K286TM boring bar — SVUB for VBMT indexable inserts, left-hand, 25 mm shank (Teknik Makina)

The K286TM boring bar is a left-hand turning holder designed for VBMT 1604 indexable inserts, offering a compact 200 mm overall length for tight lathe setups.

• Left-hand cutting orientation
• Fits VBMT 1604 indexable inserts
• 25 mm shank diameter for rigidity
• ISO S25R SVUBL designation

Precision and rigidity for improved surface finish

The robust 25 mm shank and 32 mm body diameter combine to deliver structural stability under load, reducing vibration and chatter in demanding turning tasks. With a measured mass of 0.73 kg, the holder balances stiffness and manoeuvrability, making it suitable for medium-duty external operations where consistent form and surface integrity are required. The modest overall length of 200 mm supports access into confined work zones while keeping the tool overhang low, which directly contributes to longer insert life and more predictable cutting performance.

Seamless compatibility with VBMT 1604 indexable inserts

Designed specifically for VBMT 1604 inserts, the SVUB-style seat and a cutting height of 40 mm ensure correct insert alignment and positive clamping. The ISO designation S25R SVUBL identifies the shank geometry and left-hand orientation, allowing straightforward integration into existing tool setups. Indexable inserts permit rapid replacement and reindexing, which reduces downtime and simplifies inventory management compared with brazed or solid tools. Where insert indexing is required, this holder supports efficient changeover and consistent cutting geometry.

Left-hand orientation and cutting angle tuned for turning tasks

A cutting direction set to left-hand and a nominal cutting angle of 93° position the geometry for common turning profiles and facing operations on lathes configured for left-hand approaches. The design suits workshops that require tools for specific spindle directions or for operations where access dictates left-hand tooling. The result is a reliable toolholder that offers both predictable chip flow and secure insert retention, minimising the need for frequent adjustments and supporting steady cycle times in production environments.

FAQ

Which inserts are compatible with this holder?
The K286TM boring bar is compatible with VBMT 1604 indexable inserts; the seat and cutting height are matched to that insert type to ensure correct geometry.

Is the tool suitable for left-hand spindle operations?
Yes, the holder is configured for left-hand cutting direction and is intended for use in applications requiring left-hand tooling.

What does the ISO designation S25R SVUBL indicate?
The ISO code S25R SVUBL identifies the shank geometry (25 mm shank) and the SVUB left-hand configuration used by this type of indexable insert holder.

How does the 25 mm shank affect performance?
A 25 mm shank diameter increases rigidity compared with slimmer holders, reducing overhang-induced vibration and improving surface finish and insert life.

Is this holder suitable for confined lathe setups?
With an overall length of 200 mm, the K286TM offers a compact footprint for tighter workspaces while maintaining sufficient reach for standard turning tasks.
