KNUX160405L11 QG7215 standard carbide (with coating) turning inserts with two cutting edges
K - quadrilateral shape of turnining insert - parallelogram (55°)
N - Insert without free angle (0°) under the main cutting edge
U - Tolerances and dimensions of turning inserts
X - No hole through insert and a special chipbreaker
16 - Length of cutting edge 19,7mm
04 - Height (thickness) of insert 4.76mm (from bottom of the insert to the top of the cutting edge)
05 - Nose radius R0.5mm
L - Orientation of insert is Left
QG7215 - ISO Grade M20 - The type of carbide grade and the coating on inserts is originally intended for turning stainless steel, it also performs when turning other alloys.
Material: ISO grade carbide (tungsten):
For steel M10-30(between wear resistance and shock resistance)(See ISO grade tables.)
PVD coating - thinner more precise layer coating
Feed speed in mm/rev- 0.1-0.
Cut depth - 0.3mm - 5.0mm
Cuting speed - 220 - 360m/min
Turning insert feature:
Strong cutting edges best reliability and long endurance.
Geometry of KNUX turning insert is shaped so, that many times this inserts are used in cases that other inserts are making noise or poor surface.
Inserts have negative along the cutting edge and positive flank along the narrow edge.
Recommended for all purposes and applications.
Tips and Tricks:
For rough turning it is recommended to use inserts with bigger nose radius (likeR1.0), so wear, force and heat is distributed over larger surface - which makes inserts more durable.
For finishing it is recommended to use inserts with smaller nose radius (like R0.5), with that we reduce preasure on insert, increase cutting abilities, reduce vibration and we make better finishing surfaces.
