With a 1\/4 inch diameter, a 90-degree point angle, and a titanium nitride (TiN) coating, this tool handles center drilling, chamfering, spotting, and peripheral milling without a tool change. The 4-flute geometry provides good chip evacuation and surface finish in a range of workpiece materials. Machinists and tool-and-die professionals rely on drill mills like this to reduce setup time and improve hole-to-feature accuracy on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis drill mill suits precision machining applications in job shops, mold-making operations, and production environments working with ferrous and non-ferrous metals, plastics, and composites. The 3\/4 inch length of cut allows engagement at moderate depths while the 1\/4 inch shank diameter is compatible with standard collet chucks and end mill holders. The 2-1\/2 inch overall length fits typical spindle clearances on vertical machining centers and knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree point angle enables accurate spotting, center drilling, and chamfering in a single operation\u003c\/li\u003e\n\u003cli\u003e4-flute design supports both drilling and side milling with improved rigidity over 2-flute versions\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides stiffness and wear resistance superior to HSS tooling\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends tool life in common machining materials\u003c\/li\u003e\n\u003cli\u003e1\/4 inch shank diameter fits standard ER collets and end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard selection for CNC machining centers, knee mills, and drill presses using 1\/4 inch collet chucks or end mill holders.

Secure the shank fully into the collet or holder to the recommended grip depth before tightening to prevent pullout under load. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Follow the machine tool manufacturer guidelines for runout tolerance and collet torque when setting up small-diameter carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15316-C1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51755077927218,"sku":"15316-C1","price":88.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca2c7b2feb44135aaea507d5216de145_50870ba6-30ad-43b5-9013-880dcf6c2826.jpg?v=1788950905","url":"https:\/\/voomisupply.com\/products\/harvey-tool-15316-c1-drill-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
