TECWERK Slot Drill Type N 4 mm — HSS-Co8, TiCN-coated, Weldon shank

TECWERK Slot Drill Type N 4 mm for precision slotting and plunge milling in steels, stainless steel and cast materials

• HSS-Co8 substrate for high wear resistance
• TiCN coating for longer tool life
• Centre-cut for plunge and slot milling
• Weldon shank with drive flat for secure clamping

High-performance wear resistance and material suitability

The combination of HSS-Co8 high-speed steel and a TiCN coating delivers a balance of toughness and surface hardness that suits machining of low to medium-strength materials up to approximately 1000 N/mm². This makes the cutter especially effective in standard structural steel and stainless steel, while cast components also machine well. The specification reduces the frequency of tool changes and supports consistent part quality under industrial production conditions.

Geometry that enables plunge work and accurate slotting

The tool’s centre-cut geometry and two-flute design allow safe plunge entry as well as lateral slotting, providing versatility for pocketing and short-length slot operations. With a cutting diameter of 4 mm, a 6 mm shank and a free cutting length of 3.9 mm, the long version is intended for tasks requiring extended reach without sacrificing stability. The Weldon shank with drive flat ensures positive torque transmission and secure clamping in standard holders.

Productivity gains through consistent cutting behaviour

Right-hand cutting and a balanced flute configuration offer reliable chip evacuation and reduced vibration in many common workshop setups, supporting faster cycle times and lower scrap rates. The TiCN layer lowers adhesive wear and improves surface finish for successive parts, resulting in measurable productivity advantages for serial small-part production and repair work in maintenance environments.

Application guidance and integration into workflows

Designed primarily for steel and stainless applications, the cutter is conditionally suitable for non-ferrous and special alloys; users should verify cutting data for high-alloy or soft non-ferrous materials. For optimal results, select holders that match the 6 mm Weldon shank and observe appropriate feeds when plunge-cutting to benefit from the centre-cut feature. For any uncertainties regarding feeds, speeds or holder compatibility, technical advice is available from Metav Werkzeuge to ensure seamless integration into existing processes.

FAQ

Is this cutter suitable for plunge milling into stainless steel?
The TECWERK Slot Drill Type N 4 mm features a centre-cut design and is rated very good for stainless steel, making it suitable for controlled plunge operations when correct feeds and clamping are used.

What clamping system is required for secure machining?
A holder compatible with a 6 mm Weldon shank and drive flat is recommended to ensure secure clamping and positive torque transmission for long-run stability.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and reduces adhesive wear, extending tool life and improving finish on repeated runs with the TECWERK slot drill.

Can this cutter be used on non-ferrous metals and special alloys?
Non-ferrous metals and special alloys are listed as conditionally suitable; machining parameters should be adjusted and a test cut is advised before production use.

What size of slots and pockets is this cutter best for?
With a 4 mm cutting diameter and two-flute geometry, the tool is ideal for narrow slots, short pocketing and detailed work where tool access is limited.
