Mitered Doors, Window Casings, Chair Rail And.....'Much More'

We know the name of these new router bits may sound silly but what would you have called them? All three of these router bits are perfect for making any number of custom woodworking projects. They are particularly suited to making mitered door frames for your kitchen cabinets or beautiful custom picture frames. While making the cut samples above, we found so many great uses for these tall profile bits that we didn't know exactly what to name them.

A note on quality: Like all of our Infinity Tools brand router bits, these three cutters have been made with only the most premium raw materials and machined to the most stringent standards in the industry. It takes this commitment to quality to produce intricate profiles on larger router bits like the ones above. Unlike inferior quality cutters, our router bits do not burn your material and their extra-sharp edges stay sharp longer. You'll notice our fanatical attention to quality and detail when you make flawless cuts in softwood, hardwood and man-made materials with these router bits.

A word of caution: Like all large or tall (or in this case, both) router bits, you need to run these cutters in your table mounted router only and reduce the speed to 12,000 RPM maximum.

Use these router bits for:

  • Mitered door frames
  • Custom picture frames
  • Chair rails
  • Baseboard
  • Window casing
  • Mirror frames
  • Crown moldings
  • Drawer fronts

If you struggle to get good results when using big router bits, our Top 5 Tips will definitely help.
If you struggle to get good results when using big router bits, our Top 5 Tips will definitely help.

If you're new to routing or simply new to using really big router bits, our "Top 5 Tips" blog can help. We've learned a few tricks over the years that will eliminate some of your trepidation and help you get smooth and safe results from the largest and heaviest router bits on the market. If you have experienced vibration or poor results when running big router bits, or just find them intimidating, stick around because our Top 5 Tips For Big Router Bits will definitely help.

It's important to remember that as router bits get bigger and taller they start to naturally remove more material per pass. As a result, it becomes more important to run them in a router table and not in a handheld router. Of course, there are exceptions like flattening a slab. But, the exceptions always require the use of sturdy jigs and sleds to stabilize the router. Always follow any safety instructions provided by the manufacturer of all equipment and tools and always remember to use good-ol' common sense.

A variable speed router like the Triton 3.25hp Plunge Router (116-270) is a must for using big router bits. If your router is not variable speed you can often use a router speed controller to get your router bits spinning at the correct speed.
A variable speed router like the Triton 3.25hp Plunge Router (116-270) is a must for using big router bits. If your router is not variable speed you can often use a router speed controller to get your router bits spinning at the correct speed.

Tip #1: A variable speed router is a must. Arguably the most important thing to remember when using big router bits is that they need to be run at a lower RPM than smaller router bits. The reason for this is due to their  "Tangential" speed which can be calculated as =  circum X rpm. As the router bit grows in diameter the carbide tip has to move faster to make a complete revolution at a given RPM. This means you need a variable speed router or a router speed controller so you can make sure all of your router bits are spinning at the proper speed.

All Infinity Tools router bits come packed in a storage pouch with a speed chart printed on the back so you always know what speed is best for the router bit you are using.

How will you know what the right RPM is for a specific router bit? The answer is to reference a router speed chart. All Infinity Tools router bits come packed in a pouch with a router speed chart printed on the back. This chart will get you in the ballpark and you can always tweak the speed up or down a little to suit the type of wood you are working with. Just don't be afraid to give those big bits some revs, running a router bit too slow can affect overall performance just as much as running it too fast.

Don't let you router bit bottom out. Collets pull the router bit down into the router slightly as they are tightened. If the router bit shank bottoms out, the collet will not be able to clamp properly.

Tip #2: Keep your router collet clean.
The collet is the most important part of your router. Its job is to hold the router bit securely and make sure it is perfectly centered and straight.  Over time the collet can collect sawdust and if any of that dust builds upon one of the clamping surfaces it can keep your router bit from seating properly when tightened down. As router bits get bigger a clean collet becomes more and more critical. If you take the time to maintain your router and keep the collet squeaky clean you will eliminate a major cause of vibration when running big and tall router bits. If your router has seen a lot of use you may also want to consider picking up a replacement. Believe it or not, collets, can and do, wear out. If you start noticing extra vibration when you run some big bits a new collet could get your router back to running like new.

Tip #3: Don't let the router bit shank bottom out.
While you need to make sure you have plenty of router bit shank inserted into the collet you never want the shank to bottom out. All router collets are cone-shaped wedges, called a taper. As you tighten the collet it applies equal clamping pressure on all sides of the router bit shank and pulls it down slightly into the router. If the shank has bottomed out it can't be drawn any deeper and the result is a bit that is not perfectly centered, or worse, not held securely. In either case, you won't be happy with the results you get when you hit the on button.

A space ball or rubber o-ring at the bottom of the collet stops the router bit shank from bottoming out and provides a little squish so the collet can clamp properly.

Mini Tip: Use a Space Ball or rubber O-ring as a spacer so your router bits can't bottom out. A space ball or rubber o-ring at the bottom of your collet will provide a little squish so your collet can clamp down properly on the router bit shank. It also allows you to be sure you have enough shank installed in the collet for a sure grip.  With a spacer at the bottom of the collet, you just drop the router bit in until you feel the squish and you are good to tighten and route.

Tools like stock guides, feather boards, coping sleds, and power feeders are a must when running large router bits. These router accessories make routing safer and more accurate so you get better results.

Tip #4: Never skimp on work holding.
When I say work holding I mean jigs, fixtures, feather boards, power feeders, and anything else that helps eliminate vibration and makes routing safer and more accurate. Jigs like the Infinity Tools Pro Coping Sled and Vertical Router Sled are ideal when you need to make cuts on the ends of boards. Feather boards like those made by Bow Products and Jessem Clear Cut Stock Guides are a must when edge routing. Sometimes a purpose-made jig is needed to get the best and safest results. And my personal favorite, the Infinity Tools Mini Power Feeder, is outstanding at creating consistent results, especially as workpieces get bigger. When it comes to big cuts, take your time and make sure you are set up properly before hitting the on button. I may not enjoy taking 5 minutes to set up my feather boards or special jigs, but it is always worth it when every cut turns out exactly as planned.

Taking multiple passes and removing smaller amounts of material is a must when using big router bits. Not only is this safer, but it will also help your router bits last longer and produce a much better final finish.

Tip #5: Take small bites.
This tip can apply to a lot of different woodworking situations. Making multiple passes to create a full profile or to reach a final depth will yield better results and eliminate the chances of tear-out and kickback that can destroy a workpiece or cause an injury. I like to use the same basic guidelines as I would when using a thickness planer. I make multiple passes leaving a light final finish pass. This allows me to remove the bulk of material quickly and the final pass gives me the smooth finish I need. When making long cuts this method will help identify touchy areas of a board with reversing grain that may require special attention, such as a slower feed rate to get the best results.
