The Carmex Mini Carbide Chamfer Cutter 90° Long Reach is a compact, high-precision tool designed for chamfering, deburring, and countersinking in tight spaces. It’s ideal for metalworking pros and DIY enthusiasts who need clean, consistent edges in hard-to-reach areas.

  • 90° chamfer angle: Delivers precise, perpendicular edges for accurate mating surfaces and smooth deburrs.
  • Long reach design: 51 mm overall length to access recessed features, deep pockets, and cramped workzones.
  • 5 mm shank diameter with a 20 mm cutting length: A compact profile that fits common 5 mm collets while providing adequate cutting depth.
  • Carbide construction: Durable cutting edge that maintains sharpness and delivers consistent results across multiple passes.
  • Versatile cutting tip: Well suited for chamfering, deburring, and countersinking on metal and hard plastics.
  • Compatibility: Designed to work with standard rotary tools that accept 5 mm shanks for easy integration into existing setups.

This cutter helps you produce professional, finished edges with less tool swapping in confined work areas. The carbide tip maintains performance over time, while the long reach reduces handling interruptions, making it a reliable choice for precise edge preparation in tight spots.
