The Carmex Carbide Tiny Tool is a precision solid carbide grooving tool designed for full-radius grooves in metalworking. Its compact form is ideal for engineers, machinists, tradespeople, and hobbyists working in tight spaces, and it’s also capable of handling general turning tasks.
With a 5.1 mm minimum diameter and a 2 mm groove width, plus a 15 mm reach, this tool delivers reliable, repeatable grooves in challenging pockets. It is built for the MKR line with TNX grade and uses advanced coatings to balance speed, heat, and material compatibility. The BXC coating (PVD TiN) provides strong performance at low cutting speeds and works well with stainless steels, while the BMK coating (sub-micron grade with advanced PVD triple coating) offers extremely high heat resistance and smooth cutting, making it versatile for a wide range of materials.
- Full-radius grooving precision: Delivers accurate, repeatable full-radius grooves in tight spaces, helping you achieve consistent geometry with fewer finishing passes.
- Coating versatility for durability: BXC TiN coating supports low-speed cutting on stainless steels, while BMK’s triple PVD coating delivers high heat resistance and smooth cutting across a broad material range.
- Compact, purpose-built geometry: 5.1 mm minimum diameter, 2 mm groove width, and 15 mm reach enable grooves in confined areas with stable chip flow and minimal tool deflection.
This tool is designed to enhance your workflow by delivering dependable grooving and turning performance, reducing rework, and maintaining consistent results across materials. Its robust carbide core and coated surface help extend tool life and improve surface finish, so you can complete jobs with confidence and efficiency.
