USER GUIDE
ISOTURN INSERTS Ceramic Cutting Tools IS80 CVD Coated Si3N4

High Speed Rough Turning on Grey Cast Iron
• Multi-layered coating on IS8 matrix
• Roughing and interrupted cutting of cast iron

* Coolant is not recommended for interrupted cutting
IS9 Si3N4
Turning Nickel Based Alloys
• Very tough Si3N4 ceramic grade with high cutting edge stability
• Machining on nickel based high temprature
alloys, in roughing to finishing applications
• Honing is the standard edge preparation

IW7 AL2O3+Sic Whiskers
Main Advantages Cutting Speed (m/min)
• High hardness (HV 2,100)
• High fracture toughness due to SiC (silicon
carbide) whisker - reinforced ceramics 450
• Excellent thermal shock resistance, which enables
using coolant and interrupted cut machining
• Excellent for roughing and semi-finishing operations at 8-10 IW7
times faster cutting speeds when compared with carbide grades
• Good oxidation resistance due to its alumina substrate
