Built from M2 high speed steel with a bright uncoated finish, this bit holds a wire gauge size of 87, corresponding to a decimal diameter of 0.0098 inches (0.25 mm). The 118-degree standard point angle and web-thinned, tapered web configuration promote clean entry and reduced thrust in ferrous materials. With an overall length of 19 mm and a spiral flute length of 3 mm, this is a compact, purpose-built tool suited for HVAC, plumbing, and sheet-metal tradework requiring fine hole placement. Licensed machinists and tool-room technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for general-purpose use in cast iron and steel workpieces, consistent with its DIN 338 specification. The right-hand spiral flute promotes efficient chip evacuation during drilling. A straight-cylindrical shank with a diameter of 0.25 mm and shank length of 16 mm allows secure seating in standard keyless or keyed chucks. The 5xD flute-to-diameter ratio and regular spiral type make it a reliable choice for shallow-depth holes up to a maximum drilling depth of 0.104 inches (2.63 mm). It is sold individually but requires a minimum order quantity of 10 units per transaction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 87 diameter: 0.0098 inches (0.25 mm) for fine, precise hole placement\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction for durability in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent dimensional tolerances (h8)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length drill bit per DIN 338, Series 205, suitable for use in standard drill chucks accepting a 0.25 mm straight-cylindrical shank.

Secure the shank fully in the chuck before operation to prevent runout at this small diameter. Given the fine diameter, apply minimal feed pressure to avoid bit breakage. No coolant-through capability is present; use an appropriate cutting fluid externally when drilling ferrous materials at sustained depths.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 87\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 mm (0.0098 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.104 inches (2.63 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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: 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\u003eMaterial Grade\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9002050002500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749581455666,"sku":"9002050002500","price":76.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_7304b145-3046-41ee-b0da-e9bf6b8df6f2.jpg?v=1788907912","url":"https:\/\/voomisupply.com\/products\/guhring-9002050002500-jobber-drill-bit-wire-87-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
