20mm Boring Bar for VBMT 1103 Indexable Inserts 180mm, Internal Coolant - Teknik Makina

The combination of a 20 mm diameter, internal coolant and a 180 mm overall length ensures steady chip evacuation and controlled heat dissipation for consistent boring performance; order the tool directly via Metav Werkzeuge or request advice from our consultants.

Boring bar for VBMT 1103 indexable inserts — 20 mm, internal coolant (Teknik Makina)

A Boring bar engineered for VBMT 1103 indexable inserts, providing left-hand cutting capability and internal coolant for improved process stability.

• 20 mm bar diameter, compatible with VBMT 1103
• Internal coolant for improved chip flow
• 180 mm overall length for deeper bores
• Left-hand cutting, 93° cutting angle

Accurate insert seating for consistent turning results

The tool is designed to accept VBMT 1103 indexable inserts with a secure clamping interface that maintains repeatable positioning under load. With a 93° cutting angle and a cutting height of 30 mm, the configuration reduces radial forces and contributes to steady deflection behaviour in light- to medium-duty operations. The clamping screw specification M2.5x6.5 (Torx T8) ensures a compact and secure fixation; the small, precise fastener reduces the risk of micro-movements that would otherwise affect surface finish. Clear technical match between insert geometry and holder geometry translates into fewer regrinds and more consistent batch-to-batch quality.

Built for coolant-assisted deep boring and thermal control

Internal coolant routing is a primary performance advantage: the integrated coolant channel directs fluid to the cutting zone for effective heat removal and chip breaking, which extends insert life and stabilises cutting forces. The combination of a 20 mm cutting diameter and 180 mm overall length allows deeper reach while the 16 mm shank diameter provides a compact clamping footprint in many tool posts. The tool's modest mass (0.278 kg) helps reduce centrifugal loads in high-speed turning and contributes to dynamic balance. Together, these features support efficient cycle times and reduced downtime for insert changes.

Workshop compatibility and straightforward maintenance

Engineered for industrial and specialist turning environments, the bar fits standard clamping systems and is appropriate for CNC turning centres and toolroom lathes performing left-hand cuts. Material and application data support machining of a broad range of workpiece materials when paired with the correct insert grade and cutting data. Routine maintenance is simplified by the standard Torx T8 access and common screw size, enabling quick insert swaps and secure reassembly. The nominal ISO designation A16Q and the product SKU KA282TM assist in procurement and inventory control for production planners and buyers.

FAQ

What insert type is compatible with this boring bar?
The boring bar accepts VBMT 1103 indexable inserts and is configured to provide correct seating and clearance for that insert geometry.

Is the coolant fed internally or externally for this tool?
This holder features internal coolant, which supplies fluid directly to the cutting edge to improve chip control and thermal management.

Which cutting direction is intended for the bar?
The bar is manufactured for left-hand cutting operations with a 93° cutting angle suitable for standard left-hand turning setups.

What are the key dimensions to check for machine compatibility?
Relevant dimensions include a 20 mm cutting diameter, 180 mm overall length and 16 mm shank diameter; these should be matched to the machine's tool post and clearance envelope.

What fastener and tool are required for insert clamping?
Insert clamping uses a Torx M2.5x6.5 screw tightened with a T8 Torx key, offering compact and reliable fixation.
