Teknik Makina SIL S40T Boring Bar — Left-hand operation, Ø40 mm shaft, ER22 clamping

A robust SIL S40T boring bar from Teknik Makina engineered for left-hand machining with ER22 clamping; designed for use with 16–22ER indexable inserts in demanding workshop and industrial turning operations.

• Left-hand cutting direction
• Shaft Ø 40 mm, overall length 300 mm
• Compatible with 16–22ER indexable inserts
• ER22 clamping for secure insert fixation

Rigid design for steady cutting and repeatable results

The bar’s Ø40 mm shaft and 300 mm overall length are balanced to provide a rigid toolholding solution that limits vibration and deflection during heavy cuts. Rigid construction translates directly into consistent surface finish and prolonged insert life, as reduced chatter lowers edge wear. The relatively compact mass (approx. 2.842 kg) contributes to stable rotating dynamics while remaining manageable for standard tool posts and clamping systems. For production settings where cycle-to-cycle consistency matters, this geometry supports tighter tolerances and fewer reworks.

Quick tool changes and reliable insert compatibility

Designed specifically for indexable tooling, the bar accepts 16–22ER insert sizes and is secured by an ER22 clamping arrangement. The 60 mm cutting height gives adequate support for typical insert geometries used in roughing and finishing passes. The left-hand cutting orientation suits operations where a counter-rotation or specific tool path is required; left-hand tools cut when the tool moves contrary to the usual right-hand direction, enabling flexibility in lathe setups and part handling. This configuration reduces setup complexity by matching the bar to established insert standards and collet systems, enabling efficient changeovers and predictable cutting behaviour.

Practical benefits for the workshop and production line

A focus on tool-holding integrity and standard compatibility means fewer surprises at setup: secure clamping reduces the need for frequent retightening and lowers the probability of insert slippage under load. The bar’s ISO designation SIL S40T signals a recognised form factor that integrates with common holders and adaptors, simplifying inventory and procurement. Where cycle time and surface quality are priorities, using a dedicated indexable bar with aligned dimensions and clamping reduces downtime and supports continuous operation. For contractors and in-house workshops alike, this translates into measurable improvements in throughput and part quality.

Suitability and application notes

This tool is intended for indexable-insert turning and boring in conventional lathe environments where left-hand cutting is required. The combination of ER22 clamping and support for 16–22ER inserts makes it appropriate for a wide spectrum of steels and general-purpose turning tasks. The design emphasises mechanical stability and straightforward integration rather than specialised coolant or internal-feed features; for applications requiring internal coolant or unconventional geometries, consider verifying compatibility with the toolholder and machine setup before ordering.

FAQ

What insert sizes are supported by this boring bar?
The boring bar accepts 16–22ER indexable inserts; the ER22 clamping is specified to secure those insert sizes reliably in typical turning operations.

Is this tool suitable for right-hand and left-hand use?
This model is configured for left-hand cutting; for right-hand operations, select a corresponding right-hand variant rather than reversing usage.

Which clamping system is required for secure mounting?
The bar uses ER22 clamping; pairing with an ER22-compatible holder ensures correct fixation and repeatable tool positioning.

How does the shaft diameter affect machining stability?
A Ø40 mm shaft increases rigidity compared with smaller-diameter bars, reducing deflection under load and improving surface finish and tool life.
