S16Q SDUCL boring bar — left-hand, for DC-- 0702 indexable inserts (Teknik Makina)

The S16Q SDUCL is a left-hand boring bar intended for internal turning where stability and predictable insert engagement are required, compatible with SDUC-style indexable inserts for DC-- 0702 applications.

• Left-hand cutting direction
• Compatible with DC-- 0702 inserts
• 20 mm outer diameter, 180 mm overall length
• 16 mm shank, 30 mm cutting height

Stable performance for internal turning with reduced vibration

The boring bar is engineered to deliver a steady cutting action in confined bores: the left-hand cutting geometry and cutting angle 93° are tuned to reduce chatter and concentrate cutting forces closer to the support zone. This results in improved surface finish and more consistent diameters when compared with less rigid setups. Where stability is prioritised, the designed cutting geometry supports higher metal-removal rates without sacrificing finish, making the bar suitable for production and jobbing environments that require repeatable results.

Efficient insert system that reduces downtime

Designed for use with SDUC style indexable inserts, specifically the DC-- 0702 format, the toolholder permits rapid insert changes while maintaining secure seating. Indexable inserts are rotated or replaced when a cutting edge is worn, which cuts tool-change time and lowers consumable cost per part relative to single-point tooling. Spare-edge economics and straightforward replacement contribute to predictable process costs and simplified toolroom logistics, particularly when multiple bores or varying cutting passes are scheduled.

Workshop-ready dimensions for straightforward integration

Key dimensions are provided to aid machine setup and fixturing: 16 mm shank, 20 mm outer diameter and 180 mm overall length give a compact, balanced profile that suits many turret and boring-bar spindles. The 30 mm cutting height aligns the insert position for common clamping arrangements and ensures consistent chip flow. With a listed weight of 0.292 kg, the bar is light enough for rapid index changes but robust enough to sustain finish-critical passes. These specifications were chosen to enable reliable mounting, quick alignment and predictable thermal behaviour across extended runs.

FAQ

Which insert type fits this boring bar?
The tool is specified for SDUC style indexable inserts and listed for DC-- 0702 inserts; these insert types are compatible with the clamping geometry of the bar.

Is the bar suitable for right-hand machining?
The bar is configured for left-hand cutting; for right-hand operations a corresponding right-hand toolholder should be selected.

What are the key dimensions to check before purchase?
Verify the 16 mm shank, 20 mm outer diameter and 180 mm overall length against the machine turret or spindle allowance to ensure correct mounting and clearance.

Can this boring bar be used on CNC lathes and toolposts?
The compact dimensions and ISO designation make the bar appropriate for many CNC turret and toolpost arrangements when the machine accepts a 16 mm shank and left-hand cutting is required.

What is the SKU and who is the manufacturer?
The SKU is K256TM and the manufacturer is Teknik Cutting Tools (Teknik Makina); the tool is marketed and distributed via Metav Werkzeuge.
