Carmex Carbide Tiny Tool is a precision solid carbide grooving bar designed to deliver full-radius grooves on small-diameter workpieces and to handle general turning tasks with ease. Its compact form and 15 mm reach enable access to tight pockets while producing clean, repeatable groove profiles. With a 5.1 mm minimum diameter and a 1.5 mm groove width, this tiny tool is built for accurate, consistent results across a range of materials.

Built in MKR - K20 grade carbide, this tool is offered with two specialized coatings to match cutting conditions: BXC, a PVD TiN-coated grade optimized for low-speed cutting on stainless steels, and BMK, a sub-micron grade with a triple PVD coating for high heat resistance and broad material compatibility. This combination provides durable, reliable performance for both dedicated grooving and general turning applications.

• Two coated performance grades: BXC TiN and BMK triple-coated variants let you tailor cutting performance to your material and speed, extending tool life and delivering consistent finishes.
• Full-radius grooving at small diameter: With a 5.1 mm minimum diameter, 1.5 mm groove width, and a 15 mm reach, you can create precise full-radius grooves in tight spaces without compromising edge quality.
• Rigid, durable carbide construction: The solid MKR-K20 grade substrate provides stable cutting action, minimizes chatter, and supports reliable results across turning and grooving operations.

Designed to streamline your workflow, this tiny tool helps you achieve accurate groove profiles efficiently while reducing setup and downtime. The two coating options let you optimize for stainless steels or broader materials, protecting tool life and improving finish consistency. Its compact reach and robust carbide construction make it a dependable choice for tight pockets, high-precision grooves, and everyday turning tasks, delivering predictable performance and improved overall results.
