Description

The Carmex Carbide Tiny Tool is a compact, solid carbide bar designed for precise full-radius grooving on small-diameter workpieces. Its left-hand 15 mm reach, 5.1 mm minimum diameter, and 1.5 mm groove width deliver consistent groove profiles in tight spaces, making it ideal for precision turning, micro-machining, and fixture-friendly setups.

In addition to grooving, this tool line is well-suited for general turning tasks. It uses a K20-grade carbide core and offers coated grades to match different materials and speeds. BXC TiN-coated variants are optimized for low cutting speeds and work well with stainless steels (ISO P30-P50 / K25-K40). BMK-grade tools feature a sub-micron core with a triple PVD coating for very high heat resistance and a smooth cutting action. This combination provides versatile performance across common materials.

  • Full-radius grooving precision: Engineered to maintain accurate, repeatable groove geometry with a 1.5 mm groove width on a 5.1 mm minimum diameter, delivering consistent results in tight spaces.
  • Coated grades for versatility: BXC TiN coating offers reduced friction at low speeds (great for stainless steels), while BMK’s triple PVD coating provides superior heat resistance and a smooth cut for demanding materials.
  • Robust carbide with targeted reach: Solid carbide construction and a 15 mm left-hand reach enable stable cuts and access to recessed grooves, enhancing tool life and reliability in challenging turning and grooving tasks.

This combination of precise geometry, adaptable coating options, and a dedicated reach helps you finish grooves cleanly and efficiently, reduces setup time, and delivers dependable performance across a variety of materials and applications.
