Boring bar KA254TM (A14Q SDUCL) – left-hand, internally cooled holder

The Boring bar KA254TM is a left-hand, internally cooled toolholder designed for precision boring and turning with SDUC-style indexable inserts, suitable for production lathes and turning centres.

• Left-hand A14Q SDUCL holder
• Internally cooled for effective chip evacuation
• Compatible with DC-- 0702 indexable inserts
• 20 mm diameter, 180 mm overall length

Consistent chip control for uninterrupted production

The KA254TM combines an internally cooled coolant channel with a robust clamping layout to keep the cutting zone clear and temperatures stable. Internal coolant helps flush chips away from the cutting edge and reduces heat build-up, which in turn preserves insert life and maintains consistent surface finish over longer runs. The left-hand orientation and the holder geometry minimise vibration and support predictable tool behaviour when machining bores in a production environment.

Built for compatibility and straightforward integration

The holder carries the ISO designation A14Q SDUCL and is prepared for standard DC-- 0702 indexable inserts, allowing straightforward tool-set harmonisation for shops already using SDUC-style cutters. Key dimensions such as the 16 mm shank, 20 mm diameter and 180 mm overall length make mounting and balance predictable across standard tool turrets and toolposts. The moderate mass (0.263 kg) and compact form aid rapid tool indexing without compromising rigidity.

Faster insert changes and reliable cutting geometry

A secure clamping system (designation 07) and a cutting height of 30 mm permit repeatable insert seating and fast changeovers, reducing downtime. The 93° cutting angle converts to an effective axial cutting geometry that balances radial engagement and cutting force, improving bore roundness while limiting tool deflection. As a consequence, the holder supports efficient material removal with stable chip formation and reliable repeatability—attributes valued in small-batch and high-mix production alike.
