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

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

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.

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.

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

White sides has always been my tool of choice when it comes to quality router bits. These are top of the line quality I need for my furniture making business.

I just broke 3 bit on the same job I always run. I switched to another brand that my buddy uses and it finished the job perfectly. Whiteside quality isnt what it used to be. Ill never buy them again.

I needed to modify the holes for the balusters in a composite stair rail to adapt them to the slope of our stairs. The rails are expensive and I had 80 holes to modify, so I bought a trim router with an angle base and used this bit. That material is very hard on carbide saw blades, so I ordered two of these. The downward spiral left the exposed surface clean as a whistle and there were no indications it was getting dull after all 80 holes were cut back. Still have another stair railing to install, so theres another 80 holes in its future.

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

Fast shipping and worked great.

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.
