Built from powdered metal and finished with a multi-layer nano-FIREX coating, it delivers extended tool life in demanding production environments. The bit features a 130-degree cone relief point with web thinning for reduced thrust and cleaner entry, and a parabolic flute geometry that promotes fast chip evacuation. Overall length is 1.3386 inches (34.00 mm), with a 0.0635-inch decimal diameter and an h8 shank diameter tolerance for consistent chuck fit. Licensed HVAC techs, machinists, and tool-room professionals reach for this bit when cycle time and hole quality matter.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized at wire gauge 52 (0.0635 inches) and is suited for precision drilling operations in ferrous materials including steel and cast iron. Its stub-length body reduces deflection in short-reach applications such as CNC machining centers, turret lathes, and screw machines. The straight cylindrical shank accepts standard drill chucks and collets. The parabolic fast-spiral flute design clears chips efficiently at higher feed rates, making it a practical choice for production runs where consistent hole geometry and tight tolerances are required. Conforms to DIN 1897 specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMulti-layer nano-FIREX coating for extended wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree cone relief point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eParabolic fast-spiral flutes for aggressive chip evacuation at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eStub length (1.3386 inches OAL) minimizes deflection in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eh8 shank diameter tolerance ensures repeatable fit in precision chucks and collets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1897 standard; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel and cast iron workpieces.

Secure the shank fully in a calibrated chuck or collet and confirm runout before beginning a cut. Power down and lock out the machine spindle before changing or inspecting the bit. Do not exceed the recommended maximum drilling depth of 0.2990 inches (7.59 mm) per pass for this stub-length geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.3386 inches (34.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.2990 inches (7.59 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0634 inches (1.61 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Multi-layer nano-FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005150016100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743225151794,"sku":"9005150016100","price":171.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d0a64a9a0c8bb720105d64f4a624ae.jpg?v=1788844157","url":"https:\/\/voomisupply.com\/products\/guhring-9005150016100-drill-bit-size-52-130-deg-stub","provider":"Voomi Supply","version":"1.0","type":"link"}
