VT128-1TM Screw-in milling cutter for RDMT 12T3 – 40 mm, internal coolant (Teknik Makina)

The VT128-1TM screw-in milling cutter is a compact cutter engineered to accept RDMT 12T3 indexable inserts, offering a secure screw-in connection and targeted coolant delivery for efficient milling in production and job-shop environments.

• 40 mm cutter diameter for stable cutting
• Internal coolant for improved chip evacuation
• M16 screw-in connection with 24.5 mm thread height
• Four cutting edges with 35.5 mm cutting height

Engineered for secure clamping and precision milling

The screw-in construction with an M16 thread and a thread height of 24.5 mm provides a mechanically robust connection that reduces runout and vibration during milling. With a 40 mm cutter diameter and an overall length of 60 mm, the tool balances rigidity and accessibility, enabling steady cutting forces and repeatable results in series production. The design is optimised for use with RDMT 12T3 indexable inserts, which simplifies tool management and keeps inventory straightforward. This mechanical reliability translates into shorter downtime and more predictable cycle times on CNC milling heads and machining centres.

Efficient coolant supply and consistent surface quality

The built-in internal coolant channel directs cooling fluid directly to the cutting zone, promoting efficient heat removal and improved chip evacuation. Combined with the tool’s four cutting edges and a cutting-edge height of 35.5 mm, this cooling concept supports higher material removal rates while maintaining a stable cutting edge temperature. The result is a more consistent surface finish and reduced thermal wear on inserts, so insert change intervals can be extended under comparable cutting conditions. For wet machining strategies where controlled coolant delivery is important, this cutter provides a practical technical advantage.

Fast insert changes and standardised maintenance

Routine maintenance is simplified thanks to the standardised fastening: the insert is secured with a Torx screw (use Torx T15) sized M3.5x8.5, allowing rapid cartridge changes with common workshop tools. The tool’s compact mass (0.23 kg) and 60 mm overall length contribute to manageable handling during set-up and quicker workstation cycles. These characteristics reduce non-cutting time and streamline tool change procedures in multi-shift environments. The screw-in format also avoids the need for clamping adaptors, helping to keep the tooling system compact and repeatable.

Broad applicability and supply reliability

Designed for general milling tasks where RDMT 12T3 inserts are specified, the cutter is suited to a range of machining scenarios in metalworking shops and production lines. As part of a structured tooling portfolio, the component benefits from Teknik Makina’s manufacturing standards and from Metav Werkzeuge’s distribution and quality-filtering in Europe, ensuring consistent availability and traceable delivery. For customers seeking reliable tooling that integrates with standard indexable inserts and common maintenance procedures, this screw-in cutter represents a pragmatic choice that supports productivity and operational continuity.
