Description

The Carmex Carbide Tiny Tool is a profiling and boring cutting solution designed for small-diameter work. Its compact carbide design, paired with an internal coolant bore and an advanced chip breaker, delivers efficient chip evacuation and maintains accuracy in tight pockets.

Optimized for stainless steels, super alloys, and other chip-prone materials, this tool is ideal for engineers, shop-floor technicians, and hobbyists who demand dependable performance in demanding applications. Built with TNX-grade carbide, it balances hardness and toughness for consistent results across jobs.

  • Small-diameter profiling and boring geometry: 4.1 mm minimum diameter, 0.2 mm reach, and an R0.4 corner radius enable precise contours and bore features in tight workzones with stable guidance and smooth finishes.
  • Advanced chip breaker with internal coolant bore: Effective chip control and enhanced evacuation reduce curling and heat build-up, helping maintain dimensional accuracy and extend cutting life.
  • TNX-grade carbide for tough materials: Formulated to tackle stainless steels and super alloys, delivering reliable performance and consistent finishes under demanding conditions.

This tool supports faster, more reliable profiling and boring in restricted spaces while maintaining quality across difficult materials. The combination of a tight geometry, intelligent chip control, and the resilient TNX carbide helps you improve throughput, reduce downtime, and achieve repeatable, high-quality results in every job.
