Carmex Carbide Tiny Tool - Face Grooving bars are solid carbide tools engineered for precise, repeatable face grooves. With a 6 mm minimum diameter and a 1.5 mm groove width, they deliver straight grooves and flat faces for clean finishes across a wide range of materials, including stainless steels.
From the Tiny Tools family, these bars are designed to maximize reliability and ease of use in professional shops and hobbyist setups. They offer coating options to match cutting conditions: BXC TiN-coated grade for low cutting speeds on stainless steels, and BMK sub-micron grade with advanced PVD triple coating for exceptional heat resistance and smooth cutting—making them versatile for general-purpose use across materials.
- Straight-groove geometry for precise faces: Delivers straight, flat grooves with clean edges, reducing post-processing and ensuring repeatable results on every part.
- Coatings for durability and versatility: BXC TiN coating enhances wear resistance at low speeds (ideal for stainless steels), while BMK’s triple PVD coating provides excellent heat resistance and smooth cutting across a broad material range.
- Rugged carbide construction for long tool life: Solid carbide design from the Tiny Tools line delivers stiffness and reliable performance, helping minimize tool changes and maximize productive machining time.
This tool set helps you achieve consistent groove quality, improves workflow by reducing finishing steps, and extends tool life across multiple materials. With precise dimensions and proven coating options, you can rely on predictable results, fewer interruptions, and a professional finish on every grooving job.
