S16Q SDXCR boring bar by Teknik Makina — 16 mm shank, for DC-- 11T3 inserts

The S16Q SDXCR boring bar is a right-hand internal turning tool designed for use with DC-- 11T3 indexable inserts, offering a compact 16 mm shank and 180 mm overall length for versatile workshop and production use

• S16Q SDXCR boring bar for DC-- 11T3 inserts
• 16 mm shank for compact toolholders
• 180 mm overall length for extended reach
• Right-hand cut; 120° cutting edge angle

Improved process stability through a compact, rigid design

The S16Q SDXCR is built around a 16 mm shank, which increases torsional stiffness compared with smaller profiles; this rigidity translates into reduced vibration and more consistent bore geometry when performing internal turning operations. For shops aiming for repeatable tolerances, the compact shank reduces deflection during light to medium-depth cuts, improving surface finish and runout control without the need for oversized toolholders. The specification of 180 mm overall length offers an economical reach for many common internal machining tasks while limiting the lever arm that causes chatter.

Fast tooling change and lower operating costs with indexable inserts

Compatibility with DC-- 11T3 indexable inserts means cutting edges can be renewed in seconds, keeping machine downtime to a minimum. Indexable inserts separate the expensive cutting edge from the bar body; when the edge wears, only the insert is replaced, which reduces long-term tooling expenditure. The SDXCR geometry is optimised for secure clamping of the insert, supporting consistent cutting results and straightforward re-indexing for repeated cuts or batch production.

Predictable chip control and cutting behaviour for right-hand turning

The tool features a 120° cutting angle and a right-hand cutting direction, a combination that promotes stable chip formation and predictable cutting forces for typical internal turning motions. The defined edge geometry assists in directing swarf away from the cutting zone, which is especially useful in confined bores. For machinists less familiar with insert tooling: the cutting angle is the angle formed at the insert edge that affects how the chip is sheared off and how the tool engages the workpiece; a 120° angle is commonly selected to balance strength and chip flow.

Practical dimensions and lightweight construction for flexible set-up

With an external diameter of 20 mm and a mass of 0.285 kg, the bar is light to handle during tool changes yet substantial enough in cross-section to contribute to a rigid assembly. The 40 mm cutting height is indicated for correct seat engagement of the insert, ensuring the insert sits at the intended centreline relative to the toolholder. These measurable values allow purchasing and set-up decisions to be made quickly and with confidence when integrating the bar into existing holders or modular tooling systems.

FAQ

Which inserts fit this boring bar?
The bar accepts DC-- 11T3 indexable inserts; the geometry and clamping are matched to the SDXCR insert family for stable seating and repeatable positioning (S16Q SDXCR, K471TM).

Is the cutting direction right-hand or left-hand?
This model is specified for right-hand cutting; machining operations should be planned accordingly to match spindle rotation and feed direction with the S16Q SDXCR bar.

What are the key dimensions to check for holder compatibility?
Check the 16 mm shank diameter, 180 mm overall length and 20 mm outer diameter against the toolholder bore and clamping limits before mounting the S16Q SDXCR.

How does the 120° cutting angle affect machining?
A 120° cutting edge angle balances edge strength with chip formation, resulting in reliable cutting forces and predictable chip flow when using the SDXCR insert geometry.

Can the S16Q SDXCR be used for heavy roughing cuts?
The bar’s compact 16 mm shank and specified geometry are optimised for precision internal turning and intermediate cuts; for heavy roughing, consider a larger-shank bar or specialist roughing tooling to preserve stability.
