TECWERK Slot Milling Cutter – Solid carbide, TiAlN-coated, 3-flute, centre-cutting (D 20 mm)

The TECWERK slot milling cutter is a long, centre-cutting solid carbide tool designed for slotting and groove milling across a wide range of engineering materials, featuring a cylindrical shank to DIN 6535 HB.

• Solid carbide, fine-grain, TiAlN coated
• Centre-cutting, 3-flute geometry
• Cylindrical shank DIN 6535 HB, h6 tolerance
• Vibration-reduced neck relief for roughing/finishing

Precision and productivity for demanding milling tasks

This long, centre-cutting slot cutter combines a solid carbide substrate with a TiAlN coating to deliver high thermal resistance and edge stability during heavy cuts. The three-cutting-edge geometry permits efficient chip evacuation and higher material removal rates while maintaining a fine surface finish. As a result, the tool enables shortened machining cycles and consistent process results, making it suitable where both roughing efficiency and finishing quality are required.

Wide material compatibility reduces tool changes

The cutter’s geometry and coating make it universally applicable: very good performance in steel, cast iron, stainless steel (Cr–Ni steels), non-ferrous metals and aluminium alloys containing silicon, as well as in abrasive and special alloys. This broad suitability minimises the need for frequent tool changes, which improves uptime and lowers total machining costs. The design therefore supports streamlined production for mixed-material batches and flexible job shops.

Geometry and tolerance engineered for stability

Key mechanical characteristics enhance runout control and process reliability: a 20 mm diameter with a cylindrical shank to h6 tolerance, a 19.5 mm free relief length and a small 0.3 mm 45° chamfer for corner protection. The unequal helix and dedicated neck relief reduce harmonics and suppress chatter, particularly in deep slotting operations. These features translate into improved tool life and repeatable accuracy across serial production.

Practical integration into workshop workflows

Designed for both roughing and finishing, the tool supports plunge cuts thanks to its centre-cutting capability and delivers consistent results in vibration-sensitive setups. The standardised shank and DIN designation simplify toolholder selection and inventory management. For operations that prioritise consistent surface integrity and minimal setup variation, this cutter offers a reliable balance between aggressive machining capability and controlled finish quality.

FAQ

Is this cutter suitable for plunging operations?
The TECWERK slot milling cutter is centre-cutting, so it is suitable for plunge operations and for mixed slotting and finishing tasks.

Which materials can be machined with this tool?
The tool performs very well in steel, cast iron, stainless steel, non-ferrous metals and aluminium alloys with silicon, and it is designed to handle abrasive and special alloys.

What does the h6 shank tolerance mean for toolholders?
A h6 shank tolerance ensures precise fit in standard toolholders; this reduces runout and improves repeatability when clamped to DIN-compatible holders.

How does the TiAlN coating benefit workshop processes?
The TiAlN coating increases heat resistance and wear protection, extending cutting life under elevated temperatures and enabling more aggressive cutting parameters where appropriate.

Can this cutter be used for both roughing and finishing?
Yes — the geometry, unequal helix and neck relief make the cutter suitable for efficient roughing while still achieving acceptable finishes for subsequent light machining or polishing.
