{"product_id":"mtl7r0-2l30k20","title":"Carmex Carbide Tiny Tool - Boring Bar - MTL - K20 Grade - 7.1mm Minimum Diameter x 30mm Reach x R0.2 (Left Hand)","description":"\u003cdiv\u003e\n\u003cp\u003e\nThe Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precise internal work and small-diameter turning. With a 7.1 mm minimum diameter, a 30 mm reach, and a precise R0.2 corner radius, this tool delivers clean, accurate cuts in confined bores. It is part of a dual-grade coating family—BXC TiN-coated for low-speed cutting on stainless steels and BMK sub-micron grade with a triple PVD coating for high-heat performance. The left-hand version is tailored for common boring setups, helping you maintain consistent chip control and reliable results.\n\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCoating options engineered for different materials\u003c\/b\u003e: Choose between BXC TiN for low cutting speeds on a wide range of stainless steels (ISO P30-P50 \/ K25-K40) or BMK with a sub-micron grade and triple PVD coating for excellent heat resistance and smooth cutting (ISO K10-K20). This selection lets you maximize tool life and predictable results across varying jobs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSmall-diameter, deep-reach borings\u003c\/b\u003e: The 7.1 mm minimum diameter with a 30 mm reach enables you to access deep internal features and tight bores without sacrificing rigidity, delivering accurate profiles and minimized deflection in challenging workpieces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eLeft-hand geometry for efficient, stable cutting\u003c\/b\u003e: Designed for left-hand boring applications, the edge geometry and R0.2 corner radius promote steady cutting, reliable surface finishes, and consistent chip control across materials.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\nThis carbide tiny tool helps you complete precise internal passes faster, with consistent quality from start to finish. The dual-grade coating options let you tailor performance to your material and machine speed, while the compact size and left-hand geometry improve workflow in restricted setups. Whether you’re finishing delicate stainless parts or tackling general-purpose boring and turning, this tool offers dependable rigidity, longer tool life, and smoother cuts that reduce re-cutting and downtime.\n\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carmex","offers":[{"title":"Default Title","offer_id":43432554266702,"sku":"MTL7R0.2L30K20","price":31.58,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/3747\/4382\/files\/MTR-K20_ab96e447-dbb2-4cca-b0c9-004024cef1d5.png?v=1770583345","url":"https:\/\/www.protool-ltd.co.uk\/products\/mtl7r0-2l30k20","provider":"Protool Precision Tools","version":"1.0","type":"link"}
