The Carmex Carbide Tiny Tool - Boring Bar is a precision solid carbide bar designed for tight-diameter boring and general turning. With a 1.2 mm minimum diameter, 9 mm reach, and left-hand R0 geometry, it excels in confined bores and close-clearance work, delivering repeatable results.

This tool line offers two coating grades to match different materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with an advanced PVD triple coating, delivering extremely high heat resistance for maximum performance and smooth cutting. It serves as a general-purpose option for all materials.

• Ultra-compact boring bar geometry: 1.2 mm minimum diameter and 9 mm reach allow precise boring in tight spaces, with the left-hand R0 orientation matching common milling and turning setups.
• Dual-grade coating options for stainless and general materials: BXC TiN coating supports low-speed cuts on stainless steels (ISO P30-P50 / K25-K40); BMK triple-coated sub-micron grade provides superior heat resistance and smooth cutting across a wide material range (ISO K10-K20).
• Rugged carbide core for reliable, repeatable results: Solid carbide construction delivers rigidity and durability, with advanced coatings reducing wear and enabling steady finishes even on demanding jobs.

This tool is built to help you complete precise bore and turning tasks with confidence. By choosing the appropriate coating grade for the material and speed, you can streamline setups, achieve consistent surface finishes, and extend tool life in stainless steels and other alloys.
