These are really nice! Well worth the price!

I am a pro cnc operator and these bits are as good as any I have bought. Probably better.

This bit is probably the worst by Spetools. It does not cut accurately and is not sharp at all compared to other compression bits. I would not recommend.

Exceeded all expectations.

Leaves a nice finish and does as it should

I use my CNC machine about 50 hours or more a week. So far this bit alone has lasted a week. It's still cutting. I will end up buying allot. I like how they cut.

I like the bits from this company. They are sharp and long lasting for my Cnc projects.

The bit lasts longer then normal. The cut was clean from top to bottom. Still working on the speed, but overall, very happy.

Great cutter

Minimal tearout. Works great.

This bit performs exceptionally well on plywood, was totally amazed by it's smoothness of cut. Use their 1/4 DC bit as well, will definately continue using this brand.

This is the first time I have used a compression bit in my CNC but I am amazed at both the speed with which it cuts and the smoothness of the cut. I will make sure I also have one on hand!

Used this bit to cut a 1/2 inch deep trough in a very hard oak tree trunk cookie. Cut was clean and smooth using a hand held battery operated cut out router. Not really the tool to use for such a thing but the bit made it happen and made fast work of it...

I use this on my Genmitsu PROVer Xl 4030 with a Dewalt 610 pocket router as my spidle. It cuts awesome at 24,000 rpms. A nice clean cut. I'm very happy with it. This bit replaced a more expensive bit and works better. This bit is in Carveco's tool database. I rounded this clock with this bit.

I purchased this to cut a 3 ft circle out of plywood. Made two passes and no rip out. Very happy with results as it was for a school project for kids and didn’t want them to get splinters. Light sanding to softened edges.

Worked wonderfully on my CNC while making trays out of pine and cedar. Very clean cutting.

ehh.
dulled after 30 1/4" deep x 1/4" wide mortises done in two passes. then burned my material

While running a job, I accidentally thought it was another bit that was much more hardcore. So I was running it at speeds that I shouldn't have. I was so impressed with how it held up and performed.

Dull after one cut

I love these bits, I do feel that they burn out a little faster than I like, but I do put them through a lot when I use them.

Set one of these compression bits up in my machine to process some nested parts on .765" melamine. Cutting depth is .350" @ 400 ipm for two passes leaving just an onion skin for the last pass. After running one sheet, I noticed edge chips on the top side. Flip them over and it's just as bad. Switched back to an existing tool to finish the remaining 8 boards. Truly disappointed, but certainly not surprised.

Great quality for the price. Description is spot on.

I use these for cut out on my CNC and love the clean cuts and durability they produce. One bit will cut an average of 20+ sheets of particle board, MDF, Baltic birch plywood. Run at the proper feed and speed of course. Don't run this bit too slow or it will burn and dull quickly.

This bit is not sharp and burns its way through the cut straight out of the box

Excellent performance. Cuts just as well as my name brands costing twice as much. I'm very pleased with my purchase and I will definitely purchase SpeTool cnc bits again.

Great for cutting wood and seem to be very good quality. I will buy more

Très bonne qualité!

It comes with a nice packing and works great 👍

Guys and Gals...let me help you out.
Machine: Onefinity
Material: Baltic Birch
Material Thickness: 18mm or ≈3/4"
Plunge Rate: 50 in/minute
Plunge Depth: 20mm! (yes...i'm going 2mm past material thickness so cutting baltic birch as well as 2mm of MDF wasteboard.

Cut Feed Rate: 150 in/min (at full material depth of cut0)
Finish Pass Feed Rate: 250 in/min (full depth of cut - getting 220 grit sandpaper finish!!!!!)

Now that I've posted that.....SpeTool.....you should adopt me :) Seriously this is a great bit and I would highly recommend.

Broke in half on the first cut. China made BS

Absolutely perfect for cutting DIY T tracks. Along with a 1/2” T Router bit from AMZ, results were very satisfying once you learn to do the first or second cut with your compression bit. The final pass with your T router bit completes the process. Great when pair off with 1/4-20 bolts.
