TECWERK slot drill DIN 6527L · 12 mm · VHM · TiAlN

A long, three‑flute slot drill designed for low‑vibration roughing and finishing across a wide range of metals, supplied with a cylindrical shank to DIN 6535 HB

• Solid carbide, TiAlN coating
• Three‑flute centre‑cut geometry
• Cylindrical shank DIN 6535 HB h6
• Low‑vibration design for roughing and finishing

Faster, more consistent cutting with durable carbide and TiAlN

The combination of solid carbide (VHM) substrate and TiAlN coating gives a clear performance advantage when machining mixed batches of materials. The coating increases surface hardness and thermal resistance, which translates into longer tool life and more stable cutting conditions at elevated temperatures. The centre‑cut, three‑flute design contributes to balanced forces during engagement, enabling plunge cuts and slotting with improved chip control. These technical choices reduce downtime for tool changes and support a more predictable production rhythm.

Secure clamping and repeatable accuracy for busy shops

A consistent clamping interface is central to precision work: the tool is supplied with a 12 mm cylindrical shank to DIN 6535 HB, tolerance h6, delivering reproducible seating in collets and toolholders. The neck relief and unequal helix geometry are engineered to dampen chatter, which enhances dimensional stability and surface quality in through‑slot and shoulder operations. For workshops that demand repeatable accuracy across series production, this specification helps minimise rework and inspection cycles.

Versatility across ferrous and non‑ferrous materials

The geometry and coating make the cutter suitable for a broad material mix: steel, cast iron, Cr‑Ni (stainless) steels, non‑ferrous metals and aluminium alloys with silicon content, as well as certain abrasive materials. The moderate 45° chamfer and small protection chamfer (0.2 mm) protect the cutting edge while allowing reliable entry into workpieces. Because the tool is suitable for both roughing and finishing passes, inventory can be consolidated, reducing the number of specialised cutters required on the shop floor.

Practical dimensions and application scope for machining strategies

Key dimensions such as a 12 mm diameter, overall length 83 mm, effective length 35 mm and cutting length 3 mm define the tool’s reach and engagement limits. The relatively long body supports deeper setups while the short cutting length focuses performance where material removal is required. The three cutting edges and unequal helix improve chip evacuation in slotting operations, and the right‑hand cutting direction suits standard machining cycles. For process planning, the tool is a pragmatic choice where robustness and adaptability are prioritised.

FAQ

Is this cutter suitable for plunge cutting and slotting?
Yes. The TECWERK slot drill features a centre‑cut three‑flute geometry that allows plunge entry and reliable slotting in appropriate setups.

Which materials can be machined with this tool?
The tool is designed for a wide range of materials including steel, grey and malleable cast iron, Cr‑Ni steels (stainless), non‑ferrous metals and aluminium alloys with silicon content.

What are the shank specifications for holder selection?
The cutter has a 12 mm cylindrical shank to DIN 6535 HB with tolerance h6, ensuring repeatable clamping in standard collets and toolholders.

How does the TiAlN coating help in production?
The TiAlN coating increases thermal resistance and surface hardness, which supports higher cutting temperatures, reduces wear, and extends tool life under demanding conditions.

Is this tool intended for roughing, finishing, or both?
Both. The geometry and coating provide the stiffness and edge protection required for effective roughing, while the balanced flute design supports finishing passes with good surface results.
