N - Non-ferrous
S - Heat-resistant

♦ = Supported operation type

Understanding ISO Material Codes

P Steel
P10–P20 → Finishing
200-300 HB • Harder steels
P20–P30 → General purpose
150-280 HB • Medium carbon/alloy
P30–P45 → Roughing
120-220 HB • Softer steels
Lower numbers = Harder steels, stable cuts
Higher numbers = Softer steels, interrupted cuts
M Stainless Steel
M10–M20 → Finishing
150-250 HB • Austenitic SS
M20–M30 → General purpose
180-300 HB • Duplex/Ferritic SS
M30–M35 → Roughing
200-350 HB • Higher strength
Stainless steels - High chip control needed
Work hardens - PVD coatings preferred
K Cast Iron
K10–K15 → Finishing
180-240 HB • Harder cast iron
K15–K20 → General purpose
140-200 HB • Gray/Ductile
K20–K25 → Roughing
120-180 HB • Softer, interrupted
Gray & ductile cast iron
Abrasive - Wear-resistant grades needed
Quick Rule: Lower ISO numbers (10-20) = Finishing with stable cuts. Higher ISO numbers (30-45) = Roughing with interrupted cuts or softer materials.
Understanding ISO Ranges:
When you see a range like P15-P35, it means the insert is versatile and can handle:
  • ✓ P15 (Finishing) - For harder steels with light cuts
  • ✓ P20-P30 (General purpose) - Medium cuts on typical steels
  • ✓ P35 (Roughing) - Heavy cuts on softer steels
The wider the range, the more versatile the insert!

Understanding MGMN Insert Types

The type letter in MGMN inserts (G vs M) indicates the insert profile and use case:

G Groove Type
  • • Groove only
  • • Often sharper cutting edge
  • • Designed for lighter cuts
  • • Optimal for precision grooving
M Medium-Duty Type
  • • Medium-duty operations
  • • Can handle more feed rate
  • • Suitable for deeper cuts
  • • More robust for tougher conditions
Quick Tip: Choose G-type for precision work and lighter cuts. Choose M-type for more demanding operations with higher feeds or deeper grooves.

Recommended Application

MGMN

MGMN Carbide Grooving Insert - For External and Face Grooving **TYPE: Single-ended grooving insert** MGMN is the most common grooving insert: • Application: External grooving, face grooving, parting • Blade widths: 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm • Single cutting edge per insert • Neutral geometry (can cut left or right) OPERATIONS: ✓ External grooving - creating O-ring grooves, snap ring grooves ✓ Face grooving - grooves on face of workpiece ✓ Parting / Cut-off - separating parts ✓ Chamfering MATERIALS: Steel, Stainless Steel, Cast Iron Compatible holders: MGEHR, MGEVR, MGIVR, MGFVR, MGHH
