Clamping Holder D103TM (DDNNN 2525 Tool Holder)

The Clamping Holder D103TM is a precision Tool Holder for turning operations, optimised for DNMG 1104 Indexable Inserts and designed to deliver secure clamping and consistent Cutting performance.

• Clamping Holder DDNNN 2525 ISO design
• Fits DNMG 1104 indexable inserts
• Cutting Angle 62.5° for predictable chip flow
• Overall Length 150 mm for extended Reach
• Includes U Plate TA030 and M4x11 fixing screw

Reliable clamping for predictable machining results

The Clamping Holder combines a compact 25 mm profile with a robust Clamping interface to keep the Insert steady under load. With a Cutting Angle of 62.5°, the geometry promotes controlled Chip Flow and reduces radial shocks during cuts, which helps maintain Surface Finish and prolong Insert life. The secure Verriegelungsschraube M5 and the matched U Plate TA030 ensure repeatable seating and fast tool changes without compromising accuracy.

Practical interface with standard components

Engineered for straightforward integration, the holder uses common fixings such as U Plate Screw M4x11 and a clamping Wedge BK024, making it simple to replace or reconfigure in existing tool assemblies. The supplied Allen key set (3 Allen) supports routine mounting and torque checks. This familiar hardware approach reduces setup time and keeps workshop logistics efficient while supporting consistent clamping forces for reliable Turning operations.

Designed to support efficient turning cycles

At an Overall Length of 150 mm and a Cutting Head Width of 25 mm, this tool offers access to deeper bores and extended profiles without sacrificing rigidity. The moderate Cutting Height of 38 mm balances strength with clearance, helping to prevent chatter in light to medium-duty roughing and finishing passes. For users seeking a predictable machining window, the geometry delivers performance gains through better tool stability and repeatable cutting conditions.

Clear compatibility and easy specification

The holder is specified as DDNNN 2525 and is suitable for the widely used DNMG 1104 Insert format, making it a practical choice for workshops that rely on standard Indexable Inserts. "Indexable Insert" refers to a replaceable cutting tip that can be rotated or replaced when worn, reducing downtime and tooling cost. The product therefore supports a cost-efficient approach to turning where tool life and quick recovery are priorities.

FAQ

What Inserts fit this holder?
The Clamping Holder D103TM from Teknik Makina is designed to accept DNMG 1104 Indexable Inserts; the DDNNN 2525 specification ensures correct seating and orientation for these Insert types.

Which screws and plates are required for mounting?
Mounting uses the U Plate TA030 together with the U Plate Screw M4x11 and the Locking Screw M5; the package is compatible with standard clamping assemblies and can be tightened using the supplied 3 Allen key set.

Can this holder reach into deeper grooves or bores?
Yes. With an Overall Length of 150 mm and a Cutting Head Width of 25 mm, the D103TM provides extended Reach while maintaining rigidity for stable Turning, suitable for many general workshop applications.

How does the Cutting Angle affect machining?
The 62.5° Cutting Angle on the D103TM promotes predictable Chip Flow and reduces radial impact on the Insert, which helps to improve Surface Finish and extend Insert life during both roughing and finishing passes.

Is the DDNNN 2525 compatible with other standard toolblocks?
The ISO designation DDNNN 2525 and the specified Mounting Shank M11 make the holder compatible with common toolblock configurations; confirm dimensions against your lathe tooling to ensure full compatibility.
