4mm Slot Drill DIN 6527L Type N Solid Carbide TiAlN Coated 3-Flute Long 45° Chamfer 6mm Shank - TECWERK

Take advantage of solid carbide construction and TiAlN coating for extended tool life and higher cutting speeds; the long three‑flute design offers depth access with reduced vibration for consistent finishes. Order the slot drill directly via Metav Werkzeuge or ask our consultants if needed.

Slot drill DIN 6527L Type N, 4 mm — VHM, TiAlN, long (TECWERK)

The Slot Drill DIN 6527L Type N is a long, three‑cutting‑edge slot cutter designed for machining mixed materials where depth access and low vibration are required, suitable for both roughing and finishing tasks

• Solid carbide (VHM) with TiAlN coating
• Three-flute slot drill with centre cut
• Long design for depth and low-vibration cutting
• Cylindrical shank to DIN 6535 HB, h6 tolerance

High‑performance cutter for mixed materials and abrasive tasks

Manufactured from solid carbide and finished with a TiAlN coating, this long slot cutter delivers improved heat resistance and wear performance compared with uncoated alternatives. The three‑flute geometry with a centre cut enables controlled material removal and safe plunging, while the tool’s geometry is optimised for steels and harder workpieces as well as for aluminium with silicon and more abrasive materials. The outcome is higher process reliability and a stable cutting edge retention over extended cycles.

Stable long form for deep pockets and vibration‑sensitive operations

The long design combined with unequal pitch and a dedicated neck relief helps to suppress chatter in extended overhang situations. The cylindrical shank to DIN 6535 HB with h6 tolerance ensures secure clamping and low runout in ER collets and precision chucks, which directly improves repeatability and surface integrity when machining deep grooves or narrow slots. These mechanical measures enable production of consistent components with fewer re‑works.

Geometry and coating that improve throughput and tool life

A centre cut provides axial cutting capability for interrupted cuts and plunge operations, while the TiAlN surface helps maintain cutting performance at high‑speed conditions by forming a protective oxide layer that resists thermal wear. Together with the fine‑grain carbide substrate, the tool reduces the frequency of tool changes and supports shorter cycle times without compromising finish, making it suitable for both roughing and finishing steps in batch production.

Practical handling and compatibility with standard toolholders

The tool’s shank and relief dimensions are tailored for workshop integration: a 6 mm shank diameter fits common clamping systems and the modest chamfer and relief geometry protect the edges during entry. Right‑hand cutting orientation and the long‑reach profile make the cutter versatile for slotting, profiling and pocket entry in diverse alloys and cast materials. The combination of mechanical design and coating supports a straightforward setup and predictable performance on the shop floor.

FAQ

What materials can be machined with this slot drill?
The TECWERK slot drill is suitable for a wide range of materials, including steel, stainless steels, various cast irons, non‑ferrous metals and aluminium with silicon, as well as certain abrasive and special alloys.

Can the tool be used for plunge cutting?
Yes, the built‑in centre cut enables safe axial engagement and controlled plunging for slotting operations and interrupted cuts.

What clamping systems are compatible with the shank?
The cylindrical shank conforms to DIN 6535 HB with h6 tolerance and is compatible with standard ER collet chucks and precision holders used in general workshop and CNC setups.

Is this cutter more suitable for roughing or finishing?
The geometry and coating make the cutter versatile for both roughing and finishing; its vibration‑reduced design supports stable roughing, while the fine‑grain carbide and TiAlN preserve edge life for finishing passes.
