Carmex Carbide Tiny Tool - Full Radius Grooving - MKR - BXC Grade - 4.1mm Minimum Diameter x 1.5mm Groove Width - 10mm Reach

The Carmex Carbide Tiny Tool MKR is a compact, solid carbide grooving tool designed to deliver precise full-radius grooves on small-diameter workpieces. With a 4.1 mm minimum diameter and a 1.5 mm groove width, plus a 10 mm reach, it fits into tight spaces for accurate internal and external grooving and can also handle general turning tasks with consistent results.

This tool line is offered in two coated carbide grades to match different materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), while BMK is a sub-micron grade with a triple PVD coating that provides very high heat resistance and smooth cutting across a broad material range (ISO K10-K20). This versatility helps you optimize tool life and finish on demanding jobs.

• Full-radius grooving in a compact form: Achieve precise, consistent full-radius grooves on small-diameter parts with a narrow 1.5 mm groove width and a 10 mm reach, all in a single setup.
• Two coated grades for broad material coverage: Choose BXC for stainless steels at lower speeds or BMK for higher heat tolerance and smoother cuts across a variety of materials, thanks to advanced PVD coatings.
• Durable carbide for reliable performance: Solid carbide construction delivers long tool life and stable cutting performance in turning and grooving, reducing downtime and rework.

This tiny yet capable tool helps you complete intricate grooves faster, maintain tight tolerances, and achieve better surface finishes, all while keeping setup straightforward in busy shop environments.
