K207TM Boring Bar by Teknik Makina — 20 mm shank, 180 mm overall length

The K207TM Boring Bar is a right-hand SVUB holder engineered for VBMT 1103 indexable inserts, optimised for stable internal turning and finishing operations in CNC setups.

• Right-hand cutting for clean internal turning
• Compatible with VBMT 1103 indexable inserts
• 20 mm shank for stable clamping in holders
• 180 mm overall length for deep reach

Built for rigidity and repeatable bore quality

A compact holder with a 20 mm shank and a 25 mm diameter body provides measurable stiffness, which reduces vibration and improves surface finish. The combination of a tight shank fit and a defined cutting angle of 93° means that axial and radial loads are better absorbed; as a result, bore concentricity and repeatability are improved. This stability translates into fewer scrap parts and less rework, a rational advantage when process reliability is top priority.

Fast insert changes and clear compatibility

The tool is specified for VBMT 1103 indexable inserts and carries the ISO designation S20Q SVUBR, indicating the SVUB-style pocket geometry for those inserts. Indexable inserts offer quick replacement and consistent edge geometry without full regrinding, so tool-change downtime is minimised. The holder accepts the standard clamp designation 11, allowing straightforward integration into common clamping systems and reducing setup complexity in the workshop.

Practical workshop benefits and process fit

Designed as a right-hand tool for internal turning, the boring bar balances reach and stiffness with its 180 mm overall length and modest mass of 0.7 kg, making it suitable for medium-depth bores where access and stability must be balanced. The SVUB pocket design maintains secure engagement of the insert, so stable clamping and predictable cutting behaviour are achieved. For production environments seeking consistent cycle times, the holder’s geometry supports reproducible cuts and efficient tool life management.

FAQ

Which inserts are compatible with this boring bar?
The K207TM boring bar is compatible with VBMT 1103 indexable inserts and is specified for SVUB pocket geometry.

What is the shank diameter and why does it matter?
The shank diameter is 20 mm; a thicker shank increases rigidity and reduces vibration, which improves bore accuracy and surface finish.

Is the tool configured for right- or left-hand cutting?
This holder is set up for right-hand cutting, suitable for standard internal turning directions on most lathes and CNC machines.

What is the ISO designation of the holder?
The tool carries the ISO designation S20Q SVUBR, which defines the shank form and the SVUB-style insert pocket.

What are the overall length and weight of the tool?
The overall length is 180 mm and the weight is approximately 0.7 kg, offering a balance between reach and stiffness for medium-depth bores.
