Abstract
Inventia se refera la un cutit tubular format dintr-un corp în forma de cupa interioara avînd la capatul deschis dinti taietori frontali între care sunt practicate caneluri ce se desfasoara elicoidal de la planul frontal exterior spre capatul opus lacare fiecare dinte este legat de dintele alaturat cu o nervura sau inima de material desfasurata elicoidal a carui perete exterior formeaza fata interioara a canelurii de evacuare corespondente. Fiecare canelura de evacuare are deasemenea un peretel ateral radial, dintii aschietori frontali sunt prevazuti cu cîte o muchie aschietoare radiala interioara coborata cu o muchie aschietoare exterioara intermediara. Dispunerea acestor muschii asigura desprinderea de fiecare dinte a unei aschii distincte niste muchii aschietoare interioare si niste muchii aschietoare intermediare sunt practicate pe o nervura sau inima de material prevazuta cu niste canale desfasurate de la baza spre coada frezei pe muchiile aschietoare corespondente deschise sau evazate radial spre exterior în nelurile de evacuare corespondente astfel încît la terminatiile superioare muchiile aschietoare intermediare avînd o desfasurare radiala mai mica decît grosimea inimii de material fiecare canelura de evacuare avînd adîncimea sau dimensiunea radiala mai mica decît dimensiunea radiala a muchiilor aschietoare interioara si intermediara.
