20 mm Boring Bar for CCMT 0903 Indexable Inserts – 150 mm, S16M (Teknik Makina)

The 20 mm boring bar is a compact toolholder intended for precision internal turning with CCMT 0903 indexable inserts, offering a secure S16M shank and a short 150 mm overall length for confined setups

• Compatible with CCMT 0903 indexable inserts
• Solid S16M shank for secure clamping
• 20 mm diameter with 150 mm overall length
• Right-hand 95° cutting geometry

High-impact stability and repeatable bore quality

The boring bar is engineered to support consistent, low-vibration performance in internal turning tasks. Its S16M shank provides a rigid connection to the machine spindle, which reduces chatter and improves surface finish; this stability is particularly relevant when using CCMT 0903 indexable inserts, as the insert geometry benefits from a firm toolholder. A 20 mm diameter body combined with a 150 mm overall length balances access to internal bores with torsional stiffness, enabling reliable material removal rates and fewer rejected parts. For production environments where cycle-time and repeatability matter, the component's compact design helps maintain throughput without sacrificing precision.

Fast insert changes and straightforward upkeep

Tool change and maintenance are simplified by standardised fastenings: the clamping screw specified is M3.5x8.5, tightened using a Torx T15 key. This familiar interface allows rapid index changes of CCMT 0903 inserts and straightforward torque application, reducing machine downtime. The toolholder’s right-hand cutting orientation and 95° cutting angle are clear, established parameters that allow workshop planners to predict cutting forces and select compatible inserts or adapt cutting data. The combination of clear mechanical interfaces and documented fastening makes inventory management and staff training more efficient while lowering the risk of incorrect assembly.

Compact design tailored to machine-room realities

A short overall length and controlled mass make this boring bar well suited to confined setups where tool overhang must be minimised. The product’s klemmhalter scheidkopf width 11 mm (clamping head width) and shaft diameter 16 mm contribute to compatible mounting and allow secure clamping in many common toolposts. With a measured weight of 0.228 kg, the holder introduces minimal centrifugal load at moderate speeds while remaining robust enough for stable cutting. Produced by Teknik Makina, the component is intended as a pragmatic option for workshops and production lines seeking a compact, indexable-insert solution that integrates with standard tooling systems.

FAQ

Which inserts fit this boring bar?
The K109TM boring bar is designed for CCMT 0903 indexable inserts and accepts those inserts in the standard CCMT 0903 format.

What is the shank specification for mounting?
Mounting requires a toolholder compatible with an S16M shank; the K109TM uses that shank form for secure clamping.

Is the cutting orientation right- or left-hand?
This toolholder is configured for right-hand cutting with a 95° cutting geometry.

What fastener and key are used for the insert?
Insert retention uses an M3.5x8.5 screw tightened with a Torx T15 key.
