SpeToolSpiral Upcut Router Bit 1/4 inch Shank 1/4 inch Cutting Diameter Solid Carbide End Mill CNC Rourer Bits for Woodworking Wood Carving Tool

The media could not be loaded.  A spiral bit was recommended by a YouTube project video to cut a dado in the sides of a box to make a lid. I considered an expensive one, but thought that this might do. I can see now that I probably could have used one of my straight bits and gotten similar results. There's nothing wrong with this bit, it cuts through the soft popular that I'm using with no problem. Because it is an up-cut bit and I'm cutting a dado, the edge tends to be rough. I would have used a down-cut spiral, but didn't want the wood to "walk" on me due to the tendency to "lift." I found that I could get a smoother cut with this up-cut bit by simply slowing down my feed rate (not the rpm). The bit is sharp enough that I didn't experience burning. The quality of the bit seems excellent for the price, I've only just begun using it so I can't speak to durability. But the edges are polished and sharp. The bit spins true and the top part of the cutter produces a nice flat surface at the bottom of a dado. And, yes, as my video shows, it is Carbide.

This end mill arrived well packaged and on time. They come packed in a holder that is going to be useful for storage.These end mills are sharp and cut through rock hard maple with little trouble and a nice clean cut. I used them for slots and grooves and got good, clean edges.Recommended!

I wanted a router bit that i could use as a scroll saw. I have only used the 1/8 inch bit so far and i am convinced that my scroll saw will not be needed again. My first job was cutting a Bigfoot silhouette out if an old, dried out piece of 1/4 inch plywood. It took about a fifth of the time to do the job as it would have with a scroll saw or saber saw, and the cut was clean with little chipping. Awesome tool!

These Spetool 1/4" bits are great value for the money. Super sharp and they last quite a while. I'm very happy with them, and they've become my go-to bit for general work.

So far so good. No heavy cutting yet, only through 1/2" ply but it cuts smooth enough and plenty sharp.

Bought this to make box joints with my router table. Works great. Would buy again

Works great on my CNC I've cut hardwood, softwood and plywood with no issues

These bids are all in excellent quality for the money. Long life nice sharp bit, perfectly accurate for CNC routing of wood or other soft materials.

I watched a video comparing spiral v straight cut router bits and the evidence was compelling. With a straight cut router bit you get two rotating blades that hit the workpiece over and over again to remove waste The exit wound is usually ragged as the material chips out. With a spiral cutter it works much the same was a drill bit taking a constant cut along its length and avoiding chip out or at lease minimizing it. I strongly recommend this. I decided to buy this one which is a relatively cheap cutter for my first attempt and the results were excellent so I'm not sure I would spend more than this given they do a great job.

I've just tried it and I am very pleased with this bit. I'm intermediate / hobby carpenter. I'm just making some bow ties for my wife solid oak desk - previously I was using a straight 5mm bit - it worked, but its better off staying with shelf holes. This new bit chewed through the oak with a basic Bosch router without any issue at all - it was a real pleasure using this. It plunged straight down to 1cm without any complaints. Very sharp, smooth cut - couldn't ask for more

I use this cutter to carve out numbers and letters in wood with a hand held router. This cutter suits my requirements well and it will pass the test of time and frequent use I'm sure.

Only used the extra long 1/2” bit so far and was impressed with the results. Good quality and very sharp. Will have to take lighter passes with the 1/4” shank as too bigger cut you snap the bit.

Works very well. Spiral cut for me from here on in.
