The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide cutting bar designed for precise boring and versatile enough for general turning tasks. With a 5.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 nose, it excels in tight bores and space-constrained setups, making it a reliable companion for machine shops, engineers, and hobbyists alike.

This product line offers two coating grades to match your application. BMK is a sub-micron grade with an advanced PVD triple coating (ISO K10–K20), delivering extremely high heat resistance and smooth cutting for maximum performance across materials. BXC is a TiN-coated grade optimized for low cutting speeds, ideal for a wide range of stainless steels (ISO P30–P50 / K25–K40) and demanding turning tasks.

• BMK Sub-Micron Grade with PVD Triple Coating: Delivers exceptional heat resistance and smooth cutting for reliable performance across a broad material range, making it a robust choice for demanding boring and turning jobs.
• BXC TiN Coated Grade for Low Cutting Speeds: Optimized for stainless steels and slower speeds, reducing wear and extending tool life while maintaining consistent finishes.
• Compact Left-Hand Boring Bar: 5.1 mm Ø, 22 mm Reach, R0.2 Nose: Designed for tight bores and space-limited operations, delivering precise geometry and stable cutting in challenging setups.

By choosing the Carmex Tiny Tool boring bar, you gain a compact, reliable solution that streamlines small-diameter boring and turning tasks. The dual-grade coatings provide flexibility to match your material and speed requirements, while the carbide substrate and precise geometry support smoother cuts, longer tool life, and repeatable finishes. This translates to reduced downtime, fewer tool changes, and consistent results across jobs.
