Boring Bar A16M – 20 mm with internal coolant (Teknik Makina)

The Boring Bar A16M is a 20 mm precision boring bar for DC-- 0702 indexable inserts, designed for left-hand cutting operations in turning and boring tasks.

• 20 mm diameter with internal coolant
• Compatible with DC-- 0702 indexable inserts
• Left-hand cutting, 93° cutting angle
• Shank Ø16 mm, overall length 150 mm

Consistent hole quality at production speed

The compact design with internal coolant provides constant lubrication and improved chip control, which directly reduces thermal distortion and wear. Using a 20 mm diameter tool body together with replaceable DC-- 0702 indexable inserts allows cost-efficient tool management: worn edges are exchanged instead of replacing the whole tool, maintaining cycle times and part tolerances. For production environments this means fewer interruptions and a more predictable process capability.

Secure clamping and straightforward maintenance

A rigid shank Ø16 mm and a defined 93° cutting angle minimise bending and support accurate machining in tight setups. The clamping system is serviced via a Torx T8 key and the specified M2.5x5.5 screw, enabling quick insert changes and consistent seat pressure. Routine maintenance is simplified by accessible fasteners and standardised spare parts, which shortens downtime and keeps the machining cell productive.

Compact design that fits workshop routines

With an overall length of 150 mm and a measured clamping head width of 11 mm, this tool suits confined toolposts and shorter overhangs without sacrificing stability. The left-hand cutting orientation is ideal for specific component geometries and machining sequences where reverse-direction cuts are required. Lightweight construction supports easier handling while retaining the necessary stiffness for accurate boring operations.
