A 16 mm damped turning bar enquiry needs a complete dimensional and component record. The 16 mm measurement identifies the listed bar diameter, but it does not define catalogue length, the compatible head, the connection field or the required installation arrangement. Check those fields before treating a replacement candidate as the same item already used in a setup.
The WT16 C16-156 record provides a specific example. This guide turns its confirmed fields into a purchasing reconciliation checklist. It does not describe every 16 mm damped bar, establish a universal installation rule or claim a particular machining result.
Keep the model, diameter and head designation distinct
The WT16 C16-156 damped turning bar lists bar diameter d as 16 mm and catalogue length L as 156 mm. Its compatible head designation is WT16. The connection G field is recorded as G1/8.
Do not read every part of the model into an assumed technical meaning. The labelled fields establish which measurements and designations are confirmed. Retain the exact product identity alongside those fields so that a quotation does not silently substitute another configuration with a similar-looking code.
| Identity or dimension field | Confirmed record |
|---|---|
| Product identity | WT16 C16-156 damped turning bar |
| Bar diameter d | 16 mm |
| Catalogue length L | 156 mm |
| Compatible head designation | WT16 |
| Connection G | G1/8 |
A supplier response should identify the same product or explicitly state a proposed alternative for separate review. Matching the diameter alone does not establish that the head arrangement, connection or installed position is equivalent.
Interpret the clamping calculation without changing its meaning
The catalogue note states that the clamping-section length equals four times the bar diameter. Applied to the listed 16 mm diameter, the arithmetic is 4 × 16 mm = 64 mm. The 64 mm result is a calculation from that note, not an independently measured drawing dimension.
Keep this distinction on the check sheet. The note concerns clamping-section length for the specific bar. It is not a maximum-overhang ratio, a bore-depth rating or a rule to apply to every product described as a 16 mm damped bar. Obtain the applicable installation instructions to establish how the note is implemented in the actual holder.
Do not subtract the calculated clamping section from catalogue length and advertise the remainder as usable reach. Such a calculation would omit unverified datums, head geometry and installation constraints. A straightforward subtraction can still be technically misleading when the component relationships are unknown.
Reconcile the holder requirement before ordering
Provide the intended holder identity and its relevant drawing. Ask which bar surfaces the holder is meant to contact and how the named bar is installed. Where the available record does not establish those details, preserve the uncertainty as a specific installation question.
The 16 mm diameter is not by itself evidence that any nominally matching holder is suitable. Clamping geometry, installation instructions and the actual assembly must resolve that evaluation. Do not infer a tightening value or approved contact arrangement from an illustration of another holder.
If replacing an installed bar, document its orientation and the head position. Include photographs that show the existing assembly rather than only the removed component. Mark any restricted installation space on the part or setup drawing so that the enquiry asks a checkable geometry question.
Specify the head and supplied components
The compatible head designation WT16 is part of the record, but it does not establish that a head is included in the bar purchase. Ask whether the quotation is for the bar alone and identify any required head, insert or other accessory separately.
Likewise, retain G1/8 as the named connection field. Do not turn it into an unsupported pressure, flow or machine-connection claim. If the proposed assembly needs a connection to perform a particular function, request the relevant component documentation rather than assigning that function from the abbreviated field alone.
The full cutting configuration also needs a workpiece requirement. Provide the intended operation, material, feature dimensions and quantity. No insert grade, speed, feed, tolerance capability or vibration-reduction value is established by the dimensional record used here.
Close the purchase record with verified answers
Use the turning tools catalogue to keep the selected product attached to the enquiry, then send the reconciliation checklist through the contact page. State which fields are already confirmed and which require a drawing or installation document.
The final quotation should identify the product, quantity and included components while answering the installation questions that affect acceptance. Preserve the source of the 64 mm clamping calculation and the exact catalogue note. This produces a repeatable purchasing record without presenting an arithmetic result or nominal diameter as a guarantee of installed reach or performance.
Frequently asked questions
What is the documented length of the example 16 mm bar?
Its catalogue length L is 156 mm. That is not a verified usable-reach or bore-depth rating.
Where does the 64 mm clamping figure come from?
It is the labelled calculation 4 × 16 mm from the catalogue note that clamping-section length equals four times bar diameter. The applicable installation instructions must establish its implementation.
Does WT16 establish that a head is included?
No. WT16 is the compatible head designation in the record. Head, insert and accessory inclusion must be stated separately in the quotation.
