Description

The Carmex Carbide Tiny Tool is a precision solid carbide bar engineered specifically for deep face grooving in tight spaces. With a 15 mm minimum diameter, a 4 mm groove width, and a 43 mm groove depth, this compact tool is built to deliver accurate, repeatable grooves in challenging parts.

Targeted at engineers, machinists, and hobbyists who work with stainless steels and other demanding materials, this BXC-grade tool uses a PVD TiN coating to support low cutting speeds, extend edge life, and deliver stable cutting in stainless steels. Note: This product line doesn’t contain bars for left-hand operations.

  • Deep face grooving geometry: Precisely engineered to cut deep grooves with consistent width and depth, enabling one-pass cycles and smooth surfaces in demanding materials.
  • PVD TiN-coated BXC grade for durability: TiN coating reduces wear at low cutting speeds, improves edge stability, and works well with stainless steels (ISO P30-P50 / K25-K40).
  • Rigid, compact form for tight spaces: The small 15 mm minimum diameter with a 4 mm groove width and 43 mm groove depth provides reach and rigidity in confined work areas, reducing tool changes and downtime.

Together, these features translate to reliable performance, consistent groove quality, and practical efficiency in everyday machining. Use the Carmex Tiny Tool for precise, deep grooves across a range of materials, with fewer passes and smoother finishes in tight setups.
