They are particularly suitable for machining soft to medium-hardness metals such as low-carbon steel, alloy steel, aluminum alloy, and copper.\u003c\/li\u003e\n\u003cli\u003e3- APPLICATION - For precision drilling in soft metals, hardwoods, composite boards, and carved components, these bits efficiently process dense woods like rosewood and teak. The cutting edges maintain exceptional sharpness even at high RPM, making them perfect for detailed craft carving, mortise-and-tenon joinery, and thin wood sheet drilling - the ultimate tool for woodworking DIY, furniture manufacturing, and artistic carving applications.\u003c\/li\u003e\n\u003cli\u003e4- HIGH EFFICIENCY - 4341 high-speed steel twist drills strike an excellent balance between performance and cost, making them one of the most cost-effective high-speed steel options available. Under normal machining conditions, they deliver stable and reliable drilling performance while maintaining a long service life.\u003c\/li\u003e\n\u003cli\u003e5- TAKE NOTICE OF - Position the twist drill perpendicular (90°) to the workpiece surface. Begin drilling at low RPM (500-800) to establish a small hole, then adjust speed based on material: higher for wood, lower for metals. Use cutting fluid to effectively reduce temperature, minimize wear, and extend drill bit life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter:\u003c\/strong\u003e 1.61 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Type:\u003c\/strong\u003e Titanium Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type:\u003c\/strong\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Angle String:\u003c\/strong\u003e 135 degrees\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kozelo","offers":[{"title":"Default Title","offer_id":50541733871835,"sku":"B0G39S1G2M-size-52","price":9.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/0917\/1675\/files\/41FhKgiJ5sL.jpg?v=1790811431","url":"https:\/\/spruvexa.com\/products\/5pcs-micro-drill-bit-52-diameter-1-613mm-4341-hss-for-soft-metal-size-52","provider":" Spruvexa","version":"1.0","type":"link"}
