The Carmex Carbide Tiny Tool is a compact solid carbide bar designed for full-radius grooving on small-diameter workpieces and it also handles general turning tasks. It features a 5.1 mm minimum diameter, a 1.5 mm groove width, and a 15 mm reach, enabling precise radii in tight spaces.
This MKR tool is offered in two PVD-coated grades for versatile material handling: BXC TiN-coated for low-speed grooving on stainless steels (ISO P30-P50 / K25-K40), and BMK, a sub-micron grade with an advanced PVD triple coating that delivers exceptional heat resistance and smooth cutting across a wide range of materials. Both grades are designed for reliable, repeatable performance in everyday machining.
- Full-radius grooving capability: Delivers precise full-radius grooves on small-diameter workpieces (minimum 5.1 mm) with a groove width of 1.5 mm and a 15 mm reach, enabling consistent radii in tight spaces.
- Two-grade PVD-coated carbide for versatility: Choose BXC TiN for low-speed grooving in stainless steels or BMK with triple PVD coating for high heat resistance and smooth cutting across many materials.
- Durable, general-purpose design: Solid carbide construction and optimized geometry provide reliable performance for general turning and a wide material range, helping to reduce downtime and extend tool life.
The Tiny Tool supports efficient workflows by delivering repeatable radii and clean finishes in challenging pockets. Its compact geometry and 15 mm reach minimize setup changes, while the two coating options let you tailor performance to your material and speed requirements. This combination helps you complete jobs faster, with consistent results across stainless steels and other materials.
