Boring bar S16M for DC-- 11T3 indexable inserts — Teknik Makina

The boring bar S16M is a purpose-designed tool for internal turning with DC-- 11T3 indexable inserts, offering stable rigidity and compatibility for workshop and CNC lathe applications

• 20 mm diameter for compact bores
• Compatible with DC-- 11T3 inserts
• Left-hand cutting orientation
• 16 mm shank for secure clamping

Precision and stability for internal machining

The S16M boring bar provides consistent bore geometry through a 20 mm body that balances rigidity and access in confined spaces. A firm 16 mm shank reduces vibration at higher spindle speeds, which translates into improved surface finish and longer insert life. For users unfamiliar with the term, shank diameter refers to the portion clamped in the tool holder; a larger, well-matched shank minimises deflection and helps maintain tolerance chains during production.

Secure insert mounting and easy serviceability

Compatibility with DC-- 11T3 indexable inserts ensures a widely available range of cutting grades and geometries for different materials. The insert is fixed by a Torx T15 fastening system using an M3.5x8.5 screw, which provides repeatable clamping force and straightforward replacement. This arrangement reduces downtime: individual inserts can be rotated or exchanged without dismantling the entire tool, supporting efficient shop-floor workflows.

Optimised for left-hand cutting operations

Designed for left-hand cutting, this boring bar suits setups requiring counter-directional tool travel, for example when machining features on certain lathe configurations or when specific chip flow is required. The 107.5° cutting angle is selected to balance cutting forces and edge strength, offering predictable material removal and helping to avoid chatter when paired with an appropriate holder and stable workholding.

Practical design for workshop integration

With an overall length of L150 mm and a compact mass of 0.312 kg, the tool is easy to handle and integrates well into standard tool inventories. The S16M designation signals the shank interface and assists purchasing and inventory management. For workshops seeking to standardise tooling across machines, this boring bar supports a pragmatic combination of accessibility, repeatability and serviceability.

FAQ

What insert type fits this boring bar?
The S16M boring bar is designed for DC-- 11T3 indexable inserts, enabling use of standard insert grades and geometries for a range of materials.

Is the cutting orientation suitable for my lathe?
This tool features left-hand cutting, so it is appropriate where counter-directional tool travel is required; check the machine tool setup before use.

Which fastener secures the insert?
Insert clamping uses a Torx T15 interface with an M3.5x8.5 screw for reliable, repeatable fixation.

How does the shank size affect performance?
The 16 mm shank offers improved rigidity within compatible holders, reducing deflection and improving surface finish on internal bores.

Can this boring bar be used for small-diameter bores?
With a 20 mm diameter, the tool is suitable for compact bores where a balance of access and stiffness is required; select holder and speeds accordingly for best results.
