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.

Please advise how we may be of assistance. Thanks Thom **Q: will this bit cut a 1/4" recess in a 3/4" red oak board? the recess has to be 3" x 4".** A: This is my bit of choice. This bit makes a good clean cut. So you are cutting a 3" x 4" 0.25" deep? **Q: does this bit cut acrylic like Plexiglas and leave a good edge?** A: This bit will cut acrylic, however a o-flute bit would be better suited. Any bit you use will probably still leave some visible signs of cutting, the edge can then be polished or some people use a torch to smooth the finish. The key is getting the correct chipload and making sure the part is held firmly. You are welcome to download my free CNC manual and chipload calculator from the technical section of our eoasaw website - the principles apply to any cutting situation. Please advise how I may be of further assistance. Thanks, Thom **Q: Would this bit be used to cut cirlces in plywood?** A: Whiteside carbide bit is very high quality. Good clean cuts in plywood. Yes I use this bit to cut circles. ## Frequently Bought Together - Whiteside RU2100 Spiral Upcut Straight Router Bit: 1/4 Inch Cutting Diameter, 1/4 Inch Shank, 1 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/7425170-whiteside-ru2100-spiral-upcut-straight-router-bit-1-4-inch](https://www.desertcart.tn/products/7425170-whiteside-ru2100-spiral-upcut-straight-router-bit-1-4-inch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-11*
