KA319TM boring bar – 20 mm diameter, internal coolant (A16Q SVQCL) | Teknik Makina

The KA319TM boring bar is engineered for internal turning with VCMT 1103 indexable inserts, offering through‑coolant capability and a standard ISO A16Q SVQCL shank for stable mounting in CNC toolholders

• Internal coolant for effective chip evacuation
• Compatible with VCMT 1103 indexable inserts
• ISO A16Q SVQCL for standardised mounting
• Torx M2.5x6.5 clamp with T8 key

Higher throughput and consistent finish through internal coolant

The KA319TM is built to improve cycle reliability in internal turning operations by integrating a through‑coolant channel that directs cutting fluid closely to the cutting edge. This feature reduces tool temperature, supports consistent chip breaking and lowers the risk of thermal distortion, which in turn helps to maintain a repeatable surface finish and prolong insert life. The 20 mm diameter and 180 mm overall length provide a balanced reach for many common boring tasks without unnecessarily stressing the spindle, while the ISO A16Q SVQCL designation ensures compatibility with standard clamping systems used in workshop spindle noses and turret adapters.

Secure clamping and rapid indexable‑insert changes

Clamping integrity is central to predictable machining results; the holder employs a Torx M2.5x6.5 screw and is designed for tightening with a T8 key, giving a compact and reliable fixation for VCMT 1103 inserts. The compact screw design allows for quick insert replacement and stable seat contact, reducing downtime during shift changes. At approximately 0.271 kg, the assembly keeps inertia low for dynamic runs while still providing sufficient mass to dampen chatter in moderate cutting conditions. For less experienced users, indexable inserts are hardened, pre‑ground cutting tips that can be rotated or replaced without regrinding, offering repeatable geometry and predictable tool life.

Practical workshop integration and suitable applications

This boring bar is suitable for internal finishing and semi‑finishing tasks where indexable carbide inserts are preferred for productivity and cost control. The combination of standard ISO shank dimensions and coolant supply makes the holder adaptable to many CNC lathes and machining centres that accept A16Q‑type tooling. Where surface integrity and tool life are priorities, the internal coolant option reduces heat at the cutting zone and helps evacuate chips from confined bores. For selection, pairing the holder with the appropriate grade of VCMT 1103 inserts ensures the best balance between wear resistance and toughness for the machined material.

FAQ

Which insert type fits this holder?
The KA319TM boring bar is designed for VCMT 1103 indexable inserts; pairing with the recommended insert geometry ensures correct seating and chip control.

Does the holder provide through‑coolant functionality?
Yes, this holder features internal coolant to feed cutting fluid directly to the insert edge, improving cooling and chip evacuation during internal machining.

What is the ISO designation and why does it matter?
The tool carries the A16Q SVQCL ISO designation, which defines the shank interface and ensures compatibility with standard A16 clamping fixtures in many CNC toolposts.

Which fastening hardware is used for the insert?
Insert clamping is achieved with a Torx M2.5x6.5 screw tightened using a T8 key for secure and repeatable insert retention.

Is the KA319TM suitable for long‑reach boring operations?
With an overall length of 180 mm and a 20 mm shank, the holder is aimed at common internal turning tasks; extremely long‑reach operations may require alternative geometries to control deflection.
