Carmex Carbide Tiny Tool - Face Grooving, BMK Grade, 5 mm minimum diameter x 0.5 mm groove width, is a precision solid carbide bar engineered for straight-face grooves. With a blue-coated body for easy handling, it delivers clean, repeatable slots that support reliable seating and smoother downstream finishing.

As part of the Tiny Tools family, this BMK-grade bar uses a sub-micron carbide substrate with an advanced PVD triple coating. This combination delivers exceptional heat resistance and smooth cutting across a wide range of materials, including stainless steels (ISO P30-P50 / K25-K40), making it a versatile choice for production and prototype work.

• Produces straight grooves for clean slots: Specifically designed for face grooving, it creates straight, accurate grooves rather than rounded ones, improving seating quality and reducing post-processing steps.
• BMK grade coating for high heat resistance: Sub-micron substrate with PVD triple coating (ISO K10-K20) delivers excellent heat resistance and smooth cutting, helping maintain edge life during longer runs.
• Wide material compatibility: Optimized for a broad range of materials, including stainless steels, providing reliable, consistent results across common machining tasks and reducing tool changes.

This tool supports efficient workflows by delivering precise grooves with minimal chatter and wear, helping you reduce downtime, rework, and variability. The BMK coating and carbide construction offer dependable performance across materials, so you can trust it for production runs as well as smaller jobs requiring repeatable, high-quality groove slots.
