The Carmex Carbide Tiny Tool is a compact solid carbide grooving tool designed to deliver precise full-radius grooves on small-diameter workpieces. It’s ideal for engineers, buyers, tradespeople, hobbyists, and DIY makers who need reliable, repeatable grooves in tight spaces or during general turning tasks. This MKL tool features a K20 grade with a 7.1 mm minimum diameter and a 1 mm groove width, plus a 22 mm reach in a left-hand orientation. It’s offered in two high-performance coatings to suit different materials and speeds: BXC TiN for low cutting speeds on stainless steels and BMK with a sub-micron, triple PVD coating for enhanced heat resistance and smooth cutting across a wide range of materials.

  • Full-radius grooving at small diameters: Create precise, full-radius grooves starting at 7.1 mm diameter with a 1 mm groove width, ensuring clean, consistent profiles in tight spaces and during general turning.
  • Dual coating options for versatile performance: BXC TiN coating optimizes low-speed cutting on stainless steels (ISO P30-P50 / K25-K40), while BMK’s sub-micron, triple-PVD coating delivers exceptional heat resistance and smooth cutting across materials (ISO K10-K20).
  • Rigid, purpose-built geometry with practical reach: MKL form, left-hand orientation with a 22 mm reach provides stable cutting and easy access in confined setups, reducing setup time and improving overall reliability.

Designed for dependable, repeatable results, this tool helps you complete small-diameter grooving tasks faster with less risk of chatter or surface imperfections. The robust carbide core and optimized coatings minimize wear, extending tool life and delivering smooth, clean grooves across a range of materials, including stainless steels. Whether in a production cell or a one-off job, it supports consistent performance and confident, efficient machining.
