The Carmex Carbide Tiny Tool is a solid carbide bar engineered for face grooving with a built‑in chip breaker. It’s designed for an 8 mm minimum diameter and a 3 mm groove width, delivering straight grooves for clean, predictable results and easier downstream finishing.

As part of the Tiny Tools family, this BMK-grade bar uses an advanced PVD triple coating to deliver exceptional heat resistance and a smooth cutting experience. It performs reliably with stainless steels and a wide range of materials, making it a versatile, general‑purpose choice for production runs, repair work, and hobbyist projects alike.

• Straight groove geometry for precise face grooves: Delivers straight, uniform grooves instead of rounded profiles, reducing finishing work and improving part fit and surface consistency.
• BMK-grade coating for durability and heat resistance: Sub‑micron PVD triple coating provides long tool life and smooth cutting, maintaining performance under higher temperatures and tougher materials.
• Wide material compatibility for versatile use: Optimized for stainless steels (ISO P30–P50 / K25–K40) and suitable as a general‑purpose tool across a broad range of materials and applications.

This tool supports faster setups, consistent groove quality, and reduced downtime thanks to durable coatings and a design tailored for face grooving with chip control. Whether you’re optimizing a production line or tackling a one‑off project, it helps you achieve reliable, repeatable results with less rework and greater overall efficiency.
