Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 3.1mm Minimum Diameter x 10mm Reach x R0.2

Carmex Carbide Tiny Tool is a precision solid carbide boring bar designed for tight bores and small-diameter turning. With a 3.1 mm minimum diameter, a 10 mm reach, and a concise R0.2 nose radius, it fits into confined cavities while delivering clean, accurate cuts. This tool is ideal for engineers, machinists, and hobbyists who need reliable performance in compact spaces.

Available in two high-performance coating grades, BMK and BXC, the BMK grade provides exceptional heat resistance and smooth cutting for general-purpose turning across many materials. The BXC grade features a PVD TiN coating, optimized for low cutting speeds and stainless steels, expanding versatility for stainless-heavy work and slow-feeding applications.

• Small-diameter bore capability: Fits into tight bores with a 3.1 mm minimum diameter and 10 mm reach, plus a 0.2 mm nose radius for precise, controlled cuts in confined spaces.
• BMK-grade with triple coating: Sub-micron carbide with an advanced PVD triple coating delivers extremely high heat resistance and smooth cutting for reliable performance across materials (ISO K10–K20).
• BXC TiN-coated option for stainless steels: Low cutting speeds and TiN coating reduce friction and wear, extending tool life when machining stainless steels (ISO P30–P50 / K25–K40).

This tiny carbide tool helps you streamline boring and turning tasks. The compact form maximizes access to tight features, while the BMK-grade coating combination minimizes heat buildup and chatter, promoting longer tool life and consistent dimensions. When your work requires stainless steel or slow feeds, the BXC TiN-coated option delivers durable performance with reduced friction, helping you finish parts faster with smooth surface finishes. Overall, Carmex Tiny Tool delivers dependable, repeatable results that keep your workflow moving and your machined parts right on spec.
