Troubleshooting Full Grade Chart

Even with high-end tooling from Mitsubishi Materials and CERATIZIT, things go wrong. Here are the most common Full Grade Chart-related issues our technical team sees, and how to fix them.

Problem: Burned tools after 10-15 parts

Diagnosis: Your surface speed is likely too high. Even Mitsubishi Materials AlTiN-coated carbide can't outrun excessive heat generation. Check that your Full Grade Chart matches the actual material hardness — a shift from HRC 28 to HRC 32 4140 changes everything.
Fix: Reduce SFM by 15-20%. Verify coolant concentration with a Mitutoyo refractometer (target 8-10% for steel).

Problem: Poor surface finish, especially in corners

Diagnosis: Your Full Grade Chart might be fine for straight cuts, but corner engagement increases dramatically. CERATIZIT application engineers call this the "corner trap" — the tool sees 180° of engagement in a 90° internal corner.
Fix: Add a finish pass at 0.1mm radial depth with a separate finishing tool. Program the Grob to reduce feed rate to 50% in corners.

Problem: Inconsistent results across tool brands

Diagnosis: You're applying Mitsubishi Materials Full Grade Chart values to CERATIZIT tools — or vice versa. Each manufacturer's carbide substrate and coating system has a different sweet spot.
Fix: Download the specific Full Grade Chart chart for your exact tool from the manufacturer's website. Mitsubishi Materials CoroPlus and CERATIZIT NOVO both offer free digital tools.

Carbide grade classification and cross-referencing guide

Carbide grades are classified by ISO application groups (P, M, K, N, S, H) based on the material they are designed to cut. Within each group, grades range from tough (lower numbers, e.g., P10) to hard/wear-resistant (higher numbers, e.g., P50). This guide helps navigate the grade designations across major manufacturers.

ISO P (Blue): Steel and cast steel. The largest category. P10 = finishing, P25 = general purpose, P40 = roughing/interrupted cuts.
ISO M (Yellow): Stainless steel. M20 = austenitic finishing, M30 = general purpose, M40 = roughing. Tough grades needed to handle work hardening.
ISO K (Red): Cast iron. K10 = finishing, K20 = general purpose, K30 = roughing. Wear-resistant grades for abrasive cast iron.
ISO N (Green): Non-ferrous (aluminium, copper, brass). Sharp, polished edges. Often uncoated or with thin diamond coatings. PCD preferred for high volume.
ISO S (Brown): Superalloys and titanium (HRSA - Heat Resistant Super Alloys). Tough substrates with heat-resistant coatings (AlTiN, TiAlN). Low speeds, moderate feeds.
ISO H (Grey): Hardened materials (45-65 HRC). CBN or ceramic grades. Used for hard turning instead of grinding.

Frequently asked questions

How do I cross-reference carbide grades between manufacturers?

Use ISO classification as the common language. Start with the ISO code (e.g., P20-P30 for general steel turning). Each manufacturer has grades targeting that range. Sandvik GC4325, Kennametal KCP25B, and Iscar IC8250 are all P25-class general steel grades. They are functionally similar but not identical -- always test before changing suppliers.

Tough vs hard carbide grade -- which should I choose?

Tough grades (higher cobalt binder, larger grain size) resist impact and thermal shock. Use for roughing, interrupted cuts, and unstable setups. Hard grades (lower cobalt, finer grain) resist wear and deformation. Use for finishing, high-speed continuous cuts, and abrasive materials. Start with the manufacturer's "first choice" grade for your material.

What does CVD vs PVD coating mean for grade selection?

CVD (Chemical Vapour Deposition): thicker coatings (5-12 um), deposited at high temperature. Best for steel turning where heat resistance matters. PVD (Physical Vapour Deposition): thinner (2-5 um), deposited at lower temperature, sharper edges. Best for milling, stainless, superalloys, and sharp cutting edges. CVD is generally tougher; PVD keeps a sharper edge.

How to use this Carbide Grade Cross Reference Chart

Use this reference to navigate carbide grade designations. Start with the material's ISO group (P/M/K/N/S/H), then select a grade based on the operation (finishing vs roughing). When cross-referencing, compare the ISO classification ranges, not just the manufacturer's marketing name.

Common mistakes to avoid

Cross-referencing grades by colour or marketing name alone -- always verify the ISO application range matches your material and operation.
Using a finishing (hard) grade for roughing -- the grade will chip on the first interrupted cut.
Not considering coating type when switching grades -- a PVD-coated grade for milling should not be replaced with a CVD grade for turning, even if the ISO code matches.
