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

Nice clean cuts. Not over priced. I love Whiteside bits. I use 1/4” and 1/8” down cut bits.

Works perfect shavings are forced down leaving a clean cut..

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

I needed a way to expand the 30 gas cooktop cutout on my Corian countertop to accommodate a new 36 cooktop replacement. After investigating online the various options for cutting Corian, it looked like using a router with a spiral bit was the best option. Since the countertop was already installed, the cutting needed to be done from the top down. A Down Cut bit seemed to be the best since it would minimize any chipping of the top Corian surface. I went with the Whiteside bit since it was highly rated. Im glad I did. I used a plunge router for the cutting since I thought it would be easier to control the cut. It was difficult to put a straight-edge template on the existing countertop because there was nothing to clamp it on to. I ended up free-lancing the cut and taking it slow to maintain the straight line. This bit is extremely sharp and the cutting went well. I took it in three passes to minimize the stress on the bit. The cutting created a lot of chips and dust from the Corian. Be sure to have a shop vac handy so you can see what youre cutting. After the cutting was completed, the bit is still sharp. Overall, Im pleased with the purchase. The only complication was at the back end of the cut by the back splash wall. There wasnt enough clearance for the router to reach all the way to the end. I had to finish the last 1-2 inches of the cut with multi-tool using a carbide blade. Im sure glad I didnt have to make the whole cut that way. It would have taken forever. The blade generates a lot of heat and melts the plastic.

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.

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

Fast shipping and worked great.

Ive cut through about 48 linear feet of 3/4 MDF (medium density fiberboard) and the bit is still almost as sharp as when it was brand new. MDF is notorious for dulling all types of saw blades and router bits. Im happy with how well the Whiteside bits are holding up. Ive used other brands of spiral bits that were dull after just a few uses in MDF.

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.

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