The Carmex Carbide Tiny Tool – Chamfer & Boring (MCL) is a precision cutting tool designed for small chamfering and boring applications. This compact tool is ideal for engineers, manufacturers, and hobbyists who need clean, accurate chamfers and tight bores on miniature parts and components.

Built from premium K20-grade carbide, it delivers outstanding hardness and wear resistance. Its compact geometry—5.1 mm minimum diameter and 15 mm reach—combined with a left-hand design, lets you access tight features and maintain consistent cuts in cramped spaces.

• Ultra-compact reach for tight features: The 5.1 mm minimum diameter and 15 mm reach enable precise chamfering and boring on small parts and recessed areas without tool swaps, speeding setups and minimizing handled tolerances.
• Durable K20 carbide construction: Premium-grade carbide provides high hardness and excellent wear resistance, delivering long tool life and consistently sharp edges for repeatable results.
• Left-hand cutting geometry: Designed for machines configured for left-handed tooling, ensuring the correct cutting direction and reliable performance in mirrored or specialized setups.

Whether you’re prototyping, performing maintenance on compact assemblies, or working on small-bore features, this tiny tool helps you achieve accurate chamfers and precise bores quickly. The combination of small diameter, sufficient reach, and durable carbide supports faster workflows, fewer tool changes, and dependable results across demanding small-part applications.
