HSS is suitable for mild steels, free-machining materials, aluminum and other non-ferrous metals, wood, and plastic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What point angle do these drill bits use, and why does it matter?\u003c\/strong\u003e\u003cbr\u003eA: These bits feature a 118° conventional point, which is the standard geometry for mild steels and free-machining materials, providing rapid penetration in everyday general purpose drilling applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the black oxide surface treatment do?\u003c\/strong\u003e\u003cbr\u003eA: The black oxide treatment reduces friction and heat damage, prevents chip welding, improves chip flow, and increases abrasion resistance — all of which contribute to longer tool life compared to uncoated bright-finish drills on low to medium tensile strength materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What size range does the 29-piece set cover?\u003c\/strong\u003e\u003cbr\u003eA: The set covers 1\/16\" to 1\/2\" by 64ths, providing every fractional increment across that range in a single index.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are speed, feed, and lubrication important when using these drill bits?\u003c\/strong\u003e\u003cbr\u003eA: Yes — Drillco specifically notes that speed, feed, and lube are all critical to cutting tool performance with this series. Proper technique directly affects tool life and hole quality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: When should I choose a cobalt or TiN-coated drill instead of this HSS set?\u003c\/strong\u003e\u003cbr\u003eA: The 200A HSS set is optimized for low to medium tensile strength materials. For harder steels, stainless steel, or high-tensile-strength materials, Drillco offers cobalt (HSCo) and bronze surface treatment options in their lineup that are better suited to those demanding applications.\u003c\/p\u003e","brand":"Drillco","offers":[{"title":"Default Title","offer_id":67885658964142,"sku":"200A29","price":128.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0551\/8396\/6382\/files\/vohhqkfalonkarjz9yli.jpg?v=1793217507","url":"https:\/\/www.diamondtoolstore.com\/products\/200a-29-pc-set","provider":"Diamond Tool Store","version":"1.0","type":"link"}
