Its 1" cutting length and downcut spiral helix provide clean, tearout-free edges, making it ideal for grooves, dados, and inlays on hardwoods, laminates, and plywood. Engineered for stability and smooth chip ejection, it excels in both handheld and CNC routing applications. ## Description Spiral bits provide a shear cutting edge that leaves a smoother cut than standard router bits. The down cut spiral design provides the best top surface edges, ejecting chips away from the router when routing through material. This design also decreases the tendency to lift thin/small work pieces during CNC routing. ## Features - TOOL SPECS: Solid carbide, downcut spiral with 1/4" cutting diameter, 1/4" shank, 1" cutting length, and 2-1/2" overall length for use in routers with a 1/4" collet. - DOWN CUT SPIRAL: Down Cut Spirals ensure a clean edge on the side of the material closest to the router. Perfect for clean, top edges in handheld routing or CNC applications. - HELIX: Ideal for shallow grooves, dados, and inlays with a handheld router. The spiral helix offers a shearing action for clean, crisp cuts while outperforming standard straight bits. - CLEAN FINISH: The downward cutting action eliminates tearout when cutting grooves, dados, slots, and pockets in veneer, laminates, and plywood for precise woodworking results. - STABILITY: Great for holding thin sheets or small pieces in place during CNC routing operations, ensuring precision and stability. Ejects chips away from the router when cutting through material. - MATERIALS: Performs best with hardwoods, softwoods, plywood, MDF, laminates, veneers, and hard plastics for versatile woodworking applications. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000K29T64 | | Best Sellers Rank | #34,976 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #14 in Spiral Router Bits | | Brand Name | Whiteside Router Bits | | Customer Reviews | 4.8 4.8 out of 5 stars (689) | | Cut Type | Down-Cut | | Cutting Diameter | 0.25 inches | | Cutting Length | 1 inches | | Global Trade Identification Number | 00844278006070 | | Item Diameter | 0.25 inches | | Item Weight | 1.12 ounces | | Manufacturer | Whiteside | | Material Type | Carbide | | Model | RD2100 | | Number of Flutes | 2 | | Number of Items | 1 | | Part Number | RD2100 | | Size Name | 1/4 inches x 1 inches | | UPC | 733353264002 844278006070 | | Unit Count | 1 Count | ## Product Details - **Brand:** Whiteside Router Bits - **Cutting Length:** 1 inches - **Item Weight:** 1.12 ounces - **Material:** Carbide - **Size:** 1/4 inches x 1 inches ## Images ![RD2100 Standard Spiral Bit with Down Cut Solid Carbide 1/4-Inch Cutting Diameter and 1-Inch Cutting Length - Image 1](https://m.media-amazon.com/images/I/71EmFaDnPnL.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/7425171-rd2100-standard-spiral-bit-with-down-cut-solid-carbide-1](https://www.desertcart.kr/products/7425171-rd2100-standard-spiral-bit-with-down-cut-solid-carbide-1) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-29*
