Several woodworking magazines have tested Whiteside versus the competition and selected Whiteside as the winner for best router bits available in the market. Whiteside Machine Company was founded in 1970 as a general purpose machine shop in the basement of Bill & Bobbie Whiteside's home. Located in Western North Carolina near the furniture manufacturing town of Hickory, the company was often involved in making repairs or special parts for the furniture and woodworking field. A strong commitment to customer problem-solving, a can-do attitude, and innovative ideas, along with a growing core of dedicated employees, helped the business evolve into a manufacturer of woodworking equipment and tooling. Primarily through repeat business and referrals, the tooling business continued to grow to meet a demand for quality production router bits as well as custom application tooling. Today, Whiteside Machine occupies a 40,000 sq. ft. manufacturing facility and produces a complete line of solid carbide and carbide tipped router bits. Whiteside's quality, innovation, and customer commitment is still present in our superb product line, in the design of custom tooling to fill special customer requirements, and in the development of special machinery and tooling for our own manufacturing use. As always, Whiteside Machine is continuously striving to improve our product through new technology, improved production techniques, and ongoing research and development efforts; along with rigid quality control, vital customer feedback and extensive field testing. Whiteside Machine Company. Review: I like this bit like my other Whiteside bits - I like this bit like my other Whiteside bits. Woodworking is only my hobby so I can't attest to the longevity/durability of the bit. I have used this bit with a small trim router mounted on a table. I've checked the resulting cuts with my calipers and the bit cuts accurately and cleanly. The spiraling left clean surface edges and pushed the chips into the dado as I expected. I mostly made incremental passes at 1/8" depth but the few that I did at 1/4" depth looking just as clean but needed to go a little slower. I did notice that this bit was a tad bit harder to get into the collet of my router. When I checked the shaft, it appeared to be about .001 larger than the ones I compared it to. This seems to be within acceptable tolerance to me so I chocked it up to being new. Review: Great quality - Worked great for a walnut inlay project i recently built. ## Features - TOOL SPECS: Solid carbide, downcut spiral with 1/8" cutting diameter, 1/4" shank, 1/2" cutting length, and 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000K2FI8M | | Best Sellers Rank | #125,542 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #71 in Spiral Router Bits | | Brand | Whiteside Router Bits | | Brand Name | Whiteside Router Bits | | Customer Reviews | 4.8 out of 5 stars 658 Reviews | | Cut Type | Carbide-Tipped Cut | | Cutting Diameter | 0.13 inches | | Cutting Length | 0.5 inches | | Global Trade Identification Number | 00844278006018 | | Item Diameter | 0.13 inches | | Item Weight | 0.27 g | | Manufacturer | Whiteside | | Material | Carbide | | Material Type | Carbide | | Model | RD1600 | | Number of Flutes | 2 | | Number of Items | 1 | | Part Number | RD1600 | | Size | 1/8 inch diameter, 1/2 inch length | | Size Name | 1/8 inch diameter, 1/2 inch length | | UPC | 732454423509 785533344745 844278006018 733353600152 | | Unit Count | 1 Count | ## Product Details - **Brand:** Whiteside Router Bits - **Cutting Length:** 0.5 inches - **Item Weight:** 0.27 g - **Material:** Carbide - **Size:** 1/8 inch diameter, 1/2 inch length ## Images ![Whiteside RD1600 Spiral Downcut Straight Router Bit: 1/8 Inch Cutting Diameter, 1/4 Inch Shank, 1/2 Inch Cutting Length - Image 1](https://m.media-amazon.com/images/I/6198f1R0DfL.jpg) ![Whiteside RD1600 Spiral Downcut Straight Router Bit: 1/8 Inch Cutting Diameter, 1/4 Inch Shank, 1/2 Inch Cutting Length - Image 2](https://m.media-amazon.com/images/I/61-ESm-K2fL.jpg) ![Whiteside RD1600 Spiral Downcut Straight Router Bit: 1/8 Inch Cutting Diameter, 1/4 Inch Shank, 1/2 Inch Cutting Length - Image 3](https://m.media-amazon.com/images/I/51gtiqBAJPL.jpg) ![Whiteside RD1600 Spiral Downcut Straight Router Bit: 1/8 Inch Cutting Diameter, 1/4 Inch Shank, 1/2 Inch Cutting Length - Image 4](https://m.media-amazon.com/images/I/21F7w9xhFtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ I like this bit like my other Whiteside bits *by A***S on December 28, 2016* I like this bit like my other Whiteside bits.

I read several reviews where people using other brands of bits had them break easily. This bit cut into walnut and birch with no problem. I think Whiteside bits are some of the best router bits you can buy. ## Frequently Bought Together - Whiteside RD1600 Spiral Downcut Straight Router Bit: 1/8 Inch Cutting Diameter, 1/4 Inch Shank, 1/2 Inch Cutting Length - Whiteside Router Bits RD2100 Standard Spiral Bit with Down Cut Solid Carbide 1/4-Inch Cutting Diameter and 1-Inch Cutting Length - Whiteside Router Bits RU1600 Standard Spiral Bit with Up Cut Solid Carbide 1/8-Inch Cutting Diameter and 1/2-Inch Cutting Length --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/13765378-whiteside-rd1600-spiral-downcut-straight-router-bit-1-8-inch](https://www.desertcart.tn/products/13765378-whiteside-rd1600-spiral-downcut-straight-router-bit-1-8-inch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-08*
