This advanced composition provides superior heat and wear resistance, allowing them to cut through hard metals like stainless steel, cast iron, and titanium alloy up to 12x longer than standard HSS bits.\u003c\/li\u003e\n\u003cli\u003ePrecision 135° Split Point: Features a self-centering 135-degree split point tip that penetrates hard materials immediately with less pressure. This design eliminates \"walking\" or wandering on the surface, ensuring a precise start without the need for a center punch or pilot hole.\u003c\/li\u003e\n\u003cli\u003eFully Ground for Efficiency: Unlike roll-forged alternatives, these bits are fully ground from solid hardened steel. This precise manufacturing process ensures accurate diameter concentricity and sharper cutting edges. The precision-ground dual flutes provide smooth, efficient chip removal to prevent overheating.\u003c\/li\u003e\n\u003cli\u003e13-Piece Metric Size Range: A comprehensive set covering common metric sizes for tapping and general drilling: 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, and 6.5mm. Includes specific sizes often required for rivets or pre-threading holes (e.g., 3.2mm, 4.8mm).\u003c\/li\u003e\n\u003cli\u003eProfessional Metal Index Case: Housed in a durable, heavy-duty red metal index case rather than plastic. The case features a clearly labeled metal holder that tilts out for easy access and organization, protecting the bits from damage during transport and storage in rough workshop environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 5% Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter:\u003c\/strong\u003e 1.5 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Type:\u003c\/strong\u003e Bronze Oxide\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":"HYMNORQ","offers":[{"title":"Default Title","offer_id":50633124151515,"sku":"B08L3HPSQ2-style-13pcs-red-case","price":22.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/0917\/1675\/files\/515Lyl31A8S_b454dbf0-d919-412d-8352-273aa42710e4.jpg?v=1791904119","url":"https:\/\/spruvexa.com\/products\/13-piece-m35-cobalt-steel-drill-bit-set-metric-1-5mm-6-5mm-style-13pcs-red-case-2","provider":" Spruvexa","version":"1.0","type":"link"}
