Boring Bar A12-16M, 18 mm with internal coolant — Teknik Makina

The Boring Bar A12-16M is a compact drilling and boring tool designed for use with DCMT 0702 indexable inserts, suited to precision internal boring in small- to medium-sized engineering operations.

• 18 mm diameter for compact bores
• Internal coolant for secure chip evacuation
• 16 mm shank for stable clamping
• Compatible with DCMT 0702 indexable inserts

Consistent concentricity for compact bores

The A12-16M boring bar delivers stable clamping and reduced vibration through its 16 mm shank and compact construction, promoting repeatable concentricity in confined bores. With an outer diameter of 18 mm and a total length of 150 mm, the tool is engineered to keep runout low and to maintain insert position under cutting forces. This leads to fewer rejects and less rework, directly supporting throughput targets in production or toolroom environments.

Improved process reliability with internal coolant

Built-in internal coolant channels provide direct fluid delivery to the cutting zone, improving chip evacuation and temperature control. The result is a steadier cutting edge temperature, extended insert life and a reduced tendency for built-up edge. For operations that prioritise productivity, the internal coolant feature enables higher stable feed rates and contributes to longer tool life without compromising surface finish.

Fast insert changes and secure fixation

The tool is configured for DCMT 0702 indexable inserts and uses a Torx T8 key with an M2.5x5.5 Torx screw, simplifying insert replacement and minimising set-up time. The right-hand cutting orientation and a 95° cutting angle are chosen to suit common turning and boring operations, making the tool straightforward to integrate into existing programmes. Clear mechanical fixation reduces the need for frequent adjustments and supports predictable machining cycles.

Practical handling and workshop compatibility

Weighing only 0.187 kg and featuring a 40 mm insert pocket height, the boring bar balances rigidity with accessibility for manual handling and machine loading. The compact footprint and compatibility with standard DCMT 0702 inserts make the bar suitable for engineering workshops, maintenance shops and small-batch production. The model designation A12-16M and SKU KA514TM simplify inventory tracking and reordering within a centralised tool-management system.

FAQ

What materials is this boring bar suited for?
The boring bar A12-16M (Teknik Cutting Tools, SKU KA514TM) is intended for general internal boring applications using DCMT 0702 inserts; the specific material suitability depends on the insert grade chosen for the operation.

How does the internal coolant benefit machining?
Internal coolant on the KA514TM supplies coolant directly to the cutting edge, improving chip evacuation and thermal control, which helps to extend insert life and maintain consistent surface finish.

Which insert type fits this tool?
This bar accepts DCMT 0702 indexable inserts; the geometry supports a secure fit and efficient cutting when the correct insert grade and clearance are selected for the material.

What fastening hardware is required for insert replacement?
Insert fixation uses a Torx screw M2.5x5.5 operated with a Torx T8 key, enabling quick and secure insert changes on the boring bar.

Can the bar be used on CNC lathes and manual machines?
Yes, the compact design, 16 mm shank and 150 mm overall length of the A12-16M make it suitable for both CNC turning centres and manual lathes, provided the machine offers appropriate clamping and coolant supply.
