When the center cutter needs replacement, RONGKE Carbide Center Tips for Large-Diameter Phoenix Combined Drills supports selection around the center-tip diameter rather than the finished large-hole diameter. Contact us for supplier quotations. Choose PDPA, PDGA or PDMA with the matching center seat and locking screw. Finished large-hole diameter does not identify the replacement tip size.

For Z-head replacement insert orders, RONGKE Z-Type Outer Indexable Inserts for Large Diameter Drills supports selection around the ZPMT size assigned to each peripheral cutting position. Contact us for spare-tip quotations. Larger heads may combine different insert sizes. Request the full ZPMT code, edge suffix and cutting position so replacement parts match the actual pocket arrangement.

When replenishing peripheral W-type cutting edges, RONGKE W-Type Outer Indexable Inserts for Large Diameter Drills supports selection around the complete WOMT size and edge suffix. Contact us for replacement-part orders. Four catalog sizes include straight (-W) and wavy (-WP) options. Order the complete size, edge suffix and grade to retain the specified pocket fit and cutting geometry.

For replacement of a worn support component, RONGKE Guide Pads for Modular Large Diameter Phoenix Drill supports selection around the support radius and fastener of the GP pad. Contact us for purchase planning. They guide against the hole wall and are distinct from cutting inserts and PT/PD margins. Request the complete pad code, support radius, thickness and matching fastener.

For combined heads built around WOMT pockets, RONGKE W-Type Modular Large Diameter Phoenix Drill supports selection around the WOMT size and edge style of the W head. Contact us for bulk orders. The cited Ø32 mm head pairs a Ø15 mm center tip with LJ32. Specify the W head, listed reach and straight or wavy outer-insert geometry when requesting a quotation.

When the selected combined head uses ZPMT inserts, RONGKE Z-Type Modular Large Diameter Phoenix Drill supports selection around the ZPMT pocket arrangement of the chosen Z head. Contact us for factory pricing. The cited Ø52 mm head uses a Ø25 mm center tip and LJ50 connection. Order the Z head, cutting components and body as a matched combination.
