Modular Deep Hole Drill Extension

RONGKE supplies the Modular Deep Hole Drill Extension as a drilling-tool manufacturer in China. Start the purchase specification with the locating diameters at both ends of the YXZ extension. The YXZ MDD extension connects compatible modular components and lists lengths of 200, 300, 400 and 500 mm. It is distinct from the DXZ machine-side connecting shank. Interface diameters and the applicable MDD head group define its fit.

Configuration Overview

YXZ is an intermediate reach component. Both locating ends must match the surrounding MDD parts; a suitable overall extension length alone does not establish assembly compatibility.

Key Facts at a Glance

Selection Checklist

• Distinguish YXZ extension from DXZ shank

YXZ is the extension between modular components; DXZ is the machine-side connecting shank. Their different functions matter even when listed lengths overlap.

• Choose a listed YXZ length

The extension table lists 200, 300, 400 and 500 mm. For YXZ-3016200, L is 200 mm, D is 30 mm and D1 is 16 mm.

• Match the applicable aperture group

YXZ-3016 belongs to the Ø45–55 mm group. Match both locating diameters and the catalog aperture group before pairing it with an MDD head.

• Check the assembled connection and coolant route

Include the head, extension and connecting shank in the assembly drawing. Verify joint seating and fluid continuity at the actual chosen length.

Machining and Setup Considerations

Choose the Modular Deep Hole Drill Extension when the job calls for the locating diameters at both ends of the YXZ extension. This component is used when the existing modular drill needs additional reach or clearance. The cutting head continues to determine the hole diameter; the extension is chosen around the connection and assembled length.

Selection guide — YXZ vs DXZ: YXZ extends a modular assembly and lists 200/300/400/500 mm; DXZ connects toward the machine and lists 100–500 mm in 50 mm steps. Length overlap does not make the two parts interchangeable.

Quality and Replacement Support

Production & inspection

The relevant acceptance points are YXZ locating diameters, joint faces and assembled runout with the intended MDD head. These checks should be specified for the selected assembly; request the required records when placing the order.

FAQ

1. Q: Are YXZ and DXZ two names for the same component?

A: No. YXZ is the extension and DXZ the machine-side connecting shank.

2. Q: Does the YXZ table list a standard 100 mm extension?

A: No. The supplied YXZ table begins at 200 mm.

3. Q: Is extension outside diameter the cutting-hole diameter?

A: No. For example, D 30 mm and D1 16 mm identify the YXZ-3016 connection group for Ø45–55 mm holes.

4. Q: Does extension length alone give the final usable reach?

A: No. Include the head, other connection components and engagement in the assembly calculation.
