The combination of a 20 mm diameter, compact 150 mm overall length and internal coolant reduces heat build-up and improves chip control — order directly via Metav Werkzeuge or consult our specialists for tailored recommendations.

KA109TM 20 mm boring bar A16M – 150 mm with internal coolant (Teknik Makina)

KA109TM is a precision 20 mm boring bar designed for coolant-fed internal machining and ISO A16M toolholders.

• Internal coolant supply
• ISO A16M shank design
• 20 mm diameter, 150 mm overall length
• 11 mm clamping head width

Stable cutting and repeatable bore quality

A compact geometry and an A16M shank ensure stable cutting and consistent concentricity in internal turning operations. With a 20 mm diameter and a 150 mm overall length, the tool balances rigidity and reach to reduce vibration and improve surface finish. This yields measurable advantages in repeatability and reduces the need for rework. For shops aiming to secure tighter tolerances, the combination of controlled overhang and correct clamping form a reliable basis for predictable results.

Effective coolant delivery for consistent chip control

The integrated internal coolant channel supplies cutting fluid directly to the cutting edge, supporting efficient chip evacuation and faster heat dissipation. This targeted supply helps maintain edge condition and dimensional stability during extended cycles, particularly under continuous operation. The tool’s right-hand cut geometry complements directed coolant flow to clear chips away from the bore, improving tool life and reducing interruptions for manual clearing.

Compatibility, serviceability and rapid insert change

Serviceability is straightforward thanks to the standard T8 Torx drive and the supplied M2.5x5.5 fixing screw specification; maintenance routines remain fast and predictable. The 11 mm clamping head width identifies the suitable clamping interface and assists in selecting matching cutting heads or indexable insert holders. These design choices minimise downtime during insert replacement and simplify inventory planning for maintenance teams.

Practical value for workshops and CNC centres

This boring bar supports high-utilisation environments that demand consistent outcomes from coolant-fed setups. It is particularly suitable where compact tooling and reliable chip control are required for internal machining tasks. The design supports operational efficiency through easier setup, predictable maintenance intervals and fewer process interruptions, contributing to a smoother production flow and better use of machine time.

FAQ

What type of toolholder fits this boring bar?
The KA109TM fits holders compatible with an A16M shank; check the toolholder's clamping specification to ensure a secure fit.

Does the boring bar provide internal coolant delivery?
Yes. The KA109TM features internal coolant routing to the cutting edge for improved chip evacuation and thermal control.

Which fastening hardware is required for insert changes?
Insert head assembly uses a T8 Torx drive and M2.5x5.5 fixing screws as specified for the KA109TM.

Is the bar suitable for long overhang applications?
The tool’s compact 150 mm overall length and 20 mm diameter favour reduced overhang; for extended reach, evaluate stiffness requirements against specific machining conditions.
