Built from high speed steel (HSS), it features a 0.25-inch cutter diameter, a 1-inch length of cut, and a 3-inch overall length with a 2-inch shank length. The upcut flute geometry pulls chips up and away from the cut, reducing heat buildup and helping clear material efficiently. A 19 to 32 degree helix angle supports smooth chip evacuation on softer and medium-density materials. The uncoated finish is standard for general-purpose routing work where coating is not required by the application.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in block and plate aluminum as well as natural wood. It suits CNC routing tables, handheld routers, and router spindles where a 1\/4-inch shank collet is available. The right-hand cutting direction is compatible with standard router spindle rotation. Typical users include CNC machine operators, woodworkers, fabricators, and production shops running aluminum plate or solid wood workpieces. The compact 0.25-inch diameter makes it well suited for narrow slots, detail passes, and profile cuts where a larger tool would not fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUpcut flute geometry evacuates chips away from the workpiece surface\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for aluminum and natural wood\u003c\/li\u003e\n\u003cli\u003e19 to 32 degree helix angle supports smooth cutting action\u003c\/li\u003e\n\u003cli\u003eDouble-edge design for balanced cutting load\u003c\/li\u003e\n\u003cli\u003eUncoated finish for general-purpose routing without added coating cost\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction matches standard router spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in routers and CNC spindles fitted with a 1\/4-inch collet.

Power down and lock out the router or spindle before inserting or removing the bit. Seat the shank fully into the collet to the recommended engagement depth and tighten the collet nut to the router or spindle manufacturer's specification. Verify spindle speed is appropriate for the material and cutter diameter before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Upcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Double Edge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 19 to 32 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Block and Plate Aluminum, Natural Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiloted\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: ONSRUD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40-111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67911214334258,"sku":"40-111","price":27.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1d43a54d6e45a3f5518064908618863.jpg?v=1791206708","url":"https:\/\/voomisupply.com\/products\/onsrud-40-111-upcut-spiral-router-bit-1-4-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
