T-nut cutter TKC178TM — 26 mm diameter, for RD-- 12 indexable inserts (Teknik Makina)

The T-nut cutter TKC178TM is a precision T-slot milling tool designed to machine reliable T-slot profiles using RD-- 12 indexable inserts, suitable for fixture plates and tooling applications.

• 26 mm diameter for standard T-slots
• Compatible with RD-- 12 indexable inserts
• 120 mm overall length for deeper slots
• 25 mm shank for rigid clamping

Consistent T-slot geometry for repeatable assemblies

The cutter produces a stable T-slot profile thanks to its 26 mm diameter and controlled geometry, delivering repeatable seating for nuts and fixtures. The use of RD-- 12 indexable inserts simplifies chip control and seat restoration after regrinding or replacement. With an effective cutting length of 30 mm and an overall tool length of 120 mm, the design balances accessibility with stability to maintain consistent dimensions across series production. This leads to fewer rejects and reduced rework in assembly operations.

Secure mounting and vibration control for precision milling

A 25 mm shank ensures secure clamping in standard toolholders and minimises runout, which improves edge life and surface finish. The cutter secures inserts with a Torx T15 drive and M3.5x8.5 clamping screws, enabling reliable seating and repeatable torque during maintenance. The two cutting edges lower cutting forces per tooth, which helps reduce chatter and maintains concentricity when machining T-slots in batches. These features combine to give a predictable, high-quality milling process that supports tighter tolerances.

Efficient handling and straightforward insert changes on the shop floor

Indexable design accelerates maintenance cycles: worn cutting edges are replaced rather than the entire tool, shortening downtime and improving throughput. The tool’s moderate weight of 0.415 kg and its compact profile make handling simple during tool changes, while the TKC178TM label supports clear inventory tracking. For production planners, this cutter represents a pragmatic balance between serviceability and machining performance, supporting continuous operation with minimal intervention and clear parts identification for replenishment.

FAQ

Which insert type fits this cutter?
The cutter uses RD-- 12 indexable inserts; the system is designed for straightforward replacement and chip control with that insert family.

What shank diameter is required for secure clamping?
A 25 mm shank is specified for stable clamping and reduced runout when the tool is held in a compatible holder.

How deep can the cutter machine a T-slot?
The tool has a cutting length of 30 mm and an overall length of 120 mm, which determines the practical slot depth and access in most fixture setups.

How many cutting edges does the tool have and why does that matter?
The cutter has 2 cutting edges, which balances material removal rate and cutting force per tooth to reduce vibration and improve surface finish.

Is this cutter suitable for series production and quick maintenance?
Yes; the indexable insert concept and simple clamping with Torx T15 / M3.5x8.5 screws enable fast insert changes and sustained productivity in production environments.
