The Carmex Carbide Tiny Tool is a solid carbide boring bar built for tight bores and general turning. Its compact 4.1 mm minimum diameter, 15 mm reach, and R0.1 nose radius let you access confined features with precise control. This tool is ideal for machinists, engineers, hobbyists, and shop floor technicians who demand reliable performance in small-diameter parts.

The BMK-grade variant uses sub-micron carbide with an advanced PVD triple coating to deliver outstanding heat resistance and smooth cutting across a wide range of materials. For stainless steels and other demanding applications, the BXC TiN-coated option from the same family provides excellent wear resistance at lower cutting speeds.

• BMK Sub-Micron Grade with Triple PVD Coating: Extreme heat resistance (ISO K10-K20) enables maximum performance and a consistently smooth cut, helping you maintain pass-through quality and tool life across materials.
• BXC TiN Coated Grade for Stainless Steel: PVD TiN coating supports low cutting speeds while delivering reliable wear resistance on stainless steels (ISO P30-P50 / K25-K40).
• Compact Geometry: 4.1 mm Ø, 15 mm Reach, R0.1: Allows access to tight bores and deep pockets with stable, precise cuts and minimal tool deflection.

Designed to simplify setups, deliver repeatable internal finishes, and extend tool life, this Carmex Tiny Tool helps streamline boring and general turning workflows from prototype runs to production parts.
