TECWERK Mini slot cutter 5 mm — HSS‑Co8, 3‑flute, 6 mm Weldon shank

The TECWERK Mini slot cutter 5 mm is a short, centre‑cutting three‑flute cutter designed for precision slotting and keyway work in materials up to approximately 800 N/mm².

• Short 3 mm cutting length
• HSS‑Co8 for improved wear resistance
• 6 mm Weldon shank with drive flat
• Very good for steel and cast iron

Compact design that delivers precise slotting

The short geometry and 3‑flute configuration produce a stable, vibration‑resistant cut, which is particularly valuable when machining narrow slots or limited‑access features. The centre‑cutting geometry allows plunge starts, while the reduced overall length improves rigidity and repeatability. For workshops needing reproducible groove profiles, the compact design reduces chatter and delivers cleaner slot walls, improving downstream assembly and fit.

Material performance and application scope

Manufactured from HSS‑Co8, the tool offers enhanced hot‑hardness and wear resistance compared with standard high‑speed steel, making it a robust choice for demanding short‑run operations. Suitability is optimised for steel (very good) and cast iron (very good); non‑ferrous alloys and stainless steel are machineable but may require conservative feeds and cuts. The cutter is rated for materials with tensile strengths up to ~800 N/mm², enabling confident selection where moderate material strength is encountered.

Shank, mounting and machining advantages

A 6 mm Weldon shank with a drive flat ensures reliable torque transmission in ER‑collet holders and chucking systems; the compact 39 mm overall length and 6 mm shank diameter suit small milling machines and compact setups. The 5 mm nominal diameter and 3 mm cutting length allow precise control over slot depth while preserving core strength of the cutter. Right‑hand cutting direction and the three cutting edges balance material removal rate with surface finish, making the tool efficient for both single‑pass and finish‑pass milling.

FAQ

What materials is the mini slot cutter suitable for?
The TECWERK mini slot cutter is very well suited to steel and cast iron; machining of non‑ferrous metals and stainless steel is possible but should be approached with adjusted feeds and speeds.

Can this cutter be used for plunge milling?
Yes, the centre‑cutting geometry allows plunge starts; the short design helps maintain rigidity during plunge operations.

What holder is recommended for secure clamping?
A 6 mm Weldon shank requires a compatible holder or chuck with a set screw or a Weldon‑compatible collet system to ensure positive torque transmission.

How deep can the cutter cut in a single pass?
The nominal cutting length is 3 mm; single‑pass depths should not exceed the cutting length and should be selected according to material and machine rigidity.

Is the tool suitable for high‑speed applications?
Made of HSS‑Co8, the cutter tolerates higher cutting temperatures than standard HSS, but machining parameters must match the machine capability and workpiece material.
