01 — Product Range
Everything below is factory-direct from China, quality-controlled at source, and supported from Switzerland. Send us your machine, your spindle, and what you cut — we quote what fits.
02 — CNC Tool Holders
Precision tool holders for demanding milling applications. Every interface family covers the holder types a modern machine shop runs daily — and we match the interface to your spindle before quoting.
| Interface | Holder types | Typical applications |
|---|---|---|
| BT30 · BT40 · BT50 | End mill holders · Shell mill holders · Face mill adapters | General milling on vertical machining centres |
| SK30 · SK40 · SK50 | Collet chucks · End mill holders | European-standard spindles (DIN 69871) |
| HSK63A | High-precision holders for high-speed machining | HSK spindles, high-speed cutting |
Other interfaces and special configurations available on request.
03 — Carbide Inserts
High-performance carbide inserts for a wide range of machining materials. Tell us what you cut and at what parameters — we recommend the insert geometry and grade that fits the job, not just what is in stock.
| Operation | Insert styles | Workpiece materials |
|---|---|---|
| Milling | Square · 45° parallelogram · Round · High-feed geometries | Steel · Stainless steel · Cast iron · Aluminium |
| Turning | 80° and 55° diamond · Triangular · Square · Grooving profiles | Steel · Stainless steel · Cast iron · Non-ferrous |
| Grooving & Parting | Grooving · Cut-off · Thread-turning profiles | Steel · Stainless steel · Non-ferrous |
Standard grades in stock for common materials; application-matched grades available on request.
04 — Precision Collets
Reliable clamping solutions for consistent machining accuracy. Our ER collet series covers the sizes most shops run, with tight clamping runout for repeatable results.
| Series | Clamping range | Typical use |
|---|---|---|
| ER16 | 1 – 10 mm | Small-diameter tools, light milling and drilling |
| ER20 | 1 – 13 mm | General-purpose milling and drilling |
| ER25 | 1 – 16 mm | Mid-size tools on machining centres |
| ER32 | 2 – 20 mm | Heavy milling, larger tool shanks |
Metric and inch clamping sizes available on request.
05 — Tooling Accessories
Precision-manufactured accessories for CNC systems — the small components that keep your spindle and holders working together, made to match the interfaces we supply.
| Accessory | Description | Fits |
|---|---|---|
| Pull studs | Retention screws matched to holder interface and spindle spec | BT · SK holders |
| Retention knobs | Threaded retention components for holder clamping | BT · SK holders |
| Components | Washers, nuts and supporting components for ER clamping systems | ER16 – ER32 collet systems |
Send us the interface and spindle specification — we match the accessory to it.
