Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 2.1mm Minimum Diameter x 10mm Reach x R0 (Left Hand)

The Carmex Carbide Tiny Tool is a compact boring bar crafted from solid carbide, built to excel in tiny bore work and precise turning. With a 2.1 mm minimum diameter, a 10 mm reach, and a left-hand R0 geometry, it reaches into confined spaces to produce accurate holes and clean finishes.

This tool line offers two coating grades to match material and speed needs: BXC TiN-coated grade for low cutting speeds and strong performance with stainless steels (ISO P30-P50 / K25-K40), and BMK—a sub-micron grade with advanced PVD triple coating that delivers very high heat resistance and smooth cutting across a wide range of materials (ISO K10-K20). These options make the tiny tool versatile for boring and general turning tasks.

• Two advanced coating grades for versatility: BXC TiN-coated grade is optimized for low-speed boring on stainless steels, while BMK's triple-coated sub-micron makeup provides excellent heat resistance and smooth cutting across many materials.
• Compact size for tiny bores: 2.1 mm minimum diameter with 10 mm reach and left-hand R0 geometry to access tight pockets and deliver accurate holes with minimal tool deflection.
• Durable, reliable carbide construction: Solid carbide core delivers long tool life and stable cutting performance under demanding conditions, helping maintain consistent hole quality and reduce downtime.

In practice, this tiny boring bar simplifies small-diameter machining by combining precise access with coating options that optimize wear, heat management, and finish quality. Whether you’re tackling stainless steel or a broad range of materials, you can rely on consistent performance from setup to part completion.
