Boring bar S20R – compact right-hand tool with Ø20 mm shank (Teknik Makina)

A boring bar S20R engineered for precise internal turning and insert clamping, suitable for compact setups where rigidity and accurate tool positioning are essential

• Ø20 mm shank for rigid mounting
• Overall length 200 mm for short overhangs
• Right-hand cutting for standard machining
• Torx T15 clamp screw M3.5x8.5

High rigidity for consistent bore quality

The stiff Ø20 mm shank and a short 200 mm overall length reduce deflection during internal machining, which translates into smaller tolerances and more consistent bore diameters. Reduced vibration improves surface finish and extends insert life, so fewer interventions are required during production runs. This makes the tool a reliable choice for small- to medium‑batch work where dimensional stability is essential.

Secure clamping for fast, repeatable index changes

Equipped with a Torx T15 clamping interface and M3.5x8.5 fastening screw, the holder ensures repeatable seating of the insert carrier and quick changes. The 15 mm clamping width provides a secure contact area between the clamping head and the tool body, reducing the likelihood of micro‑movement under cutting forces. Clear mechanical interfaces shorten downtime and simplify tool management on the shop floor.

Machining geometry tuned for efficient metal removal

The tool’s 3° cutting angle and 25 mm effective cutting edge height support stable metal removal with predictable chip flow in right‑hand operations. These geometric parameters are chosen to balance cutting forces and tool life, enabling efficient feed rates while maintaining surface integrity. For operators unfamiliar with the term, cutting angle describes the orientation of the cutting edge relative to the workpiece and directly affects cutting load and finish quality.

Practical advantages for workshop integration

Lightweight at 0.43 kg, the bar is straightforward to handle during set-up and reduces operator fatigue when mounting multiple holders. The compact profile fits tight bores and minimises overhang, lowering the risk of chatter in confined operations. Supplied as a labelled item (SKU K201TM) from Teknik Makina, the design is intended to integrate smoothly into established tool inventories and stock systems.

FAQ

What materials is this boring bar suited for? The boring bar S20R (Teknik Makina, SKU K201TM) is intended as a general-purpose holder; material suitability depends on the chosen insert and cutting parameters rather than the holder itself

How is the insert clamped and secured? Clamping is achieved via a Torx T15 screw (M3.5x8.5), which secures the clamping head to the tool body for repeatable seating

Can the tool be used for long‑reach boring operations? The 200 mm overall length and Ø20 mm shank are optimised for short to medium overhangs; for long‑reach applications a larger shank and longer‑reach holder would be recommended

Which cutting direction does the holder support? This holder is configured for right‑hand cutting, suitable for standard turning and internal boring orientations

Is the product identified for stock control? Yes, the tool is supplied with SKU K201TM and the label "20mm Bohrstange L200mm" for straightforward inventory management
