With an 8.10 mm (0.3189 inch) diameter, a 140-degree split point, and a web-thinned SU point geometry, this bit delivers fast starts and precise hole entry with minimal thrust. The two-flute spiral design and through-coolant capability support efficient chip evacuation and heat management in deep-hole applications. At 89.00 mm overall length with a 10.00 mm straight-cylindrical shank, it is sized for use in CNC machining centers and screw machine setups. Licensed machinists and tool-and-die professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in cast iron and steel workpieces in production and job shop machining environments. The screw machine length body keeps the bit rigid in short-reach applications, reducing deflection during high-feed drilling cycles. The through-coolant channels allow coolant delivery directly to the cutting edge, making this bit well suited for stacked-part drilling, blind-hole work, and materials that generate significant heat at the cutting zone. The 3xD flute-to-diameter ratio supports drilling to a maximum depth of 44.00 mm in a single pass without peck cycles in most setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grain construction for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning for low-thrust, self-centering entry\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design channels fluid directly to the cutting edge for thermal control\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral geometry promotes positive chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 10.00 mm shank fits standard ER and hydraulic toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide screw machine drill for use in CNC machining centers, screw machines, and drill presses equipped with through-coolant spindle capability; primary workpiece materials are cast iron and steel per manufacturer specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per facility LOTO procedures. Ensure the shank is fully seated and clamped to the correct runout tolerance in the toolholder before operation. Through-coolant pressure should be set according to machine and toolholder specifications before initiating a drilling cycle. Inspect the cutting edges for chipping before each use, as carbide tooling is brittle and susceptible to damage from interrupted cuts or improper handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3189 inches (8.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.504 inches (89.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.850 inches (47.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.732 inches (44.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5510\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 9055100081000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731277938994,"sku":"9055100081000","price":260.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_c13d1e6b-9464-4ab0-a254-1905cb44b442.jpg?v=1788729171","url":"https:\/\/voomisupply.com\/products\/guhring-9055100081000-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
