Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.1 (Left Hand)

The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide cutting tool designed for precision boring and small-diameter turning. With a minimum diameter of 6.1 mm and a reach of 22 mm, this left-hand boring bar is built for tight internal features, pockets, and finishing passes.

This BMK-grade version uses a sub-micron carbide with an advanced PVD triple coating to deliver extremely high heat resistance and smooth cutting across a wide range of materials. The product line also includes the BXC grade with a PVD TiN coating, optimized for low cutting speeds and stainless steels.

• Compact, precise boring geometry: Designed for tight internal work, it combines 6.1 mm minimum diameter, 22 mm reach, and a left-hand R0.1 nose to deliver controlled, repeatable cuts in confined bores and pockets.
• BMK Grade: Sub-micron carbide with triple PVD coating: Provides excellent heat resistance and a smooth cutting experience, enabling reliable performance across a wide range of materials.
• BXC Grade option for stainless steels: TiN-coated variant optimized for low cutting speeds, delivering dependable performance when machining stainless steels.

This tiny boring bar offers a reliable, versatile solution for internal machining and general turning tasks. The BMK-coated version supports consistent finishes and extended tool life under demanding conditions, while the BXC option broadens compatibility with stainless steels at lower speeds. Together, they help reduce tool changes, improve part consistency, and streamline workflows from setup to finish across diverse materials.
