The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision small-diameter work. While optimized for boring, it also handles general turning tasks, making it a versatile addition to any shop. With a compact 1.5 mm minimum diameter, 6 mm reach, and a left-hand orientation, it is ready for tight bores and delicate setups. This BMK-grade bar sits at the core of a versatile product line that also includes BXC TiN-coated options for specific material and speed needs.

• Compact, precision-sized boring bar: 1.5 mm minimum diameter and 6 mm reach deliver access to tight holes and hard-to-reach pockets, while the left-hand geometry helps maintain stable chip flow and consistent cuts in boring operations.
• BMK-grade coating for heat resistance: Sub-micron BMK with advanced PVD triple coating provides extremely high heat tolerance and smooth cutting, enabling reliable performance across a wide range of materials and cutting conditions.
• BXC TiN coating option for low-speed stainless steel work: TiN-coated grade optimized for low cutting speeds and stainless steels, reducing friction and wear to extend tool life and improve surface finish on stainless alloys (ISO P30-P50 / K25-K40 range).

This tiny carbide bar is built to deliver dependable, repeatable results in tight spaces. The combination of hard carbide substrate and advanced coatings helps maintain sharpness, reduce heat buildup, and minimize downtime caused by tool wear. Whether you’re tackling precision boring or general turning on challenging materials, this tool supports clean finishes, consistent dimensions, and efficient workflows, giving you confidence to finish jobs faster and with higher quality.
