Coated Carbide Drills for Spot Facing MDF Type
Long Type (L2D)
For flat base drilling in long overhang conditions, hole expansion, burr prevention. For deep flat base drilling and to avoid interference with workpiece.
Drilling that uses the long shank type requires a guide hole of the same
diameter or a centering hole larger than the tool diameter. A
Two types A ØD < 6mm Stepped Shank Products
c B B ØD ≥ 6mm Relief Shank Products c
With Oil Hole (H3D Type / H5D Type)
Support for internal coolant allows for deeper flat hole drilling.
Drilling that uses oil hole L/D=5 requires a guide hole of the same
diameter or a centering hole larger than the tool diameter.
