150mm DDJNR Turning Holder for DN-- 1504 Indexable Inserts, 93° - Teknik Makina

Turning Holder (Klemmhalter) — Teknik Makina

Turning Holder (Klemmhalter) is a compact lathe toolholder designed for reliable left-hand turning with DN-- 1504 indexable inserts, offering stability and repeatable results in production and workshop environments.

• Teknik Makina Turning Holder DDJNL 2525 model
• Compatible with DN-- 1504 indexable inserts
• 150 mm overall length for extended reach
• 25 x 25 mm shank for stable clamping
• 93° cutting angle for precise left-hand turning

Robust Design for Stable Clamping and Reduced Vibration

The DDJNL 2525 toolholder is engineered to deliver a firm and repeatable clamping interface for DN-- 1504 indexable inserts. With a 25 mm shank width and height, and a 32 mm cutting-head width, the holder minimises flex under load, which results in improved surface finish and longer insert life. This structural stability benefits CNC and manual turning alike, translating geometric rigidity into measurable process consistency for everyday workshop tasks.

Consistent Cutting Performance for Left-Hand Turning

A 93° cutting angle combined with a specified left-hand cutting direction supports controlled chip flow and favourable cutting forces for operations that require left-oriented toolpaths. The geometry reduces radial loading and helps maintain cutting-edge engagement, which can lower the tendency for chatter. For users less familiar with cutting-angle terminology: the cutting angle influences chip formation and tool engagement; a 93° configuration favours strength at the cutting edge while preserving dimensional accuracy.

Practical Applications and Who Benefits Most

This toolholder is ideal for machinists, small-series production and maintenance workshops that require dependable indexable tooling for turning jobs. The compact 150 mm overall length gives extra reach without compromising stiffness, making the holder suitable for medium-reach turning and facing tasks. Users seeking repeatable set-ups and quick insert changes will find the clamping concept reduces downtime and simplifies tool management.

Simple Installation, Adjustment and Maintenance

Mounting and routine care are straightforward: the holder mates with standard tool posts and accepts DN-- 1504 inserts; designated seating surfaces ensure correct insert orientation. The ISO designation DDJNL 2525 denotes the holder form factor and shank size, while the additional reference M15 relates to the attachment interface used for specific boring-bar setups. Regular inspection of clamp screws and seating faces prevents misalignment and secures consistent machining performance over time.

FAQ

Which inserts fit the Turning Holder and how are they secured?
The Turning Holder from Teknik Makina accepts DN-- 1504 indexable inserts; these inserts are seated into the designed pocket and clamped securely by the holder's clamp mechanism to guarantee repeatable positioning and safe cutting under typical turning loads.

Is the Turning Holder suitable for high-speed turning operations?
Teknik Makina's Turning Holder (Klemmhalter) is designed for stable clamping and reduced vibration, which supports higher cutting parameters; however, final speed and feed depend on the chosen DN-- 1504 insert grade, workpiece material and machine capability.

How do I maintain the Turning Holder to ensure long service life?
Regularly check the clamping screw torque, clean seating faces and inspect for wear; with the Teknik Makina Turning Holder, correct maintenance preserves positioning accuracy and prolongs both holder and insert life.
