Hole Enlargement (mm) OthersBrazedReamersIndexableIndexableInsert TypeHead TypeSolidDrilling Flat MultiDrills MDF Type Long shanked type (2D) for flat base drilling, hole expansion and burr control in long overhang conditions. ● For drilling with long overhang and to avoid interference with the workpiece *A prepared hole with the same diameter or centring hole with a larger diameter than the tool is needed for drilling with the long type. DC < 6mm, stepped shank DC ≥ 6mm, relief shank J H Type with oil hole (3D/5D) for 2-5D deep hole applications ● Internal coolant supply enables deep flat hole drilling. *A prepared hole with the same diameter or centring hole with a larger diameter than the tool is needed for drilling with an  L/D=5  oil hole.
