What Our Clients Say
хорошее качество очень быстрая доставка приятно иметь с вами дело большое спасибо
John Kim
very good seller and a great quality product. as always
Elton Don
Shuangfengli makes beautifully precise tooling. They are fantastic in communication, providing actionable information, and shipping. Their ground tapers are very nice with excellent finish.

Tool Holders by Spindle Interface: BT, HSK, CAT, NT and VDI
Machine tool holders are chosen by spindle interface first. Our range covers the interfaces used on Asian, European and American machining centres:
- BT (JIS B 6339) — BT30, BT40 and BT50 holders for drilling, tapping and milling; the most common interface on Asian VMCs.
- HSK (DIN 69893) — HSK-A, HSK-E, HSK-F and HSK-T holders with face contact for high-speed and high-precision work.
- CAT / V-flange (ANSI B5.50) — CAT40 and CAT50 holders for machines built to the American standard.
- NT and VDI — lathe tooling, including VDI static and driven holders for turning centres.
Browse HSK-T tool holders and turning-milling tool holders, or send your machine model and we will confirm the interface, pull stud and balance grade.
Milling, Turning and Tapping Tool Holders
Three families cover most metal-cutting operations:
- Milling — collet chucks, shell mill arbors, face mill holders and shrink-fit or hydraulic chucks for high-speed spindles. See milling tools and holders.
- Turning — external and internal turning holders, boring bars and tool sleeves for lathes and turning centres. See turning tools.
- Tapping — tension-compression chucks, rigid tap collets and overload-protection collets that prevent broken taps. See tapping tool holders and tension-compression and rigid tap chucks.
Every holder is quoted with the matching collet, nut and pull stud, so it can be mounted on arrival.
Workholding: Chucks, Vises and Clamping Fixtures
Turning and milling both depend on rigid workholding. The catalogue includes:
- Chucks — three-jaw, six-jaw, front-mounted and special chucks.
- Lathe chucks and accessories — jaws, flanges, cylinders and connection plates.
- Vises and clamping fixtures — self-centering vises, four-hole locators and base plates.
- Workholding — modular fixtures for repeated set-ups.
For production cells, tell us the part envelope and changeover time target; we will propose a fixture set rather than individual items.
Collets and Tool Holder Accessories
Collets and accessories decide the actual runout at the tool tip. We supply ER collets from ER11 to ER50, tap collets with square drive, and the nuts, wrenches and pull studs that go with them.
- Collets and tool holder accessories
- Collet chucks and front-mounted holders
- Centre series — live centres and dead centres for shaft work.
If you are matching an existing holder, send the collet standard and the tool shank diameter — we will confirm the exact size instead of the nearest one.
Industry Applications
Our tooling is used across five main application areas. Each has different priorities for rigidity, runout and changeover:
- Automotive and parts suppliers — high-volume milling and tapping, where tap breakage and cycle time dominate.
- Mould and die — deep cavities and small cutters, where runout and holder clearance matter.
- Aerospace and energy — difficult materials, long overhangs and heavy stock removal.
- 3C and small parts — high-speed spindles with small diameter tooling.
- General machining job shops — mixed batches where one holder must cover many diameters.
Tell us the material, the operation and the machine, and we will shortlist the holder family and the matching collet range.
Quality Control, Lead Time and OEM/ODM
Quality control. Holders are checked for taper contact, runout and balance before packing. Certificates and inspection reports are available on request.
Lead time. Stock items ship in 3–7 days after payment. Made-to-order holders take 15–60 days depending on model and quantity.
OEM/ODM. Private labelling and manufacturing from drawings or samples are supported. Send a drawing with tolerance and material, and we will quote tooling and batch size.
For export orders we ship by international express for small parcels and by sea for bulk. See the contact page for the current address, phone and email.
FAQ
What is your minimum order quantity (MOQ)?
For standard models the MOQ is 1 piece, and single-piece sample orders are welcome. Customized items are quoted per model and specification.
How long is the lead time?
In-stock items ship in 3-7 days after payment. Made-to-order holders take 15-60 days depending on model and quantity.
Do you support OEM and ODM?
Yes. We support private labelling and manufacturing strictly from customer drawings or samples.
Which tool holder interface should I choose?
Match the spindle first: BT for most Asian VMCs, HSK for high-speed and high-precision machines, CAT for machines built to the ANSI standard. Send your machine model and we will confirm.
Are inspection reports available?
Yes. Runout and balance checks are recorded and certificates can be provided on request.
