Whiteside Router Bits RD2100 Standard Spiral Bit with Down Cut Solid Carbide 1/4-Inch Cutting Diameter and 1-Inch Cutting Length

Only use Whiteside bits in my machines. Excellent quality. You get what you pay for.

Made in USA by Whiteside. Enough said give it 6 stars in my book

I use this in my CNC for cutting wood. I was using a Niagara 1/4” endmill before. It was cutting okay but was starting to leave really stringy cuts in pine and birch plywood. Pretty sure it was getting dull, but still never cut as well as this one. It was also not cutting dimensionally accurate at all, and the cuts showed some lines (both of which I attributed to the CNC setup, not the bit). I’ve never been let down by Whiteside so I decided to order up a couple of these. MAN AM I GLAD I DID! The cut quality was SO MUCH better AND more accurate with this bit!! Just changing to this bit made my dimensions 100% accurate, and saved me SO. MUCH. SANDING. SO. SO. MUCH. Because I’m using this to make products to sell, this bit literally is saving me money on my finished products, by way of saving me many hours of sanding/finish work. I’ve had good luck and spoke highly of Whiteside before, but now I’m straight up a Whiteside evangelist! I’ve had great luck with Whiteside, Freud and Amana bits. Those cheaper bits can get the job done (like Ryobi), I’ve really found lately that the finished cuts coming off quality bits really is worth the extra couple bucks.

So far so good. Used it on my jasper jig to test some circle cuts. Its only a 1/4 inch bits. So dont try to beat it down. I only went 1/8th deep and finished with a flush trim. Works for what I need it to do

The best bits in my professional opinion! The spiral carbide bits ate razor sharp, cut clean and last long with demanding use. Cuts ply, pine, cedar, oak beautifully. My only choice of bits!

Cuts very clean

About 16 hrs of use dull not much better then China made bits

I am new to CNC carving, and purchased a few starter bits, this being one of them. I can tell the difference between the higher quality bits and the get what you pay for bits. This bit is very sharp and does a nice job. Very little tearing of the edges of the wood. The bit wasnt very much more expensive than the cheap ones, and has lived up to my expectations so far. Would recommend Whiteside bits right up there with Amana bits. I just ordered a 3 piece set of Whiteside ballnose bits for 3D(2.5D) carving, cant wait to try them as my get what you pay for bits are dull already.

worked for routing out an inlay. I did run into a little issue, but customer service was quick with a response and solution. Would buy from them again.

I used this with a shop-made fixture for cutting louver mortises on a historic shutter restoration. Perfect tool for the job. Whiteside makes good cutters.
