KE78TM Thread Boring Bar — Solid‑carbide tool with internal coolant (Teknik Makina)

The KE78TM thread boring bar is a purpose‑built tool for producing internal threads with indexable inserts; it suits CNC turning centres and dedicated threading stations where rigidity and coolant delivery are required.

• Solid carbide construction
• Internal coolant feed
• Compatible with 22 IR inserts
• Right‑hand cutting, ISO E20S

Precision that keeps production running

The monoblock solid carbide construction delivers high stiffness and dimensional stability under load, reducing chatter and prolonging tool life compared with less rigid designs. Built to accept the 22 IR indexable system, the bar transfers cutting forces cleanly through the holder and into the machine spindle, which translates into repeatable thread form accuracy and fewer rework cycles. The ISO designation E20S indicates a standardised interface for secure location and predictable performance in automated setups.

Consistent coolant control for better chip evacuation

An integrated internal coolant channel provides directed fluid delivery straight to the cutting zone, aiding chip control and temperature management during the threading operation. This targeted cooling reduces built‑up edge and thermal distortion, improving surface finish and thread consistency across long production runs. For operations where cycle time and first‑pass yield matter, the combination of internal coolant and carbide rigidity supports higher metal removal stability and reduced cycle‑to‑cycle variance.

Secure clamping and serviceable components

The bar is prepared for the IR22 clamping system and secures inserts with the supplied Torx fastenings (Torx T15 screws and M4x11 fixing screws), ensuring reliable insert retention under intermittent thread depths and interrupted cuts. The E20S shank form and 20 mm shank diameter provide compatibility with common toolholders while the 15.6 mm cutting height affords proper insert engagement for standard internal thread profiles. These mechanical details simplify setup and replacement procedures, limiting downtime between tool changes.

Designed for industrial threading tasks

With an overall length of 250 mm and a body diameter of 24.5 mm, the bar is engineered for balance between access into bores and the stiffness required for accurate internal profiling. Right‑hand cutting geometry suits standard turning and threading directions prevalent in most machine tool operations. The KE78TM is therefore appropriate for series production and maintenance tasks where a robust, repeatable threading solution is required, and where the economy of indexable inserts brings measurable savings over time.

FAQ

Which machines is this bar suited for?
The KE78TM thread boring bar from Teknik Makina is intended for use on CNC turning centres and compatible threading stations where an E20S shank and IR22 clamping system can be accommodated.

Which insert type is required for operation?
This bar accepts 22 IR indexable inserts; secure the inserts with the specified Torx fasteners (T15 and M4x11) to maintain correct seating and cutting geometry.

Is coolant delivery supported and why does it matter?
Yes — the KE78TM features internal coolant to direct fluid to the cutting edge, improving chip evacuation, heat control and surface finish during internal threading.

What are the main benefits of the solid‑carbide body?
The solid‑carbide construction increases rigidity and wear resistance, helping to preserve thread form accuracy and extend service intervals compared with less rigid tool bodies.
