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.

The 3 length definitely expands router capability. Maybe its just me, but the router carbide cutter on router bits seems to be getting shorter. As advertised.

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.

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!

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!

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.

This bit cuts clean. Like the double ball bearings.

Great bit for a reasonable price.

Works better than a regular flush trim bit.

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.
