Carmex Carbide Tiny Tool - Full Radius Grooving - MKR - K20 Grade - 7.1mm Minimum Diameter x 1mm Groove Width - 22mm Reach

The Carmex Carbide Tiny Tool is a compact, solid carbide bar engineered for full-radius grooving and versatile turning on tight workpieces. Designed to deliver clean radii and consistent finishes, it’s a reliable choice for engineers, machinists, hobbyists, and shop floor operators tackling small-diameter grooves. Key specs include a 7.1 mm minimum diameter, a 1 mm groove width, and a 22 mm reach to handle confined setups with confidence.

The tool is part of the MKR grade family and is available with two robust PVD-coated options to suit different materials and speeds. BXC is a TiN-coated grade optimized for low cutting speeds and stainless steels, while BMK is a sub‑micron grade with a triple PVD coating that offers excellent heat resistance and smooth cutting. These coatings help extend tool life and maintain steady performance across a range of materials, including ISO P30‑P50 / K25‑K40 and ISO K10‑K20 use cases.

• Full-radius grooving precision: Specifically designed for full-radius grooves on small-diameter parts, achieving clean radii with a 7.1 mm minimum diameter, 1 mm groove width, and a 22 mm reach for tight pockets.
• Dual PVD coating options for durability: Choose BXC TiN for low-speed stainless steel work or BMK’s triple-coated sub-micron structure for high heat resistance, giving you longer tool life and consistent finishes.
• Versatile carbide for turning and grooving: Solid carbide construction delivers reliable performance in general turning and grooving tasks, reducing downtime and ensuring steady, repeatable results across materials.

This tool helps you complete precise grooves and transitions in tight spaces while maintaining consistent quality and finish. Its compact reach, durable carbide build, and coating options work together to improve workflow, reduce setup time, and deliver dependable results across everyday turning and grooving jobs.
