Klemmhalter D307-2TM — DCLN toolholder for CN-- indexable inserts, left-hand, 95°

The Klemmhalter D307-2TM is a left-hand DCLN toolholder engineered for metalturning applications with CN--1906 indexable inserts and a robust 95° cutting geometry.

• Left-hand orientation for turning tasks
• Compatible with CN--1906 inserts
• Robust 40 mm head and shank dimensions
• 95° cutting angle for stable cuts

Stable clamping for consistent turning results

A rigid clamping arrangement is central to repeatable machining, and this toolholder provides a stable interface between machine and insert. With a head and shank width of 40 mm and a cutting height of 40 mm, the design reduces vibration and supports steady chip formation; the mass of 3.195 kg contributes to dampening during heavy cuts. Reduced chatter improves surface finish and extends the life of both the insert and the holder, so cycle times remain predictable and tool-change intervals become easier to plan. The solid geometry is particularly beneficial where dimensional consistency across batches is required.

Precision compatibility that simplifies tooling choices

Designed for DCLN-style holders and to accept CN--1906 indexable inserts, the product—identified under DCLNL 4040—matches common industry insert grades and shapes. The 95° cutting angle is optimised for conventional turning operations, offering a balance between approach angle and clearance that helps maintain stable cutting forces. The left-hand orientation suits applications where the tool must cut counter to right-hand holders; this is indicated as left-hand in the specification and should be selected where the process or machine setup demands it. The shank designation S19 clarifies the holder interface for fixture planning and compatibility checks.

Practical dimensions and workshop integration

With an overall length of 250 mm, the holder fits standard turret and toolpost arrangements while keeping the centre of cutting action accessible for inspection and measurement. The consistent 40 mm shank and head dimensions simplify fixture planning and stock management, as like-for-like holders reduce the variety of spares required. The compatibility with established indexable inserts means inserts can be stocked across multiple holders, lowering logistical overhead. Clear, measurable specifications support rapid selection in engineering documentation and facilitate process validation in production environments.

FAQ

What insert type fits this holder?
The holder accepts CN--1906 indexable inserts; the designation DCLN indicates compatibility with this insert family for standard turning tasks.

Is the holder suitable for right-hand turning?
The D307-2TM is specified as left-hand; for right-hand operations a mirror-design holder should be chosen.

What does the 95° cutting angle mean for machining?
A 95° cutting angle provides a robust approach angle that balances cutting force direction and insert clearance, which supports stable chip control and consistent surface finish.

How do the holder dimensions affect turret setup?
Consistent 40 mm head and shank widths simplify turret planning and reduce the need for multiple adapter sizes, aiding quicker setup and repeatable positioning.

Can this holder be used across different insert grades?
Compatibility is with the CN--1906 form; different grades (coatings or substrate) of the same insert geometry can be used for varied materials or cutting conditions.
