = major − pitch × (percent / 75). At 75% this matches the common one-pitch chart rule. It is a shop estimate, not a gauge inspection. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.

Drill diameter = major diameter − pitch × (thread percent / 75). At 75% this is the common chart rule of one pitch under the major diameter. It is a shop estimate, not a thread-gauge inspection.
