It carries a 0.2835 inch (7.20 mm) diameter and a 140-degree split point (SU type) that reduces walking and cutting thrust on entry. The web-thinned, parallel web geometry paired with two spiral flutes promotes efficient chip evacuation. Coolant-through capability keeps the cutting edge cool during deep-hole passes, extending tool life in continuous-duty applications. Machinists, toolroom technicians, and CNC operators install this bit in screw machine and machining center applications where tight diameter tolerances and consistent hole quality are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand cutting in cast iron and steel workpieces. The screw machine length body provides a compact, rigid profile that resists deflection in short-reach setups. With a straight-cylindrical shank of 8.00 mm (0.315 inches), it seats directly in standard ER collets, drill chucks, and hydraulic toolholders. The 3xD flute-to-diameter ratio and 41.00 mm flute length support drilling depths up to 38.00 mm (1.496 inches) per pass. Series 5510 is manufactured to DIN 6537K standards, making it a direct fit for metric-tolerance production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for elevated hardness and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point reduces entry thrust and eliminates center-punch marking on most steel grades\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for thermal management at high feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers cutting force and improves chip break geometry\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.006 to plus 0.021 mm supports close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537K specification for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces as stated in the product specification.

Seat the straight-cylindrical shank fully into the toolholder and torque the collet nut to the toolholder manufacturer specification before engaging the spindle. Verify coolant-through passages are clear and system pressure is set before drilling to prevent thermal damage to the carbide substrate. Carbide tooling is brittle — avoid side loading or prying the bit during extraction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2835 inches (7.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.110 inches (79.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.614 inches (41.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.496 inches (38.00 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 (split point)\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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, 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\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\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.006 to plus 0.021 mm\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 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 9055100072000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731648446770,"sku":"9055100072000","price":217.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_a2c3d93e-ea3e-40fe-8aef-e56477b1d7e7.jpg?v=1788733546","url":"https:\/\/voomisupply.com\/products\/guhring-9055100072000-screw-machine-drill-bit-0-2835-in","provider":"Voomi Supply","version":"1.0","type":"link"}
