With a 1\/4-inch cutting diameter and a 4-inch overall length, this single-ended drill establishes precise center points without walking, reducing runout on subsequent drilling operations. The bright, uncoated finish is suitable for general-purpose work in steel, aluminum, cast iron, and similar workpiece materials. Machinists and tool-and-die professionals use spotting drills in manual mills, CNC machining centers, and drill presses wherever hole location accuracy is critical.\u003c\/p\u003e\u003cp\u003eThe 6000101 belongs to the PRECISION TWIST DRILL SPR-90 series, which covers 90-degree point angle spotting drills in a range of diameters. The 90-degree included angle matches the geometry of most standard jobber-length twist drills, allowing clean transition from the spot to the through-hole without an oversized chamfer. Typical applications include production machining, toolroom work, and prototype fabrication where tight positional tolerances are required. The straight cylindrical shank seats directly in standard collets, end-mill holders, or drill chucks without requiring special tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree drill point angle matches standard twist-drill geometry for accurate hole starting\u003c\/li\u003e\n\u003cli\u003e1\/4-inch cutting diameter with 0.2500-inch decimal equivalent for precise tool selection\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides good wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows easy visual inspection of cutting edges and is compatible with most cutting fluids\u003c\/li\u003e\n\u003cli\u003eSpiral flute, two-flute design promotes chip clearance during spotting operations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill for use in manual mills, CNC machining centers, and drill presses accepting a 1\/4-inch straight shank.

Secure the shank in a collet, drill chuck, or end-mill holder with adequate clamping length before running the spindle. Power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material and inspect cutting edges for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single Ended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPR-90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6000101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693468811570,"sku":"6000101","price":343.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d56c6520fb9c3b265dfced116075d5c.jpg?v=1788312839","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000101-spotting-drill-1-4-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
