-
Manual Chucks
For trial cuts, maintenance changeovers and small-batch turning when a simple, quick-setup external clamp is enough.
View manual chuck series → -
Hydraulic Chucks
For CNC lathe batch production with stable clamping force when paired with a rotary hydraulic cylinder.
View hydraulic chuck series → -
Special Hydraulic Chucks
For valve bodies, pipe fittings and heavy cuts where pull-down, ball-lock or thread-specific clamping is required.
View special hydraulic chucks → -
Pneumatic Chucks
For lathes with a clean air supply and fast, low-maintenance clamping on vertical or horizontal lines.
View pneumatic chuck series → -
Rubber-Flex Collet Chucks
For thin-wall rings, delicate finishes and plated parts where wider circumferential contact reduces marking risk.
View rubber-flex collet chucks → -
Expanding Mandrels
Locates and clamps on the internal bore for bearing seats, sleeves and other bore-driven turning jobs.
View expanding mandrel solutions → -
Collet Chucks
For small-diameter shafts and discs in precision turning; thin-wall parts may pair with diaphragm-style routes.
View collet chuck series → -
Diaphragm Chucks
For thin-wall and surface-sensitive parts that need controlled force and repeatable positioning.
View diaphragm chuck series → -
Indexing Chucks
For multi-face turning on the spindle, such as valve bodies and pipe fittings that need in-process angular indexing.
View indexing chuck solutions → -
Vises
For side clamping and alignment in milling and drilling on machining centers and manual mills.
View machine vise series → -
Dividing Heads / Rotary Tables
For angular positioning on the machine table, complementary to spindle-side indexing chucks in turning.
View rotary table solutions → -
Drill Chucks
For drilling, tapping prep and light-duty tool holding with quick changeover across common tapers.
View drill chuck series → -
Magnetic Chucks
For fast holding of flat parts in grinding and milling where large-area magnetic clamping helps throughput.
View magnetic chuck solutions → -
CNC Tool Holders
For high-rigidity tool clamping on machining centers, including HSK, BT/BBT, SK and hydraulic holder options.

Even if the exact series is unclear, describing the machine interface, workpiece profile or process pain point against the five dimensions below can narrow the options before you contact engineering.
Actuation
Manual, hydraulic or pneumatic?
Compare force control, cycle time and available shop power (hydraulic unit or air).

Workpiece type
Disc, shaft, flange or valve body / pipe?
Irregular profiles often need oriented clamping, seal-face clearance or special jaws.

Machine & interface
Is the spindle nose and drawbar defined?
Taper, flange, speed and stroke decide through-hole vs solid; milling may add vises, chucks or magnetic tables.

Accuracy & automation
How tight are repeatability, indexing and robot interface?
Repeat positioning, indexing accuracy and loader interface affect indexing chucks and rotary table combinations.

Information to prepare before inquiry
Check and gather the following where possible so sales and engineering can respond with a focused category recommendation.
- Machine model and spindle interface (e.g. A2-5 / A2-6, short taper, flange size)
- Maximum speed, drawbar (pull tube) stroke and whether a rotary cylinder is fitted or planned
- Workpiece drawing or sample photos, material and minimum wall thickness
- Clamping on OD, bore or face, plus target tolerance and surface requirements
- Annual volume, target cycle time or automation / loader interface

- Bar & shaft batch work View manual chucks →
Valve bodies and pipe fittings with multiple angular features may also use special hydraulic chucks. For complex jobs, send the drawing and machine interface together so spindle workholding and table accessories can be reviewed as one package.
FAQ
How should I choose between a chuck, collet chuck and expanding mandrel?
A chuck usually clamps the outside of the workpiece with jaws. A collet chuck provides more surrounding contact for round or small-diameter parts. An expanding mandrel locates and clamps from the internal bore. The best option depends on the workpiece shape, clamping surface, accuracy requirement and machining process.
What information should I send for product selection?
Send the workpiece drawing, material, machine model, spindle nose or table layout, clamping surface, required accuracy, cutting load and expected production volume.
Do you provide standard products only, or custom workholding as well?
KORRETTO supplies standard chucks and workholding products, and can also support custom jaws, special clamping surfaces and project-specific workholding solutions when standard products do not fit the workpiece.
Which product category is suitable for thin-wall parts?
Thin-wall parts usually require careful clamping force distribution. Rubber-flex collets, collet chucks, diaphragm chucks or 6-jaw chucks should be reviewed before using a standard jaw chuck.
Which product category is suitable for automated clamping?
Hydraulic chucks and pneumatic chucks are common choices for automated clamping. The final selection depends on clamping force, air or hydraulic supply, cycle time, machine interface and cutting load.
Can one product category cover all workholding needs?
No. Workholding selection depends on the workpiece, machine, process and production plan. A lathe chuck, collet chuck, expanding mandrel, vise or indexing system may be more suitable depending on the application.
Are product drawings and technical data available?
Yes. Send the product category, machine information and workpiece drawing. We can provide available technical data or help check whether a standard model is suitable.
