VT120TM screw-in cutter — 25 mm diameter, M12 thread by Teknik Makina

The VT120TM screw-in cutter is a compact milling head designed for light to medium duty milling with RDMT 12T3 indexable inserts, ideal for tight setups and quick tool changes in production and repair shops

• 25 mm cutting diameter
• M12 screw-in thread
• Two cutting edges for balanced cutting
• 55 mm overall length

Faster setup and shorter cycle times with screw-in design

The screw-in design with a robust M12 thread and a modest overall length delivers a practical way to reduce tool change time and maintain machine accessibility. Thanks to the compact geometry and 25 mm cutting diameter, the tool is particularly suited to operations where space is limited but stability remains essential. The two cutting edges ensure even load distribution, which improves run stability and contributes to consistent surface quality. The assembly requires only a Torx driver, keeping clamp times predictable and repeatable for small-batch and series production alike.

Reliable clamping and easy insert handling for continuous operation

A secure clamping system is crucial for predictable machining. The head is prepared with a locking screw M3.5 and a Torx screw M3.5x8.5, operated with a Torx T15 key, allowing quick but secure replacement of indexable inserts. The specified 22 mm thread height and 33 mm cutting height are matched to the insert geometry, enabling confident seating of RDMT 12T3 indexable inserts and minimising micro-movement under cut. With a tool mass of just 0.106 kg, dynamic response is improved while still offering enough mass to dampen chatter in many common finishing and semi-finishing applications.

Compact form factor that supports flexible workshop layouts

The short 55 mm overall length and screw-in configuration make the head easy to integrate on arbors and holders where space is constrained. The reduced projection lowers bending moments and helps preserve spindle life when compared with longer tool assemblies. This compactness, combined with the standard M12 interface, suits both portable retrofit tasks and centralised CNC workstations, enabling shops to keep a smaller inventory of fixtures while achieving versatile machining options.

Durable performance with predictable maintenance intervals

Constructed for straightforward use, the cutter balances ease of maintenance with dependable machining characteristics. The combination of secure Torx fastening and straightforward insert indexing keeps routine servicing quick and low-risk. When paired with suitable RDMT 12T3 indexable inserts, the head supports repeatable parameters across production runs, helping to maintain consistent part tolerances and surface quality while keeping downtime to a minimum.

FAQ

Which inserts fit this screw-in cutter?
The head is specified for use with RDMT 12T3 indexable inserts; the VT120TM is configured to accept the standard geometry and seating of that insert series.

How is the insert secured and changed?
Inserts are secured with the supplied Torx screw (M3.5x8.5); removal and fitting are performed with a T15 Torx key for reliable, repeatable clamping.

Is the cutter suitable for small machines with limited tool clearance?
Yes, the 55 mm overall length and M12 screw-in interface make the cutter appropriate for confined spaces where projection needs to be minimised.

What balance can be expected for serial machining?
With two cutting edges and a compact design, the tool provides balanced cutting behaviour for many light and medium duty serial operations; machine-specific balancing should follow the spindle manufacturer’s guidance.
