Long Reach Multi-Function Indexable Boring Bar

RONGKE is a China manufacturer offering the Long Reach Multi-Function Indexable Boring Bar for buyers who need to confirm the documented 3.25D working length and required projection. The documented longer TCAP multifunction option is 3.25D, paired with the same diameter-specific XCMT inserts as 2.25D. This page uses that longer standard as its reference; any greater special reach needs a confirmed drawing.

How the Assembly Works

This page treats 3.25D as the longer catalog TCAP configuration. Requested projection should be checked against its actual L1 dimension; a greater special reach requires an agreed drawing.

Key Facts at a Glance

Four Checks Before Ordering

Use the documented longer TCAP series

The supplied table lists 3.25D as the longer standard option. Other long-reach dimensions need a confirmed drawing and are not established by this keyword.

Check actual L1 and LS dimensions

The Ø20 mm 3.25D model lists L1 65 mm and LS 131 mm. Use L1 for the working-length reference, while reviewing the full tool envelope separately.

Review runout and operation clearance

Check the clamped bar at the intended projection and review drilling, boring, facing and turning paths individually. Increased reach does not establish unrestricted lateral access.

Keep insert and coolant interfaces size matched

The Ø20 mm example uses XCMT10T304 and G1/8. Retain these size-specific interfaces when selecting the longer version rather than transferring another diameter's parts.

Application Fit

Choose the Long Reach Multi-Function Indexable Boring Bar when the job calls for the documented 3.25D working length and required projection. Use the documented 3.25D TCAP option when the compact version lacks the required working reach. Confirm the full motion envelope before combining drilling and turning operations on the same setup.

Selection guide — Longer standard vs unlisted special TCAP: 3.25D is documented alongside 2.25D. A longer custom version needs a confirmed drawing; no 5D or 8D multifunction range is established by this catalog table.

FAQ

1. Q: Does long reach mean a documented 5D or 8D TCAP series?

A: No. The documented longer option is 3.25D; greater special reach needs its own confirmed drawing.

2. Q: Is LS 131 mm the available working length?

A: No. The cited Ø20 mm model has L1 65 mm; LS 131 mm describes the separate catalog length dimension.

3. Q: What changes should be reviewed when extending multifunction reach?

A: Review the clamped working-end alignment and the full envelope for every planned operation.

4. Q: Does greater reach require a different insert system?

A: No. At the cited Ø20 mm size, the longer standard retains XCMT10T304 and G1/8.

Inspection and Supply Details

Production & inspection

For this order, inspection should address longer TCAP L1/LS identification, insert position and working-envelope clearance at the selected projection. Add the required tolerances to the purchase drawing before agreeing an acceptance record.

Quotation Checklist

Use the documented 3.25D working length and required projection to define a replacement enquiry for the Long Reach Multi-Function Indexable Boring Bar. Confirm item quantities with RONGKE before accepting the supplier factory quotation.
