Whiteside Machine Company has been in the router bit business for over 30 years providing customer with quality products while at the same time striving to achieve complete customer satisfaction. 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.

I had to laugh - I'll use this mostly in a handheld router, but used it in my router table this time. An upcut bit is a down cut bit when used in a router table. Of course, it made beautiful cuts (cutting slots for T-bolts in a jig I was making). Very happy.

Used a cheap bit to do a 5/16 deep 1/4 wide dado in maple. Bit snapped like a twig. Bought this to replace and chewed through it like hot knife through warm butter in a hot room. Whiteside from now on

I just want to mention that this bit is only 2-1/2” end to end, so if you’re intending to use it with a Porter-Cable style guide bushing in a mortise routing jig, you’re never going to get the full one-inch (1”) depth of cut. The collet will hit the retaining ring of the guide bushing at about 3/4 ” plunge depth. The P-C guide bushing is roughly 1/2” deep, the retaining ring is about 1/4”, the router base is 1/4” thick, and you need at least 1/2” inside the collet to safely use the bit. You get sparks from the metal-on-metal contact from the router collet hitting the retaining ring of the bushing before you get to a full one-inch plunge depth. This bit should have been at least half an inch longer (i.e. 3” long) to be usable in this configuration. The bit itself cuts fine if you’re using it some other way. Other manufacturers’ bits are 3” long and do not present a similar problem.

As a rule, I tend to buy Whiteside for bits that I think I'll use a lot, and Yonico for the more specialized stuff that I'll use infrequently. I have bits from other high-end bit manufacturers like Freud and Amana, and while great, they never seem to be quite as good as what I get from Whiteside.I had never used a solid carbide spiral bit like this before, but I was very impressed by the initial quality and sharpness (WEAR GLOVES!), and it's even better in use. It's so good for routing dadoes, that I find myself opting to make several passes with this bit, rather than use the larger diameter straight bits (also whiteside) that I've been very happy with.Great product, great value.
