Technical data
From catalogue code to cutting conditions.
Grades, coatings, designation logic, starting values and shop-floor formulas live here as structured web content. Each product family repeats the relevant subset beside its range.
01 / Selection layer
Grades & coatings
Start with the workpiece group, then balance wear resistance against toughness and edge sharpness.
Stainless steel
Sharp edges and dependable toughness
Cast iron
Wear resistance in abrasive materials
Non-ferrous
Polished geometry and low adhesion
Heat-resistant alloys
Thermal stability and edge security
Hardened materials
Stable finishing at high hardness
Sharp and impact-resistant
Thin coatings retain a sharper edge and suit cyclic loading in milling, drilling and interrupted cuts.
Demo families: TiAlN · TiNWear-resistant in stable cuts
Thicker multilayer coatings support crater-wear resistance in continuous or lightly interrupted turning.
Typical layer stack: TiN · TiCN · Al₂O₃02 / Application layer
Starting cutting data
Searchable, filterable starting points belong on the site; detailed printable tables can also remain in Downloads.
| Operation | Material | vc, m/min | Feed, mm | Engagement |
|---|---|---|---|---|
| Solid milling | ISO P steel | 140–220 | fz 0.04–0.10 | ap ≤ 1.0×D · ae 10–40% D |
| Indexable milling | ISO P steel | 160–240 | fz 0.08–0.18 | Set by insert and cutter engagement |
| Solid drilling | ISO P steel | 80–140 | fn 0.10–0.24 | Reduce for deep holes and poor runout |
| Turning | ISO P steel | 160–260 | fn 0.12–0.30 | ap 0.5–3.0 mm |
| Slitting / cut-off | ISO P steel | 90–160 | fz 0.03–0.08 | Check kerf, overhang and radial engagement |
Demonstration values only. Final values depend on the manufacturer's grade, geometry, machine, holder, coolant, workpiece condition and required tool life.
03 / Catalogue logic
Product designation
The same pattern works for inserts, solid tools, drills and cutter bodies—even when each family uses its own code structure.
ISO-style
Turning insert designation
Shape, clearance, tolerance and edge geometry can be read before opening an individual insert.

04 / Shop-floor utility
Core formulas
Compact calculation logic turns catalogue values into machine inputs without forcing the customer to leave the product journey.
n = 1000 × vc / (π × D)n rpm · vc m/min · D mm
vf = fz × z × nvf mm/min · fz mm/tooth · z teeth
vf = fn × nfn mm/rev · n rpm
Ra ≈ fn² / (8 × rε)Theoretical geometry only; machine and edge condition also matter.
