The black and gold surface treatment also makes it suitable for use on most materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does this set use a 135° split point instead of a conventional 118° point?\u003c\/strong\u003e\u003cbr\u003eA: The 135° split point is self-centering, which reduces walking on contact — especially important on curved or hard surfaces — and reduces the thrust required to drill. A conventional 118° point is better suited to mild steels and free-machining materials, while the 135° split point is preferred for harder materials and hand-drilling applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the advantage of the black and gold surface treatment over black oxide?\u003c\/strong\u003e\u003cbr\u003eA: The black and gold surface treatment provides better resistance to corrosion and breakage, increases lubricity, and reduces chipping and flaking compared to black oxide. Black oxide is generally suited to low to medium tensile strength materials, while black and gold is rated for most materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What sizes are included in the 800A25 set?\u003c\/strong\u003e\u003cbr\u003eA: The set includes 25 metric sizes from 1mm to 13mm in 0.5mm increments, covering the full range of common metric drill sizes in a single kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are speed, feed, and lubrication important when using these bits?\u003c\/strong\u003e\u003cbr\u003eA: Yes — DRILLCO specifically notes that speed, feed, and lube are all critical to cutting tool performance. Using appropriate cutting fluid and correct feed rates will extend bit life and improve hole quality, particularly in stainless steel and high strength materials.\u003c\/p\u003e","brand":"Drillco","offers":[{"title":"Default Title","offer_id":67894068805806,"sku":"800A25","price":211.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0551\/8396\/6382\/files\/lukqepwtktypebljdojz.jpg?v=1793276930","url":"https:\/\/www.diamondtoolstore.com\/products\/800a-25-pc-set","provider":"Diamond Tool Store","version":"1.0","type":"link"}
