Carmex Carbide Tiny Tool is a compact solid carbide bar engineered for full-radius grooving and general turning tasks. It delivers precise, consistent grooves at tight diameters, featuring a 5.1 mm minimum diameter and 2 mm groove width, with a 15 mm reach to access narrow features.

This MKR K20-grade tool is available in two coated variants to suit different materials and speeds. BXC is a PVD TiN-coated grade designed for low cutting speeds and works well with a wide range of stainless steels (ISO P30–P50 / K25–K40). BMK is a sub-micron grade with an advanced PVD triple coating (ISO K10–K20), delivering extremely high heat resistance and a smooth cutting action across materials.

  • Two coated carbide grades for versatility: Choose BXC for efficient, low-speed grooving in stainless steels or BMK for high-heat, all-material performance with smooth cutting.
  • Precise full-radius grooving in a compact form: specifically designed to handle full-radius grooves at 5.1 mm minimum diameter and 2 mm groove width, with a 15 mm reach for tight-working environments.
  • Durable carbide with proven coating technology: solid carbide core paired with PVD coatings provides wear resistance and reliable cutting performance, reducing downtime across grooving and turning tasks.

This tool streamlines workfl ow by delivering clean groove finishes in tight spaces, lowering the need for tool changes, and providing repeatable results across turning and grooving operations. When you need precise grooves at small diameters with dependable life, the Carmex Tiny Tool offers consistent performance and confident, professional results.
