Three models, three control systems, one goal: fast, safe and repeatable tool changes for both alloy steel and stainless steel shrink fit holders.
Each model uses dedicated software and heating parameters for its target holder material — pick the one that matches your holder fleet, or the M-420 to cover both.

| Model | Holder material | Typical use |
|---|---|---|
| A-420 | Alloy steel | German-style holders, heavy cutting shops |
| S-420 | Stainless steel | Japanese-style slim holders, mold & die shops |
| M-420 | Both materials | Mixed holder fleets — one machine for everything |
Most heaters on the market can only heat one material — e.g. typical German units cannot safely heat stainless holders. Our machines select dedicated parameters per material.
Adjust every heating, fitting and cooling parameter directly on the intuitive color touchscreen.
Simple to operate, powerful underneath — with per-material parameter sets and usage counters.
Surrounding vents blast air right at the heated zone — large flow, high velocity, fast cooldown.
Freely set heating time to match any brand or special holder specification.
Built-in parameters for every standard size — one touch completes heating. Custom auto times fine-tune temperature and extend holder life.
Choose the right parameter set for alloy or stainless holders on the same machine — no second heater needed.
Tell us your holder brands and materials — we'll match the right machine and quote FOB / CIF within 24 hours.
