Use these premium quality Plunge Point Straight router bits for dadoes, rabbets, pattern cuts or virtually any application requiring a straight edge. With these special straight router bits you can start your cut in the middle of the workpiece with ease and precision. They cut a smooth entry point and leave a flat bottom. All Infinity Tools Straight Router bits with plunge point feature a downshear cutting geometry for ultra smooth cuts.

These quality Top Bearing Pattern router bits feature a bearing above the cutter which mounts to the shank. When used in a table mounter router, this configuration allows you to place your pattern below your workpiece which means you can see what you're routing! For best results and longer router bit life we suggest you rough cut your work piece so it's about 1/8" larger than your pattern and then use your top bearing router bit to make the final cut.

All the router bits on this page feature a 3/4" cutter diameter with matching bearing O.D.

Frequently Asked Questions

What does the plunge point do?

The plunge point lets you lower the bit straight down into the middle of a workpiece to begin interior cuts, leaving a smooth entry point and a flat bottom. It is ideal for dadoes, rabbets, mortises, and inlays.

What is downshear cutting geometry?

Downshear geometry angles the cutting edges so they shear the wood fibers downward, producing an ultra-smooth cut and a clean surface. All Infinity plunge-point straight bits feature this design.

Will this 1/2" shank bit fit my router?

Yes, as long as your router accepts a 1/2" collet. The 1/2" shank gives the stability needed for plunge cuts and pattern work. See more straight router bits.

What is the cutter diameter of this bit?

All bits on this page have a 3/4" cutter diameter with a matching 3/4" bearing outside diameter, available in 1-1/2" and 2" cutter heights.

Why does the bearing match the cutter diameter?

Because the bearing's outside diameter matches the 3/4" cutter, the bit trims your workpiece exactly flush to the template for an accurate pattern copy.

How do I use the top bearing for template routing?

In a table-mounted router, place your pattern below the workpiece so the bearing rides on it while you see the cut. For best results rough-cut about 1/8" oversize, then make the final pass against the template. Explore our router templates.

What projects is this bit good for?

Dadoes, rabbets, mortises, inlays, stopped grooves, and pattern cuts where you need to start in the middle of a workpiece. Browse complementary grooving bits.

Can this bit cut a flat-bottomed groove?

Yes. The plunge-point straight bit leaves a flat bottom and a smooth entry point, making it ideal for clean dadoes and rabbets.

How do I extend the life of this bit?

Take light final passes with the bearing following your template rather than hogging out material in one pass. Removing less on the final pass reduces burning and helps the carbide edge last longer.

Who makes this plunge-point router bit?

It is made by Infinity Cutting Tools. Explore the rest of their carbide router bits for more straight, pattern, and grooving profiles.
