With a 0.375-inch cutter diameter, a 1.625-inch length of cut, and a right-hand cutting direction, it evacuates chips efficiently by pulling them upward out of the cut. The 21-degree helix angle promotes smooth shearing action in dense thermoplastics and reduces heat buildup at the cutting edge. A 0.375-inch shank diameter fits standard router collets used in CNC routers and handheld routing applications. The uncoated carbide construction delivers consistent edge quality without a coating that can chip or peel under aggressive feed rates.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for routing acrylic, nylon, PVC, polycarbonate, and solid surface panel materials in both production shop and field service environments. The upcut geometry makes it a practical choice for through-cuts and profiling passes where chip clearing is a priority. It is part of the ONSRUD 63-700 series, which targets hard plastic and composite material applications common in fabrication, sign-making, and countertop work. The 3.5-inch overall length provides adequate clearance for fixturing on most CNC router tables.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for durability in hard plastic and composite materials\u003c\/li\u003e\n  \u003cli\u003eUpcut flute geometry evacuates chips away from the workpiece surface\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle promotes smooth, shear-cut action and reduces heat\u003c\/li\u003e\n  \u003cli\u003eSingle-edge design allows aggressive feed rates in suitable materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains sharp edge geometry without coating delamination risk\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and handheld router setups\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 materials.

Power down and de-energize the spindle completely before inserting or removing the bit. Seat the shank fully into the collet to the manufacturer-recommended depth and torque the collet nut with the appropriate collet wrench  -  do not use pliers or makeshift tools. Verify spindle speed and feed rate settings are appropriate for the workpiece material before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Upcut\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\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Acrylic, Nylon, PVC, Polycarbonate, Solid Surfaces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiloted\u003c\/strong\u003e: No\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: 0.16 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: 63-735\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67915093442866,"sku":"63-735","price":134.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1a9ef50256bae80c6dd223386f63b8d_2f909779-ff6c-4a13-b982-fdbeb1863af0.jpg?v=1791252216","url":"https:\/\/voomisupply.com\/products\/onsrud-63-735-upcut-spiral-router-bit-0-375-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
