{"product_id":"mtr1-5r0l6k20","title":"Carmex Carbide Tiny Tool - Boring Bar - MTR - K20 Grade - 1.5mm Minimum Diameter x 6mm Reach x R0","description":"\u003cdiv\u003e\n\u003cp\u003e\nCarmex Carbide Tiny Tool is a precision boring bar built from solid carbide, designed for micro-machining where space is tight and accuracy matters. With a 1.5 mm minimum diameter, a 6 mm reach, and an R0 tip, this tiny tool excels at boring small-diameter holes and performing delicate finishing passes in compact workpieces while delivering stable, repeatable results.\n\u003c\/p\u003e \u003cp\u003e\nTwo coated grades are available to match material and cutting conditions. The BXC option uses a PVD TiN coating for low cutting speeds and performs well with a wide range of stainless steels (ISO P30-P50 \/ K25-K40). The BMK grade features a sub-micron core with an advanced PVD triple coating for extremely high heat resistance and smooth cutting, providing reliable performance across a broad material spectrum (ISO K10-K20) and general-purpose capability for all materials.\n\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMicro-diameter, long-reach boring capability\u003c\/b\u003e: Access tight bores and internal features with a 1.5 mm minimum diameter and a 6 mm reach, enabling precise micro-machining in small parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTwo high-performance coatings\u003c\/b\u003e: Choose BXC TiN for low-speed stainless steel work or BMK’s triple coating for high heat resistance and smooth cutting across materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSolid carbide construction with R0 tip\u003c\/b\u003e: Delivers consistent, clean entry cuts and long tool life in demanding boring and turning tasks.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\nThese characteristics help you reduce setup time, minimize downtime, and achieve consistent hole quality and surface finish across stainless steels and other materials.
