TiN-coated cutting tools outlast those which are not coated. Workability is also improved because swarf and chips are less likely to adhere to the cutting surface.\u003cbr\u003e^^ When drilling stainless steel use low speed, high pressure, and cutting fluid. Otherwise, the stainless steel will overheat causing work hardening which will damage the step drill.\u003c\/p\u003e\u003cp\u003e\u0026gt; Also known as a universal drill, cone drill, or Uni-bit.\u003cbr\u003e\u0026gt; Use cutting fluid to increase tool life especially with hard materials like stainless.\u003c\/p\u003e","brand":"AliExpress - CN","offers":[{"title":"Default Title","offer_id":45131080728629,"sku":"T30204","price":29.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/8621\/files\/Desic-Step-Drill-Set-3-Pieces-Spiral-Flute-TiN-Coated-Hex-Shank-4-32mm-A.jpg?v=1777000533","url":"https:\/\/testntools.co.nz\/products\/desic-step-drill-set-3-pieces-spiral-flute-tin-coated-hex-shank-4-32mm","provider":"Testntools","version":"1.0","type":"link"}
