With a 0.25 inch cutter diameter and a 1.25 inch length of cut, it delivers efficient chip evacuation in a single-edge, right-hand cutting configuration. The upcut flute geometry pulls chips up and out of the cut, reducing heat buildup and improving cut quality in thermoplastics and engineered materials. At 3 inches overall length with a 1.75 inch shank, the bit fits standard 1\/4 inch collets on CNC routers and handheld routing equipment. A 21-degree helix angle balances aggressiveness with surface finish quality.\u003c\/p\u003e\n\u003cp\u003eThe 63-726 is suited for routing operations in fabrication shops, sign shops, and manufacturing environments working with sheet plastics and solid surface materials. Its single-edge design is optimized for materials that can melt or smear under excessive heat, making it a practical choice for acrylic and PVC cutting where clean edge quality matters. The uncoated solid carbide construction provides durability in non-ferrous and plastic applications without the added cost of specialty coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for durability in plastic and hard material routing\u003c\/li\u003e\n  \u003cli\u003eUpcut single-edge flute clears chips efficiently and reduces heat in thermoplastics\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle balances cut aggressiveness with surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and handheld routers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no coating to delaminate during abrasive material contact\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank fits common collet sizes across CNC and portable routing platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with acrylic, nylon, PVC, polycarbonate, and solid surface workpiece materials.

Before installing or changing bits, power down the router and confirm the spindle has come to a full stop. Seat the shank fully into the collet and torque to the router or collet manufacturer specification  -  do not rely on feel alone. Inspect the cutting edge for chips or damage before each use, as carbide is brittle and can fracture if the bit is dropped or mishandled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.25 inches\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: 1.75 inches\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: Single Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Acrylic, Nylon, PVC, Polycarbonate, Solid Surfaces)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 63-700\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: ONSRUD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63-726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67912834285874,"sku":"63-726","price":84.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a6d17e5ac957f5126d7b0f6c28f50d1_f88bf295-7bc8-4a48-ad31-f1aa3ffce2e7.jpg?v=1791240089","url":"https:\/\/voomisupply.com\/products\/onsrud-63-726-spiral-upcut-router-bit-0-25in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
