Built from solid carbide with a bright, uncoated finish, this bit delivers clean cuts by directing chips downward, which reduces surface tearout on the top face of the workpiece. The cutter diameter is 0.125 inches with a 0.5-inch length of cut and a matching 1\/8-inch shank diameter. Overall length is 1.5 inches. The 21-degree helix angle and right-hand cutting direction are optimized for controlled material removal in production and fabrication environments. Installed by machinists and CNC routing technicians, this bit suits both manual router tables and CNC platforms.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for routing plastic substrates where surface finish quality on the top face is a priority. The downcut flute geometry suppresses fraying and chipping on soft or layered plastics, making it a practical choice for sign making, panel fabrication, and similar light-material routing tasks. Its compact 1\/8-inch shank fits standard collets on trim routers and CNC spindles commonly used in small-format and mid-format routing applications. It is not piloted and is used freehand or with a fence and guide system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDowncut flute geometry reduces tearout on the top surface of plastic workpieces\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides durability and edge retention over repeated passes\u003c\/li\u003e\n  \u003cli\u003eSingle-edge router style for controlled chip evacuation in plastic\u003c\/li\u003e\n  \u003cli\u003e21-degree helix angle optimized for smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to interfere with tight-tolerance cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, compatible with standard router spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in routers and CNC spindles accepting a 1\/8-inch collet.

Power down and de-energize the router or spindle before changing bits, and confirm the collet and nut are clean and undamaged before seating the shank. Insert the shank to the full recommended depth and torque the collet nut per the router or spindle manufacturer specifications. Inspect the bit for chipping or wear before each use and do not operate at feed rates or depths that exceed the tool manufacturer recommendations for carbide spiral bits in plastic.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: Bright\/Uncoated\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: Downcut\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\u003eMaterial Application\u003c\/strong\u003e: Plastic\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112821\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71177265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750966362418,"sku":"71177265","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39b025e5e8f84369e09d2585b40a8c90.jpg?v=1788920866","url":"https:\/\/voomisupply.com\/products\/accupro-71177265-downcut-spiral-router-bit-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
