KA188TM Boring bar (A25R STFCL) – STFC holder for TCMT indexable inserts, left-hand, internal coolant by Teknik Makina

The KA188TM is a compact left-hand boring bar designed for precision turning with TCMT indexable inserts and integrated internal coolant, ideally suited to confined toolposts and universal workshop applications

• Internal coolant through shank
• Compatible with TCMT indexable inserts
• Left-hand orientation for interrupted cuts
• Compact 110 mm overall length

Improved process reliability through proven insert compatibility

The compact holder is supplied to accept TCMT indexable inserts (reference DC--0702), enabling fast index changes and consistent cutting geometry. Compatibility with widely used insert styles reduces tooling complexity on the shop floor and shortens downtime during changeovers. The integrated coolant feed supports stable cutting temperatures and longer insert life, delivering a measurable gain in tool life and surface finish without additional cooling fittings.

Space-saving dimensions that increase setup flexibility

A short overall length of 110 mm and a body diameter of 12 mm, combined with a 10 mm shank, make the holder suitable for tight fixtures and multi-tool turrets. The compact proportions preserve rigidity close to the cutting edge, which helps to reduce chatter and improve repeatability when machining small diameters or deep bores. These dimensional properties are especially beneficial for small-batch production and maintenance workshops that require adaptable, accurate tooling.

Better chip control and cutting performance for left-hand operations

With a 90° cutting angle and a left-hand cutting direction, the holder is optimised for facing and certain interrupted-cut turning tasks where a left-hand approach is advantageous. The internal coolant supply directs fluid to the insert seat, assisting chip evacuation and cooling the cutting zone; this reduces edge wear and supports more consistent machining parameters. For applications sensitive to heat or where chip evacuation is restricted, this arrangement provides clear operational benefits.

Practical advantages for daily workshop use

Engineered as an ISO-conforming A25R STFCL shank-style holder, the component is lightweight at 0.08 kg yet robust enough for routine turning operations. The standardised interface simplifies stock management and ensures interchangeability across conventional insert grades. The design suits general workshop use, precision maintenance, and production environments seeking economical, dependable toolholding that integrates easily into existing tooling systems.
