TECWERK 15 mm HSS‑Co8 Slot Cutter (TiCN), Weldon Shank — DIN 844 Type N

The TECWERK 15 mm HSS‑Co8 slot cutter is a long, centre‑cutting grooving tool designed for precision milling of steel, stainless steel and cast materials in industrial and workshop settings.

• HSS‑Co8 for high heat resistance and toughness
• TiCN coating for extended tool life and wear protection
• Weldon shank with drive flat for secure clamping
• Centre‑cutting three‑flute geometry for accurate plunging

Proven material and coating for longer service life

The cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel chosen for its elevated red hardness and resistance to deformation at higher cutting temperatures. With the TiCN coating applied, abrasive wear is reduced and the usable life of the tool is extended, which in turn lowers tooling costs per component in repetitive production work. This combination is particularly effective where thermal loads and intermittent contact with hardened zones occur, so fewer tool changes are required and machine uptime increases.

Geometry and shank for reliable machining accuracy

Built to DIN 844 Type N with a three‑flute long profile and centre‑cutting geometry, the cutter enables guided plunge starts and consistent groove dimensions. The Weldon shank with drive flat ensures secure torque transmission in set‑screw holders, reducing slippage and runout during heavy engagement. As a result, chip formation remains stable and surface finish is improved, which benefits downstream processes such as assembly or coating.

Material suitability and recommended applications

This tool is rated for machining materials up to approximately 800 N/mm² with an uncoated cutter and up to 1,000 N/mm² when used with the TiCN coating, making it well suited to common steels, stainless steel and cast iron, where it performs very well. Non‑ferrous metals and special alloys are conditionally applicable depending on cutting data and coolant strategy. For users processing mixed batches, the cutter delivers a balanced performance that reduces the need for frequent tool changes.

Practical integration into workshop and CNC setups

With a 15 mm diameter cutting head and a 12 mm shank, the cutter fits standard collet and Weldon holders, allowing straightforward integration into milling centres and manual milling machines. The specified tolerances for nominal diameters (9–15 mm: h10) support consistent interchangeability across tool holders and fixtures. Operators will appreciate the combination of robust clamping and centre‑cutting capability when programming pocketing or slotting cycles, while planners benefit from predictable tool life and repeatable results.

FAQ

Which materials are best machined with this cutter?
The TECWERK 15 mm slot cutter is very well suited to steel, stainless steel and cast iron; non‑ferrous metals and special alloys are usable with adapted cutting data.

Can this tool perform plunge cuts?
Yes, the centre‑cutting geometry allows controlled plunging and slot starts when programmed accordingly in milling routines.

What holder and clamping are recommended?
A Weldon holder with set screw engaging the drive flat is recommended to secure the 12 mm shank and reduce slippage under load.

Does the TiCN coating significantly extend tool life?
The TiCN coating offers improved abrasion resistance and is especially effective when machining harder or abrasive steels, extending service intervals compared with uncoated cutters.

Are there other diameter tolerances available?
Nominal diameters up to 15 mm are supplied to h10 tolerance; other sizes and tolerance classes are noted as e8 where applicable.
