Drilling Without Compromise

• High stability and efficiency through the use and positioning of the square inserts.
• Better chip evacuation and reduced flute erosion through special tool body surface treatment
• For difficult drilling conditions such as uneven casting surfaces, hardened steel surfaces and interrupted cut.
• Outstanding drilled hold quality with reduction in exit marks.
• Reduced tooling costs through four cutting edges with specially selected substrates and coatings.
• Inside and outside inserts same insert with the same coating is used, same insert screws.
• In-between diameters for example: U10 71940 (Ø19.4 mm 2 X D)
