Precision turning benefits from internal coolant and secure clamping for DC-- 0702 indexable inserts, while the left-hand orientation suits specialised turning tasks; order the KA270TM via Metav Werkzeuge or consult our product advisers for tailored application support.

KA270TM Boring Bar (A10J SDQCL) by Teknik Makina — Left-hand, internal coolant

A KA270TM boring bar designed for turning operations with DC-- 0702 indexable inserts, providing coolant-fed chip control and a compact footprint for CNC lathes

• A10J SDQCL ISO designation
• Internal coolant for improved chip evacuation
• Compatible with DC-- 0702 indexable inserts
• Left-hand cutting, 12 mm cutting diameter

Greater process reliability through coolant-fed chip control

The internal coolant channel delivers cutting fluid directly to the insert edge, markedly improving chip evacuation and reducing thermal load at the cutting zone. This direct feed helps maintain tool life under continuous operation and lowers the risk of built-up edge formation. For workshop environments where cycle time and repeatability matter, the coolant feature supports stable cutting forces and fewer unscheduled tool changes, contributing to predictable machining output.

Fast setup and repeatable clamping for indexable inserts

Designed around the DC-- 0702 insert family, the toolholder carries the A10J SDQCL ISO designation and accepts the defined clamping system 07, enabling rapid insert changes and consistent seating. The cutting angle 107.5° and a 20 mm effective cutting height are matched to the insert geometry, so setting and re-establishing cutting parameters is straightforward. These characteristics reduce setup time and improve process repeatability, which is essential for batch production or finishing passes on turned components.

Compact design for precision and minimal vibration in confined workspaces

Small-diameter construction with a 12 mm cutting diameter, 10 mm shaft diameter and 110 mm overall length keeps overhang to a minimum, lowering bending and chatter during fine turning; the tool weighs 0.074 kg, aiding rapid spindle acceleration and dynamic stability. The left-hand cutting orientation broadens suitability for specific turning sequences and fixtures on CNC lathes. The KA270TM presents a compact, performance-oriented solution where precision, rigidity and reliable insert support are required.

FAQ

What inserts fit this boring bar?
The KA270TM boring bar is compatible with DC-- 0702 indexable inserts and is designed to accept the matching clamping system for secure retention.

Does the tool support internal coolant?
Yes, the KA270TM features internal coolant to supply cutting fluid directly to the insert edge, improving chip evacuation and thermal control.

Is this tool suitable for confined or small-diameter turning?
With a 12 mm cutting diameter and 110 mm overall length, the KA270TM is engineered to minimise overhang and reduce vibration in compact turning operations.

What is the cutting orientation of the bar?
The bar is configured for left-hand cutting, making it appropriate for machining sequences that require that orientation on a lathe.

Which ISO designation applies to the toolholder?
The toolholder is specified as A10J SDQCL, reflecting its design for SDQC-style indexable-insert applications.
