The Carmex Carbide Tiny Tool is a compact boring bar crafted from solid carbide. Although designed primarily for boring applications, it also handles general turning jobs, making it a versatile choice for engineers, machinists, and hobbyists alike. With a 5.1 mm minimum diameter, a 40 mm reach, and a 0.2 mm nose radius (R0.2), this tool reaches tight features while delivering precise, clean cuts.

Two high-performance grades give you the right balance of speed, heat resistance, and finish for a wide range of materials. BXC is a PVD TiN-coated grade designed for low cutting speeds and works well with a broad range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with an advanced PVD triple coating, offering extremely high heat resistance for maximum performance and a smooth cutting operation, making it a capable general-purpose option for all materials.

• Compact precision for tight bores: With a 5.1 mm minimum diameter, 40 mm reach, and R0.2 nose radius, this tiny boring bar accesses confined features while preserving accurate tolerances and clean surfaces.
• Two grade options for material versatility: Choose BXC for low-speed stainless steel work with TiN coating, or BMK for high-heat, smooth-cutting performance with triple PVD coating—each grade optimized for different speeds and materials.
• Rugged carbide construction for durability: Solid carbide ensures rigidity and wear resistance, delivering consistent results across boring and turning tasks with reduced downtime and predictable finishes.

Designed to streamline setups and enhance workflow, the Carmex Carbide Tiny Tool delivers reliable, repeatable results across a range of jobs—from precision bores in stainless steel to general turning operations. Its compact form, coating options, and durable construction help extend tool life, minimize changes, and achieve dependable finishes on demanding projects.
