Carbide Center Tips for Large-Diameter Phoenix Combined Drills

RONGKE is a China manufacturer offering the Carbide Center Tips for Large-Diameter Phoenix Combined Drills for buyers who need to confirm the center-tip diameter rather than the finished large-hole diameter. This carbide-component page specifically describes the Phoenix combined-drill center tip in the Ø13–34 mm catalog table. It is distinct from the WOMT and ZPMT outer inserts, whose dimensions and pockets are specified separately.

How the Assembly Works

The center tip machines the middle of a combined Phoenix hole. The outer cutters establish the remaining diameter, which explains why the finished hole size cannot be used to order the center tip alone.

Key Facts at a Glance

Four Checks Before Ordering

Confirm that the item is the center tip

This page refers specifically to the combined-drill center component in the Ø13–34 mm table. The broader keyword must not be used for WOMT or ZPMT outer inserts.

Select its own cutting diameter

Choose the center-tip diameter independently of the larger finished hole. Model examples include PDPA-1300, PDGA-1300 and PDMA-1300 for the 13 mm option.

Match seat and locking screw

The table progresses through C, B, A and numbered seats 1–9. Match the center diameter row to the seat and M2.5–M6 locking-screw reference.

Choose the center cutting geometry

Retain the PDPA, PDGA or PDMA series selected for the workpiece. Outer-insert grade selection remains a separate component decision.

Application Fit

Choose the Carbide Center Tips for Large-Diameter Phoenix Combined Drills when the job calls for the center-tip diameter rather than the finished large-hole diameter. These center drill tips are replacement cutting components for compatible Phoenix combined heads. They are selected separately from the outer inserts and guide pads fitted to the same large-diameter assembly.

Selection guide — Center tip vs outer insert: PDPA/PDGA/PDMA center tips use their own Ø13–34 mm diameter table; WOMT/ZPMT components occupy the outer pockets. Neither center diameter nor outer-insert size alone defines the finished large hole.

FAQ

1. Q: Does this center-tip listing also specify every outer carbide insert?

A: No. This page is limited to the center tip; WOMT and ZPMT outer components have separate tables.

2. Q: Is the largest hole diameter the correct center-tip size?

A: No. Use the center diameter specified by the combined-head row.

3. Q: Can the seat be chosen from the finished-hole diameter?

A: No. Select the seat from the center-tip diameter and mating head reference.

4. Q: Does changing the center geometry also identify the outer insert grade?

A: No. The center-tip series and outer-insert grade are separate selections.

Inspection and Supply Details

Production & inspection

For this order, inspection should address center-tip diameter, seat code and locking-screw match independently of finished-hole diameter. Add the required tolerances to the purchase drawing before agreeing an acceptance record.

Quotation Checklist

Contact RONGKE as your supplier for a factory quotation for the Carbide Center Tips for Large-Diameter Phoenix Combined Drills. Specify the center-tip diameter rather than the finished large-hole diameter and list the parts required.
