Description

The Carmex Carbide Tiny Tool — Face Grooving with Chip Breaker (MFL-C, BMK Grade) is a solid carbide bar engineered specifically for face grooving. With a left-hand cutting geometry, a 5 mm minimum diameter and a 1.5 mm groove width, it delivers straight, consistent grooves and reliable performance across a wide range of materials, including stainless steels. Unlike rounded grooves from other bars, it yields precise profiles suitable for tight tolerances, while the integrated chip breaker helps manage chips for smoother cutting.

  • Straight Groove Geometry for Precise Profiles: These Tiny Tools bars are designed to create straight grooves, ensuring consistent width and a clean, flat bottom for reliable mating surfaces and reduced finishing time.
  • Coated Carbide Grades for Versatile Performance: Take advantage of two coating options tailored to material and speed: the BXC TiN-coated grade optimized for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), and the BMK sub-micron grade with triple PVD coating (ISO K10-K20) for exceptional heat resistance and smooth cutting across materials.
  • Fixed 5 mm Diameter and 1.5 mm Groove Width with Left-Hand Cut: The defined geometry and left-hand orientation deliver predictable tool engagement and repeatable results in standard face grooving setups.

With these features, you gain consistent groove quality, reduced secondary operations, and longer tool life thanks to the durable carbide and advanced coatings. The tool’s geometry supports reliable cutting across materials and speeds, helping you streamline setup, minimize downtime, and achieve repeatable, high-quality grooves in production environments.
