Clamping Head Bore Tool
The KORRETTO Clamping Head Bore Tool is a turning fixture for preparing EM machinable rubber-flex collets. It supports bore-to-size preparation so the clamping head can match the required workpiece diameter.
How It Works
Use the turning fixture with the matching EM head during bore preparation. After machining, check the gripping bore and workpiece fit before production. Finished S, R and RL heads are a different option and should not be treated as unrestricted machining blanks.
Selection should confirm the collet type, required bore size, workpiece diameter, machining allowance, tool specification and compatible collet system.
Key Features
EM head preparation
Designed for the corresponding EM machinable clamping head.
Four fixture sizes
TF42, TF52, TF65 and TF80 match the listed EM references.
Bore-to-size setup
Prepare the gripping diameter for a specific workpiece.
Different from a changing tool
This fixture supports machining; a changing tool installs or removes heads.
Typical Applications
- Rubber-flex collet bore preparation
- Matching collet bore to workpiece diameter
- Collet setup and maintenance
- Workpiece-specific collet machining
- Rubber-flex tooling support

FAQ
What is the Clamping Head Bore Tool used for?
It is used to assist bore machining or sizing of segmented clamping heads for a specific workpiece diameter.
Is this a complete chuck?
No. It is a turning fixture used with a compatible EM machinable clamping head.
Is this the same as a changeover tool?
No. A bore tool is used for bore preparation or sizing. A changeover tool is used for collet replacement or changeover operations.
What information is needed for selection?
Provide the collet type, target bore size, workpiece diameter, machining allowance and compatible chuck or collet system.
Can this tool be used with any segmented clamping head?
No. The catalog matches TF42, TF52, TF65 and TF80 to 42EM, 52EM, 65EM and 80EM respectively. Finished heads are not unrestricted machining blanks.
When should I use a bore tool?
Use it to prepare the bore of a compatible EM head to the required workpiece gripping size before production.
Does re-boring always improve clamping accuracy?
Not always. The result depends on the collet condition, machining method, machine setup, tooling condition and final trial clamping against the target workpiece.
What information should I send for quotation?
Send the collet model, current bore size, target bore size, workpiece diameter, machining allowance, machine model and any notes about the present bore-matching problem.
