Description

The Carmex Carbide Tiny Tool is a solid carbide grooving bar designed for full-radius grooves and general turning. Its compact, rigid design makes it a dependable choice for engineers, machinists, and hobbyists working in tight spaces or on stainless steels.

This MKR family leverages two coating options to optimize performance across materials and speeds: BXC TiN coating for low cutting speeds on stainless steel, and BMK with sub-micron grade and a triple PVD coating for exceptional heat resistance and smooth cutting. With a 7.1 mm minimum diameter, a 1 mm groove width, and a 30 mm reach, it handles deep, accurate grooves without frequent tool changes.

  • Full-Radius Grooving Capability: Delivers precise full-radius grooves with a 1 mm groove width and 30 mm reach, producing consistent geometry and a clean surface finish in tight or hard-to-reach areas.
  • Coating Options for Versatility: Choose BXC TiN for efficient, wear-resistant performance at low speeds on stainless steel, or BMK’s sub-micron, triple-coated durability for high-heat conditions and smoother cutting across a broad material range.
  • Rigid, Compact Carbide Construction: Built from solid carbide with a 7.1 mm minimum diameter and a 30 mm reach, delivering rigidity and long tool life for reliable results in general turning and demanding grooving tasks.

Designed to help you finish grooves faster and with greater precision, the Carmex Tiny Tool supports consistent radii, better surface quality, and fewer interruptions in production. The dual coating options let you tailor performance to your material and process, while the compact, durable carbide body ensures dependable results across a wide range of turning operations.
