This results in a significantly longer tool life compared to standard titanium nitride or oxide coatings.\u003c\/li\u003e\n\u003cli\u003e🎯 【Triple-Flute Design: Smother Finish, Faster Drilling, Pinpoint Accuracy】 The innovative three-flute geometry provides three key advantages over conventional two-flute bits: superior hole roundness and wall finish, approximately 40% improved chip ejection for cooler operation, and enhanced drilling accuracy with reduced bit walk. For optimal performance, recommended for standard depth of cut applications.\u003c\/li\u003e\n\u003cli\u003e🛠️【Three-Flat Shank for Maximum Grip \u0026amp; Zero Slip】 The precision-machined three-flat shank ensures a complete lock in the drill chuck, eliminating spin-out even under high-torque conditions from impact drivers and heavy-duty drills. This guarantees full power transfer and safer operation.\u003c\/li\u003e\n\u003cli\u003e📦 【Comprehensive 21-Piece Professional Set】 This ready-to-use set includes 21 essential sizes from fine 1\/16\" to heavy-duty 1\/2\", covering over 90% of common metal drilling tasks. *Note: Bits 1\/16\" through 7\/64\" feature a precision two-flute design for delicate work, while sizes 3\/32\" and up utilize the performance triple-flute design.*\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eOverview\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial : High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003eFinish Type : Titanium Aluminum Nitride\u003c\/li\u003e\n\u003cli\u003eShank Type : 3-Flat,Round\u003c\/li\u003e\n\u003cli\u003eCutting Angle String : 135 Degrees\u003c\/li\u003e\n\u003cli\u003eBrand : Crosstar\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Crosstar","offers":[{"title":"Default Title","offer_id":53167499378997,"sku":"B0FBRY3KCS","price":82.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/5698\/4373\/files\/81MyDbJMKIL._AC_SX679_PIbundle-21_TopRight_0_0_SH20.jpg?v=1784329826","url":"https:\/\/www.mybellabloom.com\/products\/b0fbry3kcs","provider":"Bella Bloom","version":"1.0","type":"link"}
