Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for small-diameter work and tight pockets. With a 1 mm minimum diameter, a 6 mm reach, and a precise R0.05 nose, it delivers accurate, repeatable holes in micro-boring and light turning applications. Built for reliability, this BMK-grade option is engineered to perform in demanding shop conditions and across a range of materials.

• BMK-grade carbide with advanced PVD triple coating: Sub-micron carbide paired with a triple PVD coating provides exceptional heat resistance and a smooth cutting action, enabling consistent results across a wide material range, including stainless steels.
• Ultra-compact micro-diameter with 6 mm reach and R0.05 nose: Perfect for miniature bores and tight spaces, the 1 mm minimum diameter and defined 0.05 mm radius help maintain rigidity while delivering precise hole size and clean finishes.
• Durable, versatile boring bar for long tool life: Built on a solid carbide core with protective coating to resist wear at high temperatures, supporting more parts between tool changes with reliable, repeatable performance.

This Tiny Tool streamlines small-diameter projects by delivering consistent geometry, smooth finishes, and durable performance in a single, easy-to-integrate tool. It supports efficient boring and turning workflows, helps reduce downtime from tool changes, and provides confidence when working with a broad range of materials—from stainless steels to other tough alloys.
