Carmex Carbide Tiny Tool is a compact, left-hand boring bar designed for precise internal boring and versatile turning in tight spaces. With a 1 mm minimum bore diameter, a 4 mm reach, and a precise R0.05 corner radius, it delivers clean, consistent holes in small parts while fitting into constrained setups.
This tool uses solid carbide and is offered in TNX Grade with two coating options to suit different materials and speeds. The BXC variant features a PVD TiN coating for reliable cutting at lower speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK variant is a sub-micron grade with an advanced PVD triple coating, delivering excellent heat resistance for maximum performance and smooth operation across materials. This makes the tiny tool versatile for boring and general turning tasks.
- Ultra-compact boring capability: 1 mm minimum bore, 4 mm reach, and a 0.05 mm radius produce precise, smooth holes in tight workpieces, with a left-hand orientation that suits specific setups.
- Two high-performance TNX-grade coatings: BXC TiN coating enables efficient cutting at low speeds on stainless steels; BMK’s triple-coated sub-micron grade offers exceptional heat resistance and consistently smooth cuts across a wide material range.
- Solid carbide core for durability and consistency: Rugged carbide construction and precise geometry deliver repeatable results, reduced downtime, and dependable performance in boring and turning operations.
This combination helps you achieve tighter tolerances, longer tool life, and faster, more predictable production. Whether you’re producing small automotive components, precision housings, or intricate fixtures, Carmex Tiny Tool provides reliable performance, straightforward setup, and consistent finishes you can trust.
