{"product_id":"mtl7r0-2l30bmk","title":"Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK 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 boring and light turning tasks. With a 7.1 mm minimum diameter, a 30 mm reach, and a left-hand cutting geometry with a tight R0.2 corner, it helps you reach tight cavities and produce accurate holes consistently.\n\u003c\/p\u003e \u003cp\u003e\nTwo coating grades tailor performance to material and speed. The BXC grade uses a PVD TiN coating optimized for stainless steels at lower cutting speeds (ISO P30–P50 \/ K25–K40), while BMK is a sub-micron grade with a triple PVD coating that delivers excellent heat resistance and smooth cutting across a broad range of materials. This combination makes the tool suitable for general purpose use as well as demanding applications.\n\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eVersatile coating options for stainless and general materials\u003c\/b\u003e: Choose BXC for stainless steels at lower speeds or BMK for high-heat, broad-material performance, providing the right balance of wear resistance and cutting efficiency for each job.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSlim, precise geometry for tight bores\u003c\/b\u003e: 7.1 mm minimum diameter, 30 mm reach, left-hand orientation, and a tight R0.2 corner ensure clean entry and exit in confined cavities with consistent hole sizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRigid carbide durability for long tool life\u003c\/b\u003e: Solid carbide construction paired with advanced coatings delivers stiffness, wear resistance, and reliable, repeatable results across multiple cycles.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\nThis tiny boring bar helps you complete internal boring and light turning tasks with confidence, delivering accurate hole diameters and smooth finished surfaces. The coating options let you tailor performance to stainless steels or general materials, reducing heat buildup and extending tool life. The rigid carbide core and optimized geometry minimize chatter and downtime, speeding setups and improving throughput across production runs.\n\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carmex","offers":[{"title":"Default Title","offer_id":43432554037326,"sku":"MTL7R0.2L30BMK","price":35.97,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/3747\/4382\/files\/MTR_BMK_6dcbf089-49e1-4072-9296-c85925019693.png?v=1770583335","url":"https:\/\/www.protool-ltd.co.uk\/products\/mtl7r0-2l30bmk","provider":"Protool Precision Tools","version":"1.0","type":"link"}
