Solid Carbide Construction Outperforms Inferior Quality Competitors, Every Time!

Our compression router bits are impressive performers to start with. The solid carbide construction provides a long-lasting sharp cut, while the compression design of the flutes guarantees a clean cut on your top and bottom surfaces. By adding bearings both above and below the cutting flutes, you can work accurately with patterns mounted either above or below the workpiece.

We don't cut corners, so unlike inferior bits that are built with a steel shank, ours are true-solid, precision ground from one solid piece of C4 micrograin carbide. This insures perfect concentricity and a superior cut with extended tool life. We tested similar tools made on a steel shank and our true-solid construction ran circles around the competition.

Specs:

  • 85-940, Cutter Diam. 3/4" | Cutter Height 1-1/2" | Shank 1/2"
  • 85-941, Cutter Diam. 3/4" | Cutter Height 2-1/8" | Shank 1/2"

Dual Bearing Router Bits Offer These Benefits:

  • They can provide enhanced stability with the dual bearings riding on top and bottom templates. This extra support will reduce the chance of any wobbling or deviations.
  • Dual bearings are particularly beneficial for template routing giving the quick option of running with the template either above, or below the workpieces. This opens up the option for working in a router table, or freehand.
  • Top and bottom bearings allow for more versatility in creating edge profiles. They add greater flexibility in adjusting the depth and angle of cuts, leading to a broader range of design options.

These router bits are a step up from standard pattern bits. Solid carbide compression router bits leave a very clean edge in complicated grains, and the dual-bearing design allows for pattern work with the pattern mounted either above or below the work piece.

Infinity's compression router bits provide quality tear-out-free cuts at the top and bottom of the cut, and are perfect for template work in woods with complicated grains and plywood. These dual-bearing solid C4 micrograin carbide bits make that cut even better, and they'll stay sharp longer! By adding bearings both above and below the cutting flutes, you can work accurately with patterns mounted either above or below the workpiece. We offer both a 1/4" and 1/2"-shank router bit to best meet your application, as well as a money-saving two-router-bit set. 

The beauty of a dual-spiral compression router bit is the dual-flute design, with one facing up and the other facing down. These skewed cuts help support the wood fibers from both sides during the cutting process, preventing splintering and tear out.

The 85-940 is the beefiest of the two router bits. This ½” shank router bit has a ¾” diameter and a 1-½” cutter height. This router bit is able to easily cut plywood or solid wood (even cherry without burning). This is a solid router bit with great performance.

As mentioned, Cherry (prone to burning when cut) is no issue with the solid carbide compression router bits. Even when cutting across a void, the cut is clean and tearout free!

The 85-250 is the ¼” shank router bit. It has a ½” diameter cut with a 1” cutter height. It has All the features of the 85-940, but also includes the ability to follow patterns into tight corners because of it's smaller diameter.

This tricky corner was cut in two passes, both running from the outside into the corner to provide the best cut against the tricky grain. This was easily accomplished with the dual-bearing router bit by flipping the board over and raising the router  bit! That’s a clean cut into a tricky corner. Make sure your template work is flawless with our Solid Carbide Compression Router Bits.

Frequently Asked Questions

What is a double bearing pattern bit?

It is a router bit with bearings mounted both above and below the cutting flutes. This lets you template-rout with the pattern positioned either above or below the workpiece for maximum flexibility.

What shank size do these bits have?

These bits have a 1/2" shank and a 3/4" cutter diameter, suited to routers and router tables that accept a 1/2" collet.

What cutter heights are offered?

Two heights are available: 1-1/2" (item 85-940) and 2-1/8" (item 85-941). Both share the 3/4" cutter diameter and 1/2" shank.

Are these bits solid carbide or do they have a steel shank?

They are true-solid carbide, precision ground from one piece of C4 micrograin carbide rather than built on a steel shank. This ensures perfect concentricity and extended tool life.

Can I use these in a router table?

Yes. The dual bearings let you run the template above or below the workpiece, so you can work in a router table or freehand.

Why does the bit cut cleanly on both top and bottom?

The compression design of the flutes shears wood fibers toward the center of the cut, guaranteeing a clean edge on both the top and bottom surfaces of your workpiece.

What advantage do dual bearings give over a single bearing?

Dual bearings ride on top and bottom templates for enhanced stability, reducing wobble and deviations while adding flexibility to adjust cut depth and angle.

What projects are these bits good for?

They excel at template routing duplicate parts and creating edge profiles. Pair them with our router templates for repeatable, accurate results.

Who makes these router bits?

They are made by Infinity Cutting Tools, ground from a single piece of C4 micrograin carbide for superior concentricity. Browse more carbide router bits from Infinity.

What other bits pair well with these pattern bits?

Pair them with solid carbide spiral bits for plunge and grooving cuts, or explore flush-trim router bits for edge trimming.
