NEED TO KNOW

Choose the Right Flush Trim Bit

Up-cut bits are shearing upwards toward the router and are the best general purpose choice for flush trim bits. On a router table, up-cuts help pull the workpiece down towards the table, helping the cut be more stable. 2. Down-Cut bits shear down and away from the router and are suited for trimming laminates or plywood when you absolutely need to have a crisp upper edge. Keep in mind that on a router table, down-cut bits can push the workpiece up and away from the router, potentially resulting in erratic behavior. 3.Compression bits are essentially a hybrid; the tip is up-cut and the rest of the flutes are down-cut essentially shearing the fibers towards the middle of the workpiece.

DO NOT Trying to Remove Too Much Material in One Go

It can lead to tear-out, burn marks, or rough edges. Instead: Try to rough-cut away as much extra wood as possible with a jigsaw or other method. Take multiple light passes(1-2mm per pass) instead of one deep cut. Adjust your router speed: spiral bits are designed to cut efficiently at 16,000RPM (about mid-dial on most routers). This serves two purposes: it helps keep heat build up at a minimum, prolonging the life on the edge and it keeps the lubricant in the bearings from overheating, degrading and ruining the bearing (especially on 1/4” bearings).

Pay Attention to Feed Direction

Moving your material in the right direction is super important for a clean cut and safety. Always try to cut with the grain to avoid tear-out. Conventional cutting is easier to control, while climb cutting can give you a smoother cut but takes more experience. Avoid starting a cut in end grain which can cause a kickback immediately (especially an inside cut in a charcuterie board handle). If you’re new to climb cutting, practice on some scrap wood first, and keep a firm grip on your router.

Keep Your Bits Sharp and Clean

Dull or dirty bits can lead to messy cuts and extra wear on your router. Clean off resin and dust buildup with bit cleaner or a simple household degreaser. Store your bits properly in a case or rack to keep them from getting damaged. Keeping your bits in good shape will make your cuts cleaner and help your tools last longer!

The angular cut up and down seems to cut cleaner. I use on a minimum 2hp router which seems to work best. Good Quality and clean cut.

My compression bit cut clean but the collar and bearing failed. I contacted SpeTool via email since I was outside of the Amazon return window and after confirming my details they replaced it within a week. Very happy with the replacement and both bits cut beautifully.

Not too bad but not the greatest bit Iâ€™ve used.

If you purchased this bit I would stop using it immediately. I spent last night in the ER due to this bit bending on me after using it the first time. I will not include photos of my injury but I was lucky enough to keep my finger.I did include the piece I was working on. I was removing a small bit of wood left over in the last hole. It was not more than 1/8â€ by 1/8â€ that the drill bit left over. Nothing that should have come even close to taxing the bit. This is where it grabbed the piece and threw it tearing out the bottom of the walnut.In the pictures you can see the slight bend in the stem. It was almost fully inserted into the collet and it still bent. When I got back home today I turned the router on to try and figure out how this happened and I found the bit wobbling around. My first thought was I didnâ€™t tighten it down enough so after checking that and making sure it was completely tightened I pulled the bit out and rolled it on my table. Itâ€™s very easy to see the wobble in it then.I am incredibly fortunate to still have my finger. I would not recommend this bit to anyone. Please be safe out there everyone!

Smooth cut even on end grain. Large diameter helps the bit not digging in the wood and getting trap causing tearout.Compares to a bit from bits and bits for less then half the price.

I love this router bit. I did some research on different cutting styles & chose this compression bit for clean cuts on both the top edge & bottom surfaces, & it does the job perfectly. I will be buying other bits from this brand when needed

Great addition although went for a top & bottom bearing which gets more usage

This router bit is awful, I bought it for flush trimming fretboards and it doesn't cut, it only tears up the bottom of the workpiece. I would return it but sadly amazon doesn't let you return anything after 30 days
