S20R MDUNR boring bar — 93° geometry, MDUNR for DN-- 1104 (Teknik Makina)
A S20R MDUNR boring bar engineered for external boring with DN-- 1104 indexable inserts, offering a compact 20 mm shank and 50 mm cutting height for precision steel machining.
- 93° cutting geometry for stable boring
- Compatible with DN-- 1104 indexable inserts
- 20 mm shank for rigid machine mounting
- 50 mm cutting height for deep operations
Predictable chip flow and consistent bore quality
The 93° cutting geometry provides a neutral engagement that improves chip flow and reduces radial loads during external boring. When paired with DN-- 1104 indexable inserts, the toolholder produces repeatable bore finishes and minimises vibration, which translates into shorter cycle times and fewer rework passes. This geometry is particularly beneficial in production where consistency across batches is required; the result is improved process stability and a measurable uplift in productivity.
Rigid mounting for repeatable accuracy
A 20 mm shank combined with a 200 mm overall length gives a balance between reach and stiffness that suits many CNC turning and boring centres. The 50 mm cutting height supports deeper insert engagement without sacrificing clamping security, helping to maintain tool life and surface integrity. The compact design reduces overhang and optimises toolholder dynamics, which supports tighter tolerances and reduces the risk of chatter during demanding steel machining operations.
Versatile insert interface to streamline tooling
Designed specifically for the MDUNR insert pocket, compatibility with DN-- 1104 indexable inserts simplifies inventory and tool setup. The right-hand cutting direction is suitable for standard turning and boring cycles on most lathes and machining centres, and the indexable system enables fast insert changes, lowering downtime and enabling quick tool recovery between jobs. The result is fewer tooling variants on the shelf and more time producing finished components.
Built for workshop reliability and predictable production
With a compact weight of 0.508 kg and a 25 mm diameter body where relevant, the holder is sufficiently robust for high-use environments while remaining easy to handle during tool changes. The construction supports repeated clamping forces without loss of alignment, offering long-term stability in serial machining. For operations that demand dependable performance and straightforward insert management, this toolholder provides a pragmatic combination of durability and practical geometry.

Accessory Items
A compact, reliable solution for secure caliper fixation: the combination of an M5 thread and Ø 10 mm head delivers dependable clamping force, while the 26 mm overall length keeps the fastener unobtrusive in tight assemblies — order via Metav Werkzeuge or consult our specialists for product selection and supply. Locking screw by Teknik Makina — M5 thread, 26 mm overall length Locking screw for secure retention in measuring equipment and light workshop assemblies; designed for simple tightening with a 3 mm Allen key. M5 thread for standard fittings Ø 10 mm head for positive engagement 26 mm overall length for compact installation Requires 3 mm Allen key for assembly Reliable fixation for precision measuring instruments The fastener provides a consistent locking function that is particularly useful where repeatable position retention is required. With an M5 thread and a modest head diameter, the component achieves firm clamping without adding bulk. This makes it well suited to applications where space is limited but stability cannot be compromised. The technical simplicity of the design reduces maintenance needs and supports long-term serviceability in workshop environments. Quick installation and workshop compatibility Installation is straightforward thanks to the standard thread form and the compatibility with a common Allen key 3 mm. The combination of a small head (Ø 10 mm) and 26 mm length allows easy access even in confined setups, so adjustments can be made efficiently during measurement tasks or device servicing.
