4mm Slot Drill DIN 6527K Type N Solid Carbide TiAlN Coated, 45° Chamfer, Z3 Short - TECWERK

Take advantage of a highly versatile, solid carbide cutter with TiAlN wear protection and a vibration‑resistant geometry to keep cycle times steady and tool changes to a minimum. Order the tool through Metav Werkzeuge or consult our advisors for process‑matched recommendations.

TECWERK Slot Drill DIN 6527K Type N, 4 mm — Solid Carbide, TiAlN-coated, 3 flutes

The TECWERK slot drill DIN 6527K Type N, 4 mm is a short, three‑flute solid‑carbide cutter designed for vibrationally stable roughing and finishing across steels, cast irons and non‑ferrous materials

• Solid carbide VHM, fine‑grain, TiAlN coated
• Short 3‑flute design with centre cut
• Cylindrical shank to DIN 6535 HB, shank Ø 6 mm
• Universal for steel, cast iron and non‑ferrous metals

Consistent performance where throughput matters

The combination of solid carbide construction and a TiAlN surface layer offers a tangible increase in wear resistance and heat stability compared with uncoated tools. This results in more reliable tool life under interrupted cuts and during heavier engagement, which in turn reduces machine downtime and tooling costs. The cutter’s Ø 4 mm diameter and centre‑cut geometry allow plunge operations and fast slotting, making it suitable for mixed production runs that demand repeatable results.

Reduced vibration for better surface quality

A deliberately unequal pitch and neck relief provide improved stability by breaking up harmonic excitation during cutting. The vibration‑resistant short design lets the tool run smoother at common spindle speeds, producing a finer finish when planed against roughing passes. In practical terms, bosses and shoulders require fewer manual touches after machining, while the risk of chatter marks is minimised even in less rigid set‑ups.

Straightforward clamping and machine compatibility

The tool is supplied with a cylindrical shank compliant with DIN 6535 HB and a shank Ø 6 mm with h6 tolerance, simplifying holder selection and ensuring secure clamping. The integrated 45° chamfer on the margin protects the cutting edges on entry, while the short flute length and 3‑edge design support stable chip evacuation. These features help shorten set‑up time and support consistent process parameters across different machines.

Broad material suitability and machining strategy

Thanks to a newly developed geometry and the TiAlN coating, the cutter is rated very good for machining steel, stainless steels, cast irons, special alloys and a range of non‑ferrous metals including aluminium with silicon content and abrasive materials. Use the tool for both roughing and finishing operations: a heavier, conservative roughing pass followed by a lighter finishing pass will exploit the tool’s wear resistance and centre‑cut capability to produce accurate slots and pockets with minimal rework.

FAQ

What materials can this slot drill machine effectively handle?
The TECWERK slot drill is rated very good for steel, stainless steel, cast iron, non‑ferrous metals and aluminium with silicon; the TiAlN coating extends life when machining abrasive alloys.

Is the tool suitable for plunge cutting and slotting?
Yes, the centre‑cut geometry and 3‑flute design enable plunge operations and effective slotting with the TECWERK cutter, while the 45° protective margin preserves edge life on entry.

What shank standard and tolerance are supplied?
The cutter comes with a cylindrical shank to DIN 6535 HB, shank Ø 6 mm and h6 tolerance for secure and repeatable clamping.

How does the unequal pitch affect machining?
The unequal pitch reduces harmonic excitation and therefore lowers the risk of chatter, improving surface finish and tool life during both roughing and finishing cycles.

Can the tool be used for both roughing and finishing passes?
Yes, the tool’s geometry and TiAlN wear protection make it suitable for a two‑step approach: conservative roughing followed by a lighter finishing pass to achieve dimensional accuracy and surface quality.
