K337-2TM boring bar – 7.8 mm cutting diameter, 16 mm shank (Teknik Makina)

The K337-2TM is a right-hand boring bar designed for internal turning with an SIR holder for IR indexable inserts, suitable for precision finishing and tight-reach operations

• Right-hand cutting direction
• Compatible with IR08 indexable inserts
• 16 mm shank for secure clamping
• 125 mm overall length for deep reach

High-precision internal finishing with rigid support

The combination of a 7.8 mm cutting diameter and 18 mm cutting height makes this boring bar a compact solution for accurate internal machining. The SIR holder specification (SIR S16K) and compatibility with IR08 indexable inserts ensure repeatable seating and predictable chip formation, which supports consistent bore quality over series production. With a 16 mm shank, the component offers improved resistance to deflection compared with smaller shanks, resulting in steadier cuts and reduced need for rework. These attributes translate into measurable process advantages for workshop operations that prioritise dimensional accuracy and surface finish.

Fast insert changes and dependable clamping system

Maintenance of cutting capability is simplified by a Torx-secured fastening system that uses a Torx T6 key and an M2x4.6 screw. This arrangement supports rapid indexable insert replacement and secure locking of the cutter, promoting short set-up times and reliable repeatability during shift work. The boring bar’s modest mass (0.195 kg) reduces inertia during rapid tool changes while remaining substantial enough to contribute to stable clamping during cut entry. The result is increased uptime and lower non-productive time for machining cells where quick tool swaps are routine.

Practical advantages for small-bore and precision workshops

With an overall length of 125 mm and a compact profile, the tool is engineered for confined spaces and internal operations on CNC lathes and turning centres. The right-hand cutting orientation and SIR holder system are well matched to finishing passes and light to medium internal turning, providing a balance between accessibility and cutting capacity. The K337-2TM’s specification supports modular tooling strategies: it integrates with existing SIR setups and IR insert stocks, enabling straightforward tool standardisation on the shop floor. Combined with consistent component labelling and dependable delivery from Metav Werkzeuge, this boring bar aids process standardisation and inventory rationalisation.
