Sandvik Coromant Cutting Tools — Complete Product Guide

Summary

Sandvik Coromant is the cutting-tool arm of Sandvik AB, a Swedish industrial group. Headquartered in Sandviken, Sweden, with global production in Sweden, Italy, the Czech Republic, India, China, and the US. Coromant is the research-driven tier-one of the cemented-carbide world — if Kennametal is "pragmatic," Sandvik is "scientific." They publish more machining data, training material, and application guides than any other tooling maker. If you've ever seen a calculator that asks you for Vc, fn, and ap in SI units and returns a specific grade + geometry recommendation, it was probably trained on Sandvik's application model.

In 2024 Sandvik completed the acquisition of Walter AG consolidation and several smaller digital/tooling companies. Walter still operates as its own brand (see the Walter guide); Coromant is the flagship.

What Sandvik Coromant is best for

  • Aerospace and hi-temp alloy machining — Ti-6Al-4V, Inconel 718, nickel superalloys. Their S-classes grades (GC1105, GC1115, GC2220) are top-tier here.
  • Precision turning — the CoroTurn line and the Wiper edge geometry (the -WMX, -WF suffixes) are reference-level for surface finish.
  • Boring — Silent Tools anti-vibration boring bars. Tuned-mass dampers inside the bar. Genuinely a category-leader when you're boring 4:1 L/D or deeper.
  • Production milling — CoroMill 390 (shoulder mill), 490 (high-shear positive face mill), 690 (long-edge), Mill 345 (45° face). All well-engineered with deep grade selection.

If your shop targets aerospace / medical / semiconductor / high-tolerance work, Coromant is the first tier to consider. If you're a pure job shop cutting mostly mild steel and aluminum, Kennametal or WIDIA will be a better value.

Brand architecture

CoroTurn (turning)

Full range of turning tools: CoroTurn 107 (precision), CoroTurn Prime (double-ended), CoroTurn HP (high-pressure coolant delivery). The CoroTurn Prime head gives you a two-direction first-choice turning insert that's worth testing if you do Swiss or sliding-headstock work.

CoroMill (milling)

  • CoroMill 390 — shoulder mill with axial and radial cutting edges, the workhorse
  • CoroMill 490 — positive-rake high-shear face mill
  • CoroMill 690 — long-edge roughing
  • CoroMill Plura — solid-carbide end mill line (Sandvik's answer to Harvey/Helical)
  • CoroMill QD — deep-slot grooving and part-off on milling machines

CoroDrill (drilling)

  • CoroDrill 860 — solid-carbide drilling, top-tier
  • CoroDrill 880 — indexable / insert drill
  • CoroDrill DS20 — high-penetration-rate drilling for tough materials
  • CoroDrill Meister — modular exchangeable-head system (similar concept to Kennametal KenTIP FS)

CoroBore / CoroChuck / Silent Tools (boring, toolholding)

Silent Tools is the famous anti-vibration boring-bar product line. At L/D > 4, they can be the difference between hours of chatter-fighting and a clean-finish first try. Expensive but earn their keep.

Grade families (this is the part most machinists get wrong)

Sandvik's grade system uses four-digit codes starting with GC:

  • GC2xxx series — general-purpose steel turning (ISO P). GC4325 is the reference.
  • GC1xxx series — stainless steel + hi-temp (ISO M / ISO S). GC1115 for titanium finishing, GC2220 for superalloy roughing.
  • GC3xxx / GC3200 series — cast iron (ISO K)
  • GC4xxx series — recent multi-layer PVD/CVD grades. GC4325 (released 2016, still current flagship for P25 applications) is arguably the most-installed carbide grade globally.
  • GC6xxx, GC7xxx — cermet-based, used for finishing

Inveio and Zertivo coating technologies

  • Inveio — Sandvik's CVD texture-controlled coating; aligns the crystal structure of the coating in one direction for superior wear resistance. Used on GC4325 and newer GC-series CVD grades.
  • Zertivo — newer PVD technology for edge retention on interrupted cuts. Used on GC4415 and newer stainless/superalloy grades.

Grade selection cheat sheet

Starting points (mid-range):

Material First-pick Sandvik grade Surface speed range
4140 annealed (ISO P) GC4325 650–950 SFM
304 stainless (ISO M) GC2220 400–600 SFM
17-4 PH H1025 GC2220 or GC1115 350–550 SFM
Ti-6Al-4V GC1115 150–250 SFM
Inconel 718 aged GC2220 + ceramic finish 80–150 SFM
Gray cast iron GC3215 650–1000 SFM
6061-T6 aluminum GC H13A (uncoated) 1500–3000 SFM

These are opening values — Sandvik's Application Guide PDF or the CoroPlus ToolGuide web tool will get you a tighter number for your exact operation.

When to use Sandvik Coromant vs. alternatives

  • vs. Kennametal: Sandvik leads on aerospace, precision turning, and boring-bar damping. Kennametal is usually cheaper and more available at US distributors. For general steel work, they're roughly equivalent.
  • vs. Walter: Walter is Sandvik-owned (since 2024). Walter's Tiger·tec grades are very competitive on steel milling and drilling; Coromant leads on turning and aerospace.
  • vs. Iscar / IMC Group: Iscar is the creative-geometry leader. Sandvik is the data-and-engineering leader. Many shops run both.
  • vs. Harvey / Helical: Totally different scope — Harvey/Helical don't make indexable inserts. Sandvik's solid-carbide CoroMill Plura competes there, but enthusiast shops tend to prefer Helical's geometry.

Ask 4man

Sandvik's catalog is deep and their grade codes are the single most-asked "how do I pick?" question in machining. 4man cross-checks their application guide against the material, machine, and tolerance you've told it about — and remembers the grade you ran last time.
