SECO 4mm 6deg R/H Part Off Insert
-16 Chipbreaker First choice for steel and cast iron in difficult conditions and/or high feed rates.
20° positive cutting rake angle.
Strong protection chamfer.
T25M - Tough versatile CVD-coated grade intended for parting-off of steel, stainless steel and cast iron at moderate cutting speeds.
The R-/L-inserts have a setting angle of 6° in order to eliminate burrs and minimize the parting-off pip left on the workpiece. To reduce pip size with N-inserts, use the smallest width possible. The correct centre height is another major factor to avoid pips (control to ±0.1 mm).
When using R-/L-inserts, the feed rate should be reduced by approximately 30%.
Convex or concave surfaces will be avoided, when using right or left hand inserts, by reducing the feed rate.
