Abstract

Ledekile (60) for styring av et freseverktøy (30) i et rørforet borehull (9). Ledekilen har en styreflate (28) for styrende kontakt med freseverk-tøyet. Styreflaten danner en første skråvinkel med ledekileaksen og en større skråvinkel med ledekileaksen i det punkt hvor freseverktøysenteret når innerveggen av foringsrøret, hvorved freseverktøyets midtpunkt for-flyttes hurtigere langs foringsrørveggen.
