The Carmex Carbide Tiny Tool is a purpose-built solid carbide bar designed for deep face grooving. With a 15 mm minimum diameter, 3 mm groove width and 43 mm groove depth, this compact tool delivers precise, robust grooves in challenging materials — including stainless steels — in a small, easy-to-manage form.
This tool is part of a dedicated line of carbide grooving bars designed specifically for deep face operations. The BXC grade features a PVD TiN coating optimized for low cutting speeds, making it well-suited for stainless steels across ISO ranges P30–P50 / K25–K40. The line also includes the BMK option with sub-micron grade and advanced PVD coating for high heat resistance and smooth cutting. Note: this product line doesn’t include bars for left-hand operations.
- Deep-face grooving optimized geometry: Specifically developed to machine deep face grooves, enabling reliable groove formation up to 43 mm deep with a 3 mm width in a single pass.
- PVD TiN-coated BXC grade for low cutting speeds: Coated performance reduces wear and supports consistent cuts on stainless steels across the ISO P30–P50 / K25–K40 ranges.
- Precise carbide construction with defined size: 15 mm minimum diameter provides stable engagement, predictable results, and smooth finishes across materials.
This tool helps you streamline production by delivering consistent groove depth and width, reducing tool changes, and maintaining reliable performance even in stainless steels. The robust carbide core, combined with TiN coating, supports longer tool life and steadier cutting, so you can finish jobs faster with confidence and improved surface quality.
