Spiral Flush-Trim Router Bits，Solid Carbide Flush Trim Router Bit 1/4-Inch Shank Spiral Flush Trim Up Cut from TACKPRO (1/4 Shank Up-Cut)

Cuts through wood like butter and is not that expensive.

I use it for routing 3/16 beadboard. Waaay better than the formica bit I was using.

Using this bit in a router table with adequate dust collection. The top cut is nice and clean, but the underside cut is ragged. Even with the dust collection, it throws a lot of these shredded wheat shavings around. Causing me to have to stop and vacuum after every cut. Not great for time management. More expensive bits do not do this. For the money, it is sharp, it does cut and it gets the job done, but it adds time when you have to sand edges and clean up the mess.

This was my first spiral flush trim bit and am very impressed. It seems to cut so much faster and cleaner that the 2 flute bits I have been using for MDF guitar templates. For the price, its a no brainer buy.

I was excited to use this router bit. Unfortunately it broke after cutting about 10” of wood. I was cutting out a pattern in soft 1/2” plywood and the bearings flew off. This damaged my template and the piece I was cutting. Not sure what holds the bearings on but I found them on floor on a pile of sawdust. Very glad they didn’t fly off and hit me.

Bearings came apart after just a few uses. Switched to a Diablo flush bit 3 flute and that’s been working strong weeks now. I bought three bits from you. All three the bearings came off.

Less than 10 seconds into my first cut with pine plywood and it snapped in half. Very poor product

Sharp long lasting bit. We use them for cutting window and door openings out when framing. Used with a trim router. I havent used in my big router yet.

Got the bit to route off the bullnose off stairs for hardwood install instead of cutting. The bit proved useless in that as it could not handle the 1 oak boards and just would not cut it. If you planning on making thick templates or routing hardwood look for something else.

Lasted about 30seconds cutting big box store birch.
