Internal Coolant Multi-Function Indexable Boring Bar

RONGKE supplies the Internal Coolant Multi-Function Indexable Boring Bar as a drilling-tool manufacturer in China. Start the purchase specification with the diameter-specific G1/16 or G1/8 coolant connection. The internal-coolant TCAP bar supplies fluid through the body to the insert area during multifunction machining. Select the insert and body size first, then match the G1/16 or G1/8 coolant connection listed for that size.

Configuration Overview

TCAP directs coolant toward the insert through the size-specific threaded inlet. G1/16 applies to Ø8–10 mm and G1/8 to Ø12–20 mm in the supplied specification, independently of the chosen working-length series.

Key Facts at a Glance

Selection Checklist

• Match G1/16 or G1/8 to body diameter

The TCAP coolant interface is G1/16 at D 8–10 mm and G1/8 at D 12–20 mm. Record the actual thread on the order.

• Choose 2.25D or 3.25D independently

Internal coolant is listed for the TCAP family. Select one of the two depth series according to working length, not as a separate coolant-only size range.

• Review delivery at the multifunction edge

Confirm that coolant reaches the XCMT insert in the intended setup. Include the holder connection and outlet condition in the agreed functional check.

• Separate operation-specific clearances

Plan drilling, boring and turning with the chosen R/L body. Internal coolant supports delivery but does not remove geometric clearance requirements.

Machining and Setup Considerations

Choose the Internal Coolant Multi-Function Indexable Boring Bar when the job calls for the diameter-specific G1/16 or G1/8 coolant connection. This TCAP selection focuses on coolant transfer to the multifunction insert. Match the G thread, body diameter and working length to the holder and the planned operation sequence.

Selection guide — Coolant size comparison: TCAP Ø8/10 uses G1/16, while Ø12/14/16/20 uses G1/8. Both 2.25D and 3.25D are in the same internal-coolant family; select reach separately.

Quality and Replacement Support

Production & inspection

The relevant acceptance points are TCAP G1/16 or G1/8 thread fit, outlet delivery and leakage at the selected holder connection. Agree coolant medium, assembly condition and acceptance criteria before a flow or leakage check; specify pressure and duration separately if a pressure test is requested. These checks should be specified for the selected assembly; request the required records when placing the order.

What to Send Our Factory

For factory supply of the Internal Coolant Multi-Function Indexable Boring Bar, the key purchasing detail is the diameter-specific G1/16 or G1/8 coolant connection. Send RONGKE the component codes so the supplier quotation covers the intended item.

FAQ

1. Q: Which internal-coolant thread applies to the selected TCAP size?

A: Use G1/16 for D 8–10 mm and G1/8 for D 12–20 mm.

2. Q: Is internal coolant limited to one TCAP length series?

A: No. The catalog family includes both 2.25D and 3.25D.

3. Q: What should the coolant check cover on a multifunction setup?

A: Check transfer through the holder and delivery at the actual XCMT cutting position, under agreed conditions.

4. Q: Does through-coolant capability authorize any cutting direction?

A: No. Feed direction and geometric clearance still depend on the R/L body and application.
