Title (EN) ANNULAR HOLE CUTTER
(FR) ORGANE ANNULAIRE DE PERÇAGE
Abstract:
(EN) The present invention discloses an annular hole cutter (10) particularly useful for cutting railroad rails. Railroad rails are extremely hard and normally require drills or cutters which have carbide inserts. The present invention provides uniquely designed cutter (10) with an improved cutter geometry, flute design and thin wall construction to allow the annular cutter (10) to be used with a lower horsepower drill motor making the drill motor portable resulting in a portable rail cutting system.
(FR) Cette invention a trait à un organe annulaire de perçage (10) des plus utile pour couper des rails de voie de chemin de fer. Ces derniers sont extrêmement durs par nature et exigent normalement l'emploi de forets ou de fraises au carbure. Cette invention porte sur un organe de perçage unique (10) à géométrie utile, goujure et structure à paroi mince améliorées, et, partant, utilisable avec un moteur de foreuse de faible puissance. Ce moteur de foreuse étant lui-même portatif s'intègre dans un dispositif portatif de découpage de rails.
