The Carmex Carbide Tiny Tool – MKR series is a compact solid carbide tool designed for precise full-radius grooving and reliable turning in tight spaces. It’s ideal for engineers, machinists, and hobbyists who need repeatable grooves in stainless steels and general materials. Available in BXC and BMK coatings, it combines low-speed cutting performance with high-heat resistance for a broad range of applications. This tool features 5.1 mm minimum diameter, 1.5 mm groove width, and a 15 mm reach, making it easy to access small corners and intricate features with confidence.

• Full-radius grooving and turning versatility: Precisely forms full-radius grooves while also handling general turning tasks, reducing tool changes and speeding up setups in demanding jobs.
• Coated grades for wide material coverage: BXC TiN-coated grade optimizes cutting at low speeds on stainless steels (ISO P30–P50 / K25–K40), while BMK offers sub-micron, triple-coated durability for high-temperature work (ISO K10–K20).
• Durable carbide with smooth cutting: Solid carbide construction with advanced coatings delivers consistent, chatter-free cutting and long tool life, even in tough materials and extended production runs.

Designed for confident, repeatable results, this tiny tool helps you finish deeper grooves in tighter spaces, streamline tool changes, and achieve cleaner finishes with less downtime. Whether you’re maximizing efficiency in a high-mix workshop or tackling precise work in a home shop, the Carmex Tiny Tool is built to perform reliably across many materials and applications.
