Bohrstange (Boring Bar) AP347TM

The Bohrstange (Boring Bar) AP347TM is a left‑hand PCLN holder designed for use with CNMG Indexable Inserts, providing precise chip control and reliable internal coolant delivery for medium‑duty turning operations.

• Boring Bar AP347TM by Teknik Makina
• Internal Cooling for improved Chip Evacuation
• Fits CNMG 09T3 Indexable Inserts
• Left‑hand orientation with 95° Cutting Angle
• Shaft Ø 20 mm, Cutting Ø 26 mm, Length 200 mm

Robust Design for Consistent Performance

The AP347TM combines a A20R PCLNL ISO designation with a compact, rigid geometry that reduces vibration and improves surface finish. Its Shaft Ø 20 mm and optimised head geometry ensure stable clamping and repeatable tool positioning, which translates into fewer re‑setups and higher throughput. The holder’s construction is intended to work with standard Indexable Inserts, allowing rapid insert changes and predictable cutting behaviour.

Internal Cooling and Chip Management that Pays Off

Equipped with Internal Cooling, the tool channels coolant directly to the cutting edge, improving Chip Evacuation and thermal management. This targeted cooling reduces cutting edge temperature, which helps to prolong Insert life and maintain dimensional accuracy during longer runs. For operations where chip control and tool life are critical, the integrated coolant path offers a measurable reduction in unplanned stoppages and rework.

Compatibility and Practical Application

Designed for CNMG 09T3 inserts, the holder accepts common triangular‑style indexable plates and uses the TA023 clamp plate together with Pin TS3 and Lock Lever TL3 to secure the Insert. The left‑hand orientation and 95° Cutting Angle make the tool suitable for facing, finishing passes and light shoulder work on a wide range of steels and non‑ferrous materials. For those less familiar: Indexable Inserts are replaceable cutting tips that allow quick renewal of the cutting edge without regrinding, which keeps setup time to a minimum.

Simple Handling, Clear Maintenance Steps

Maintenance focuses on keeping coolant channels clear and ensuring the clamping components are correctly assembled. The clamping screw uses a 2.5 Allen key for secure, repeatable tightening; replace Inserts as wear indicates and flush the Internal Cooling channels periodically to avoid clogging. Proper routine care preserves cutting geometry and sustains stable cutting forces, supporting consistent part quality across batches.

FAQ

What inserts fit the AP347TM Boring Bar?
The AP347TM Boring Bar from Teknik Makina is designed for CNMG 09T3 Indexable Inserts; use the specified CNMG‑format plates for correct seating and reliable clamping with the TA023 clamp plate.

Does the tool provide coolant to the cutting edge?
Yes, the AP347TM includes Internal Cooling and is specified "with Coolant", so coolant is delivered through the holder directly to the cutting zone to aid chip evacuation and temperature control.

Which direction of cut is this holder for?
This holder is produced for left‑hand cutting operations and features a 95° Cutting Angle, making it suitable for left‑hand facing and finishing tasks.

What clamping accessories are required?
The AP347TM uses the TA023 clamp plate with Pin TS3 and Lock Lever TL3; the clamping screw is tightened with a 2.5 Allen key for secure and repeatable clamping.

What is the ISO designation and how does it help?
The ISO designation A20R PCLNL identifies the holder geometry and mounting style, ensuring compatibility with toolpost fixtures and clarifying the orientation and Insert type for correct application planning.
