Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 2.5mm Minimum Diameter x 15mm Reach x R0.1

The Carmex Carbide Tiny Tool is a precision boring bar designed for micro-machining where space is tight and tolerances matter. With a 2.5 mm minimum diameter, 15 mm reach, and a tip radius of R0.1, this solid carbide bar delivers rigid, accurate cuts in small bores and tight pockets. Designed for engineers, machinists, and hobbyists alike, it unlocks reliable turning and boring in challenging internal features. Two coating families offer tailored performance: BXC TiN-coated grade for stainless steels at low cutting speeds, and BMK sub‑micron grade with a PVD triple coating for exceptional heat resistance and smooth cutting across a wide range of materials.

• Rigid solid carbide construction: Provides stiffness and long tool life in tight bores, with a compact 2.5 mm diameter, 15 mm reach, and a precise R0.1 nose radius for accurate, repeatable cuts.
• BXC TiN-coated grade for stainless steel: Optimized for low cutting speeds to resist wear and deliver stable finishes on ISO P30–P50 / K25–K40 stainless steels.
• BMK sub‑micron with PVD triple coating: Delivers extremely high heat resistance and smooth cutting, making it versatile for a broad range of materials and everyday machining tasks.

This tiny boring bar helps you streamline setups, reduce tool changes, and maintain consistent results from first pass to finish. Its robust carbide core and thoughtful coatings support reliable performance, so you can focus on getting precise holes, clean faces, and dependable surface quality—every time.
