Z-Type Outer Indexable Inserts for Large Diameter Drills

RONGKE supplies the Z-Type Outer Indexable Inserts for Large Diameter Drills as a drilling-tool manufacturer in China. Start the purchase specification with the ZPMT size assigned to each peripheral cutting position. Z-type outer inserts are peripheral cutting components for the matching Z-series assembly. The catalog model codes use ZPMT, with straight and wavy cutting-edge options. Confirm the model code and pocket dimensions when ordering replacements.

Configuration Overview

A Z head may carry more than one ZPMT insert size. Record each pocket position against its insert reference before placing a mixed replacement order.

Key Facts at a Glance

Selection Checklist

• Use ZPMT codes to identify the Z insert

The actual references are ZPMT040310, 050312, 060312, 070416 and 090520. Confirm the code even where the catalog heading is inconsistent.

• Check the Z size dimensions

ZPMT070416 lists L10 18 mm, W 14.5 mm, D1 4.4 mm, S 4.75 mm and R0.8. Match the complete pocket dimensions.

• Specify the cutting-edge suffix

Choose the documented -W straight or -WP wavy option for the application. Retain the suffix with the size and grade on the replacement order.

• Confirm the head's mixed-size arrangement

Some larger Z heads combine outer-insert sizes. Identify the worn position and the head row rather than ordering one assumed size for every pocket.

Machining and Setup Considerations

Choose the Z-Type Outer Indexable Inserts for Large Diameter Drills when the job calls for the ZPMT size assigned to each peripheral cutting position. These inserts replace the outer cutting edges of the matching large-diameter drill head. Order the full ZPMT code, including edge-style suffix, so that the replacement retains the specified pocket fit and cutting geometry.

Selection guide — ZPMT vs WOMT: choose ZPMT for the Z outer system and follow the printed part code despite the inconsistent table heading. Equal R0.8 corner notation does not establish matching seat geometry.

Quality and Replacement Support

Production & inspection

The relevant acceptance points are ZPMT dimensional identity, edge suffix and position-specific fit in a mixed-size Z head. These checks should be specified for the selected assembly; request the required records when placing the order.

FAQ

1. Q: Which code governs selection when the table heading is inconsistent?

A: The actual ZPMT reference and matching pocket drawing govern selection.

2. Q: Is equal corner radius enough to establish compatibility?

A: No. Width, length, thickness, hole and locating geometry must also match.

3. Q: Can a wavy-edge option be supplied without changing the order code?

A: No. Retain the required edge suffix in the order description.

4. Q: Can a larger Z head require more than one insert size?

A: Yes. Some larger Z configurations combine insert sizes; identify each position from the head table.
