With a 5.1 mm minimum diameter, a 15 mm reach, and a left-hand orientation with an R0.2 corner, it delivers precise, repeatable bore quality in tight spaces. Built for tough shop environments, this tool ensures consistent results across a range of materials.\n\u003c\/p\u003e \u003cp\u003e\nThis tool line offers two coatings to match your material and speed needs. The BXC grade uses a PVD TiN coating optimized for low cutting speeds and performs well with stainless steels (ISO ranges P30–P50 \/ K25–K40). The BMK grade features a sub‑micron carbide core with an advanced PVD triple coating for extremely high heat resistance and smooth cutting across many materials, making it a versatile choice for general-purpose use.\n\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCoating options for versatile material performance\u003c\/b\u003e: Choose BXC TiN for efficient cutting at lower speeds on stainless steels, or BMK’s triple PVD coating for broad material compatibility and sustained performance across a wide range of jobs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh-heat resilience for longer tool life\u003c\/b\u003e: BMK’s sub‑micron grade with triple coating delivers excellent heat resistance, helping maintain sharpness and consistent cuts during demanding operations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompact geometry for tiny bores\u003c\/b\u003e: With a 5.1 mm minimum diameter, 15 mm reach, and a precise R0.2 corner in a left‑hand configuration, this boring bar excels at tight tolerances and clean finishes in confined spaces.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\nDesigned to fit both production and repair workflows, the Carmex Tiny Tool helps you achieve reliable bore quality, reduce downtime, and keep projects moving—from prototype runs to volume manufacturing. Its hardened carbide construction, combined with purpose‑built coatings, provides steady performance and predictable results across materials, so you can trust it to deliver consistent finishes and repeatable outcomes every time.\n\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carmex","offers":[{"title":"Default Title","offer_id":43432543617102,"sku":"MTL5R0.2L15K20","price":22.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/3747\/4382\/files\/MTR-K20_8c6b3606-aad4-419e-8a58-ba5d69be5f12.png?v=1770583036","url":"https:\/\/www.protool-ltd.co.uk\/products\/mtl5r0-2l15k20","provider":"Protool Precision Tools","version":"1.0","type":"link"}
