2.25D Multi-Function Indexable Boring Bar

RONGKE is a China manufacturer offering the 2.25D Multi-Function Indexable Boring Bar for buyers who need to confirm the sequence of drilling, boring and turning movements. The 2.25D TCAP multifunction bar supports drilling, boring, facing and external turning with the appropriate setup. Its compact reach suits features close to the clamping position; the catalog offers diameters of 8, 10, 12, 14, 16 and 20 mm.

How the Assembly Works

The compact TCAP body carries a diameter-matched XCMT insert. The programmed feed direction changes between drilling and turning, making clearance for each movement part of setup planning.

Key Facts at a Glance

Four Checks Before Ordering

Select the compact 2.25D working length

For D 8, 10, 12, 14, 16 and 20 mm, catalog L1 is 18, 22.5, 27, 31.5, 36 and 45 mm respectively. Choose around the actual feature.

Match the single XCMT cutting insert

The TCAP table pairs each diameter with one XCMT size, from 040104 to 10T304. This is a multifunction insert arrangement, not separate inserts for each operation.

Choose right or left hand for the path

Select the R or L body to match the permitted feed directions. Check the drilling, boring, facing and external-turning movements separately.

Confirm the size-specific coolant thread

D 8 and 10 mm use G1/16; D 12–20 mm use G1/8. Select the matching adapter and verify fluid access through the holder.

Application Fit

Choose the 2.25D Multi-Function Indexable Boring Bar when the job calls for the sequence of drilling, boring and turning movements. The compact 2.25D TCAP option serves compatible drilling, boring, facing and external-turning sequences within its listed working length. Choose the R/L version for the intended movements.

Selection guide — 2.25D vs 3.25D TCAP: at Ø16 mm, working length is 36 versus 52 mm. Both use XCMT080304 and G1/8; choose the reach and R/L orientation needed for the planned operation sequence.

FAQ

1. Q: What working lengths does the 2.25D series provide?

A: L1 is 18, 22.5, 27, 31.5, 36 and 45 mm for D 8, 10, 12, 14, 16 and 20 mm respectively.

2. Q: Does the TCAP bar need a different pocket for every operation?

A: No. The catalog shows one size-matched XCMT multifunction insert; permitted operations still depend on the setup.

3. Q: Can all feed directions be used without checking the hand of tool?

A: No. Select R/L orientation and confirm each intended feed direction and clearance.

4. Q: Does the smallest TCAP use the same inlet as the Ø20 version?

A: No. Ø8/10 uses G1/16, while Ø12–20 uses G1/8.

Inspection and Supply Details

Production & inspection

For this order, inspection should address 2.25D L1 dimension, R/L orientation and the size-matched XCMT pocket fit. Add the required tolerances to the purchase drawing before agreeing an acceptance record.

Quotation Checklist

Confirm the sequence of drilling, boring and turning movements before requesting a factory price for the 2.25D Multi-Function Indexable Boring Bar. Give RONGKE your supplier order reference for repeat purchases.
