Hobs: solid or indexable (with soldered carbide inserts), with high quality HSS or carbide cutting edges, often with protective PVD coating. Tools for effective gear machining.

HOBS
We have extensive range of tools, main division of Our assortment, distinguish due to:
Factors influencing quality and price | Tool advantages/Features description |
Tool material (HSS, carbide) | High hardness and wear resistance |
Coating(PVD) and imposition method | Easier chip clearance, less vibration, higher max. temperature, greater durability and longer tool life |
Tool grinding on CNC grinders | Proper geometry, greater sharpness of CE, fewer defects of CE, smoother surface |
Tool mounting (arbor, shank) | In case of shank cutters its causes more elements to make (arbor, tool and shaft) |
Cutting edge geometry (standard / special) | Processing of non-standard shapes |
Tool type (solid/indexable) | Indexable hobs are larger, body material is less expensive beside of solid cutter |
Tolerance (B, A, AA, AAA) | Ability to perform higher quality components |
Module (m:0,5 -40+) | Gear machining from given module range |
Tool dimensions (⌀D, L) | Ability of producing a few items at a same time, greater rigidity processing, processing of larger wheels |
PVD coatings:
PVD tools improve resistance to heat and abrasion: high quality PVD layers offers an advantage in milling. Reduces friction and wear resistance in compare to conventional and HSM milling (“wet / dry” machining). Modern technology provides a smooth coating layer, reducing the friction between evacuated chips, and a tool.
