Conforme a norma DIN 345 \/ DIN 8035, as medidas das brocas com haste c\u00f4nica s\u00e3o definidas por:<\/p>\n

    \n
  1. Di\u00e2metro nominal (d1) \u2192 vai de 6 mm at\u00e9 80 mm.<\/li>\n
  2. Comprimento total (L) \u2192 aumenta conforme o di\u00e2metro.<\/li>\n
  3. Comprimento da parte \u00fatil (l2) \u2192 comprimento da h\u00e9lice (zona de corte).<\/li>\n
  4. Cone Morse da haste (CM) \u2192 varia de CM1 a CM6, dependendo do di\u00e2metro da broca.<\/li>\n<\/ol>\n
