The Carmex Carbide Tiny Tool – Face Grooving is a precision solid carbide bar designed to create straight, true grooves on component faces. Built for demanding fabrication environments, it delivers clean, repeatable grooves with minimal finishing work, making it ideal for engineers, machinists, fabricators, and hobbyists who value consistent results.
Two coating grades optimize performance across materials: BXC Grade with PVD TiN coating provides efficient cutting at lower speeds on stainless steel (ISO P30-P50 / K25-K40); BMK Grade uses a sub-micron substrate with advanced PVD triple coating for excellent heat resistance and smooth cutting across a broader range of materials (ISO K10-K20). The tool features a 5 mm minimum diameter and a 2 mm groove width for compact yet stable groove creation.
- Straight-groove geometry for true face grooves: Delivers clean, flat-bottom grooves with each pass, reducing post-machining finishing and ensuring consistent dimensions.
- Coating-grade versatility for tough materials: Choose BXC TiN-coated grade for low-speed cutting on stainless steels, or BMK sub-micron grade with triple coating for high heat resistance and smooth cutting across metals.
- Rugged carbide substrate with precise dimensions: Solid carbide construction, 5 mm minimum diameter and 2 mm groove width, provides stable cutting performance and repeatable grooves in tight spaces.
The tool is designed to improve workflow by delivering consistent grooves on the first pass, minimizing scrap and rework, and offering reliable performance across common materials. The combination of carbide rigidity and advanced coatings reduces wear and heat buildup, extending tool life and lowering downtime. Whether you're producing precise joints, preparing face grooves for seals, or machining stainless parts, this Tiny Tool helps you achieve professional results with confidence.
