SpeTool Spiral Flush Trim Router Bit,1/4 Inch Shank 1-1/8 Inch Cutting Length Extra Long 3 Inch OVL,UP Down Compression Bit for Wood Trimming

Used this to make a speaker mount out of 1/2” acrylic. Highly recommended.

There may be some better ones out there, but for the price, I love it!

This bit cuts clean. Like the double ball bearings.

Although these bits I think were designed for a CNC application, I have had great success with them so far. Only time will tell as I use them more. Overall pleased with ourchase

Quality bit at a reasonable price. Leaves a great finish with no tear out. Highly recommend. You get what you pay for with router bits!

Its very durable, sharp and it edges great. I give it 5 stars

Ive used many different flush trimming bits of various sizes, but this one left the smoothest finish. Easy to use and long enough for guitar work. Highly recommended.

Im concerned about this breaking if its used to remove too much stock at once but its a decent bit for where a 1/2 bit wont go. Maybe they make 3/8 trimming bits as well which should be sturdier. I broke a 1/4 spiral bit once taking too deep a cut.

Worked well on the first few cuts into a pine board. Tried it on an oak board and the guide bearing flew apart and wrecked my project I was building. I wont be buying this again, not very well built.

Works exactly as expected with no tear out on top or bottom. The small diameter helps get into the tighter areas and the spiral cut means it’s much less likely to kick back than a straight bit
