The Carmex Carbide Tiny Tool - Boring Bar in MTL is a compact, solid carbide bar designed for precise boring and general turning in tight spaces. With a 3.1 mm minimum diameter, 15 mm reach, and an R0.2 left-hand nose, it’s engineered to access small bores and deliver clean, accurate cuts. This BXC Grade variant features a TiN coating formulated for low cutting speeds and improved performance when working with stainless steels, making it a reliable choice for finish-critical parts and confined setups.

• Ultra-compact size for tight bores: 3.1 mm minimum diameter with a 15 mm reach lets you access narrow cavities and start cuts precisely in restricted spaces.
• BXC TiN-coated grade for stainless steels: Low cutting speeds with reduced friction and wear resistance deliver smoother cuts and longer tool life on stainless materials.
• Left-hand R0.2 nose for stable boring: Optimized geometry provides consistent entry and bore quality on left-handed setups, helping minimize chatter and improve finish.

Designed for reliability in demanding shops, this carbide boring bar combines rigid tooling with a coating that protects cutting edges at lower speeds. It supports repeatable, high-quality bore finishes, reduces tool changes, and enhances overall workflow when working with small-diameter features and tight tolerances.
