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

The bearing or bit was out of round rite out of the box with the bearing not able to spin freely without resistance. The bearing overheated and locked up after less than a minute of use. Would not recommend using your bit if it arrives in the same condition.

This bit cuts clean. Like the double ball bearings.

It is a 1/4 shank router bit. These smaller bits are for small finishing cuts and are fine for that purpose. I cannot attest to the longevity of this particular bit. I have had brand name bits go dull extremely fast and have had off-branded tools hold up admirably long. Time will tell, but for now, this bit seems to be holding its own.

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.

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

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

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

Bought to trim out patterns on a current project, and worked fine for like 30 min it kept sliding on its own while in the collet, and the bit decided to snap while router was on. The material that I was using was only pine, so it shouldn’t have had any problems. I’m just glad that I was not struck when it went airborne!

Work great for the price. Expect to replace them after using on mdf. 1 4x8 sheet worth of cutting and is pretty spent. For the price you can afford to toss them after use.

Great bit for a reasonable price.
