The A1 carbide profile cutters from STC58 embody a balance between advanced carbide manufacturing technologies and sophisticated geometry. The brand focuses on creating reliable, predictable and high-performance tools for modern machine tools and traditional equipment. Profile A1 is a classic, reinterpreted to meet modern requirements for efficiency and surface quality.

Key features and design
- Material and base: The cutting plate is made of high-quality fine-grained hard alloy TTK (Tungsten-Titanum Carbide) with a multi-layer wear-resistant coating (TiN, TiAlN or a combination thereof). The coating provides increased heat resistance, reduces abrasive and diffusion wear, extending the durability of the tool by 3-5 times compared to the uncoated alloy.
- Profile geometry A1: This is a universal radius profile with a triangular plate shape and negative geometry. The key characteristic is a large radius at the top (usually 0.8, 1.2 mm or more), which ensures:
- High cutting edge strength.
- Smooth and high-quality chip formation.
- Excellent quality of the treated surface (reduced roughness).
- The ability to work with higher feeds.
- Precision machining: All cutting edges and surfaces of the chip breaker are subjected to fine diamond finishing (grinding or polishing). This minimizes micro-staining, reduces cutting forces and heat, ensuring a stable process and a long service life.
- Chipbreaker: The A1 profile is equipped with a modern chip-crushing groove, optimized for a wide range of feeds and cutting depths. This is critical for the safe and trouble-free handling of viscous materials.
- They are installed on tool holders 2000, 2001, 2002, 2003, 2004, and also on the tool holder for replacement plates of the Mira machine.
Technical advantages
- Versatility: Designed for roughing and semi-finishing of a wide range of materials: structural and carbon steels, alloy steels, stainless steels (austenitic and ferritic), gray and ductile cast irons.
- High durability and stability: Thanks to the combination of a wear-resistant coating and a robust geometry, the tool exhibits minimal and predictable wear, allowing for precise plate replacement planning.
- Durability and reliability: The large radius and negative geometry make the cutter resistant to shock loads and vibrations, which is especially important when cutting intermittently and working on equipment with low rigidity.
- Economic efficiency: The triangular plate has 6 cutting edges (2 on each side), which, combined with increased durability, significantly reduces the cost of processing in terms of one part.
Application areas
- External sharpening: Machining of shafts, flanges, bushings.
- End face: Trimming the ends of discs, rings, and flywheels.
- Contour turning: Processing of smooth radii and chamfers due to the large radius at the top.
- Work on universal lathes, CNC machines and in repair departments. Compatible with machines: Serdi, AZ, Comec, Rottler, Tendtool, THL, Micron, Newen, Saritas, Sunnen and others.
Configuration and identification
The STC58 A1 profile cutters are supplied as interchangeable plates compatible with standard holders (tool holders) from the world's leading manufacturers. The plates are clearly marked according to the ISO standard, including the type, size, radius of the tip, thickness, tolerance class and grade of the alloy.
