Boring bar SIL S40T by Teknik Cutting Tools — 40 mm shank, left‑hand

A SIL S40T boring bar designed for left‑hand internal turning with 16 ER indexable inserts, suitable for CNC lathes and precision workshop applications

• SIL S40T design for 16 ER inserts
• 40 mm shank for rigid clamping
• 60 mm cutting height for deep cuts
• Left‑hand cutting direction

Stable clamping for improved surface finish and tool life

The combination of a 40 mm shank and a robust construction delivers reduced vibration and greater rigidity during internal turning, which directly benefits surface finish and cutter life. With a 300 mm overall length and a mass of 2.839 kg, this tool balances reach and stability for medium‑depth boring operations. Operators and process planners will notice fewer reworks and more consistent cycle times when a rigid bar is used instead of undersized alternatives.

Fast insert changes and predictable cutting performance

Engineered specifically for 16 ER indexable inserts, the SIL geometry simplifies insert seating and repeatability, shortening downtime at tool change. The 60 mm cutting height provides a deep, secure insert pocket for heavy cuts and chip control, enabling efficient material removal rates without compromising safety. This configuration supports standard ER16 clamping arrangements and integrates smoothly into existing toolholding systems.

Left‑hand orientation for tailored turning strategies

A left‑hand cutting direction suits specific machining setups and complements toolpaths where reverse orientation improves chip flow or access. The left feed orientation, combined with the tool’s geometry, allows reliable engagement in internal boring tasks on CNC lathes and turning centres. The design is particularly useful when machining features that require a left‑hand approach to meet fixture or lathe‑axis constraints.

FAQ

Which indexable inserts fit this tool?
The SIL S40T boring bar from Teknik Cutting Tools is specified for 16 ER indexable inserts and is designed to accommodate the seating and clamping geometry typical for that size.

What are the key mounting dimensions?
Relevant dimensions are a 40 mm shank diameter, 45 mm diameter, 300 mm overall length and 60 mm cutting height, which determine clamping and reach requirements for the machine setup.

Is the cutting direction important for setup?
Yes; the tool is manufactured for left‑hand cutting and should be used in operations and toolpaths that call for left‑hand engagement to ensure correct chip evacuation and cutting forces.

Which toolholders are compatible?
The bar is compatible with ER16 clamping systems and integrates into standard ER16 collet holders and corresponding tool posts on lathes and machining centres.

Can the tool be used on CNC lathes for medium‑duty production?
Yes; the SIL S40T boring bar is built for CNC and lathe internal turning in production environments where a rigid shank and reliable insert seating are required.
