The tip is manufactured from submicron solid carbide in IC908 grade and features a PVD-applied TiAlN finish that improves wear resistance and extends tool life in demanding cuts. The cutting diameter is 0.311 inches with a functional length of 0.111 inches and a 134-degree included angle at the drill point. A self-centering point geometry and web-thinned design reduce entry thrust and improve hole location accuracy without a pilot operation. Two slow-spiral flutes handle chip evacuation in deep-hole drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is intended for production drilling operations in steel and cast iron as primary workpiece materials, with rated capability in stainless steel, super-alloys, titanium, and hard materials as secondary applications. The HCP-IQ replaceable-tip system allows tip replacement at the machine without disturbing the shank body, reducing tooling changeover time in CNC turning centers, machining centers, and dedicated drilling cells. It is suited for job shops and production facilities running high-volume hole programs where consistent diameter control and tip economy are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 submicron solid carbide tip grade for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating improves heat resistance and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003eSelf-centering 134-degree point geometry eliminates need for a pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design reduces axial thrust at entry\u003c\/li\u003e\n  \u003cli\u003eSlow-spiral two-flute configuration optimized for deep-hole chip evacuation\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip interface (HCP-IQ) allows fast tip swaps without removing the drill body\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the ISCAR HCP-IQ replaceable-tip drill body system, Insert Seat Size 7.

Power down and lock out the machine spindle before seating or removing the tip. Ensure the insert seat is clean and free of chips before engaging the tip to prevent seating errors that affect runout. Follow the tool body manufacturer torque and engagement guidelines; do not use impact tools on the tip interface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.311 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.60 mm (0.181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 134 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HCP-IQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: HCP 079-IQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron (ISO P, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Super-alloys, Titanium, Hard Material (ISO M, S, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3311612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737204031794,"sku":"3311612","price":245.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b3e605a469c8a0346f8b5eaf54da6ef_2b68625c-069a-4dee-9950-a79370dac327.jpg?v=1788785553","url":"https:\/\/voomisupply.com\/products\/iscar-3311612-replaceable-tip-drill-0-311-in-hcp-iq-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
