Advantages of the extrem unequal pitch: • Specially suitable for use in aircraft construction • Excellent surface quality due to reduced vibrations. • R eduction of the axial force by 50% and the radial force by 25% results in: – Minimizing the cutting force for more tool life – Less machine load for a longer service life – Excellent for hand-operated use • Optimal chip breaking through relief grinding For countersinking in materials: • High-alloyed chromium steel such as stainless (V2A / V4A) • Acid resistant steel • Steel • Cast iron • Non ferrous metals 3-flat shank for: –  Excellent torque transmission – No slippage in the drill chuck – This results to superior cutting output Art. d1  mm d3  mm l1 mm d2  mm Z AF BF I 6.3 1.5 45.0 5.0 3 – M 3 I 8.3 2.0 50.0 6.0 3 – M 4 I 10.4 2.5 50.0 6.0 3 – M 5 I 12.4 2.8 56.0 8.0 3 – M 6 Art. d1  mm d3  mm l1 mm d2  mm Z AF BF I 16.5 3.2 60.0 10.0 3 – M 8 I 20.5 3.5 63.0 10.0 3 – M 10 I 25.0 3.8 67.0 10.0 3 – M 12 Unequal pitch 1581 Cutting data Movie HSS-XE countersink, unequal pitch, DIN 335 type C 100°, 3-flat-shank Advantages of the extrem unequal pitch see page 683 Alu Steel Stainless Copper, brass, tin Plastics GRP/CRP Grey cast iron APPLICATION Hardox 450 Hardox 400 new new new < 900 N < 900 N > 10% Si 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
