Teknik Makina A16M SDQCR Boring Bar — Internal coolant, for DC-- 0702 indexable inserts

The A16M SDQCR boring bar is a compact external boring toolholder designed for CNC turning applications that accept DC-- 0702 indexable inserts, offering internal coolant and a right-hand cutting configuration

• A16M SDQCR design for indexable inserts
• Internal coolant for reliable chip evacuation
• 16 mm shank diameter, 150 mm overall length
• Compatible with DC-- 0702 indexable inserts

Enhanced stability and measurable surface benefits for turning operations

With a compact 16 mm shank and a balanced 150 mm overall length, the toolholder is engineered to reduce overhang and vibration. The 107.5° cutting angle provides a stable engagement geometry that spreads cutting forces and helps maintain consistent contact between insert and workpiece, which translates into a finer surface finish and longer tool life. Because rigidity directly affects repeatability, the reduced deflection of the assembly is reflected in improved dimensional accuracy during serial production runs. These mechanical advantages are particularly relevant when machining medium-duty components where productive cycle time and repeatable tolerances are required.

Targeted coolant flow and chip control to protect inserts and increase uptime

Equipped with internal coolant, the bar supplies cooling fluid directly to the cutting zone, which lowers thermal load on the insert and encourages efficient chip control. That focused lubrication reduces built-up edge and thermal wear, so insert changes become less frequent and process stability improves. The right-hand cutting orientation supports standard turning setups and predictable chip flow. For operations where heat and chip evacuation are critical — such as interrupted cuts or higher spindle speeds — the internal coolant feature is a practical performance enhancer that reduces scrap risk and contributes to continuous production.

Compatibility that simplifies toolroom logistics and integration

Designed for use with DC-- 0702 indexable inserts, the holder streamlines tooling choices and allows for straightforward stocking of common insert grades. The tool’s modest mass (0.232 kg) helps minimise imbalance in high-speed spindles and simplifies dynamic balancing where required. The shank and clamping geometry are compatible with standard toolposts and turret adapters, so retrofit into existing setups is uncomplicated. Sourcing through Metav provides a dependable supply chain and technical filtering at the distribution hub in Emmerich, ensuring that procurement for workshops and small production facilities is backed by consistent quality assurance.

FAQ

Which inserts fit this boring bar?
The A16M SDQCR boring bar is specified for DC-- 0702 indexable inserts; Teknik Cutting Tools’ holder and those inserts form the intended combination for correct seating and chip control (SKU KA143TM).

Does the bar provide coolant to the cutting edge?
Yes — internal coolant is integrated and channels fluid to the cutting zone to improve cooling and chip control, which helps extend insert life.

What are the main dimensions to check for machine compatibility?
Key dimensions are the 16 mm shank diameter and 150 mm overall length; confirm these against the machine tool’s toolpost and turret capacity before fitting.

Is the cutting direction right- or left-handed?
The configuration is right-handed, suitable for standard turning operations with conventional toolholding orientation.

How does the 107.5° cutting angle affect machining?
The 107.5° cutting angle distributes cutting forces to improve stability and reduce vibration, which typically results in better surface finish and less insert wear.
