Straight Router Bits do the Work

Certainly the “bread and butter” of woodworking bits, straight router bits are available in a wide variety of sizes. Their C4 carbide-tipped cutters promise smooth long-lasting cuts, yet they’re relatively inexpensive compared to spiral bits. Available in standard, pattern routing, and flush trimming varieties … these workhorse router bits from Infinity have you covered. 

Flush Trimming Router Bit

Flush Trimming Router Bits

With a ball bearing mounted at the tip, flush trimming router bits are the perfect choice for cleaning up laminated posts, or almost any flush-trim application.  Even though a flush trim router bit is considered a “straight router bit”, Infinity router bit designs utilize a downshear angle for optimal cut quality.

Bearing Matches Cutter Diameter

The shear angle of the carbide produces wispy shavings and clean flush trimming cuts – even in chip-out prone hardwoods like white oak.  Since the bearing matches the carbide cutter diameter, you’re guaranteed a flush cut. 

Flush trim bits are available with top or bottom bearings, depending on use.

Pattern Routing Bit

Every furniture maker or guitar builder has a prized collection of pattern routing bits.  Like flush trimming router bits, the bearing matches the cutter diameter.  However, the bearing is located on the collet side for a wide range of cuts, including both handheld and router table operations.  Shown is Infinity model #12-771B with ½” shank and ¾” cutter dia. x 2” cutting length.

Cut Close, then Pattern Rout

Use your template to mark a pencil line, and remove most of the waste with a jigsaw or bandsaw.  With the template firmly clamped in place, remove the remaining waste with a pattern routing bit.  Move the router in a counterclockwise direction for the most predictable results.

The Basic straight router bit.

Mr. Basic

Is a straight router bit the plain one?  Maybe, but what woodworking shop could function without a selection of straight router bits?  Great for cutting dados and rabbets, straight router bits will have your case goods and cabinets coming together flawlessly.

Great for making grooves.

Carcase Dados are a Snap

Chuck a straight router bit in your handheld router, and follow a straightedge to plow perfect dados!  Mr. Basic might do the simple things, but he does them well.  Crisp, clean dados are virtually splinter-free in this wide hardwood panel.

Perfectly sized grooves!

Precise Joinery

Quality carbide tipped straight router bits leave nothing to be desired.  Make sure to outfit your shop with a good variety of these value-conscious router bits.  The payoff is snug fitting joinery for all your woodworking projects. 

From thin enough for small inlays, to large material-hogging options, straight bits are available for many applications.

Wide Variety of Sizes

Straight router bits are available down to an incredibly small 1/16” diameter for fine precision work.  You’re sure to find the bit for your exact application.

Takes much of the sanding out of pattern work.

You’ll Never “Sand to the Line” Again

If you only had one part to make, there might be a case for sanding to the line.  However most projects need multiple parts, and benefit from a template and pattern routing bit.  Get unmatched speed and efficiency by pattern routing your parts!

Frequently Asked Questions

What router does an 8mm shank bit fit?

It fits any router that accepts an 8mm collet, a size common on many European and premium routers. Make sure you have the correct collet before use. Browse more straight router bits.

What are the dimensions of this bit?

It has an 8mm shank, a 5/16" cutter diameter, a 1" cutter height and a 2-3/4" overall length, with a straight cutting profile.

What can I use a straight router bit for?

Straight bits are ideal for dadoes, rabbets, pattern cuts and any job requiring a straight edge, which is why they are among the most-used bits in the shop.

What is the bit made of?

It uses micrograin carbide tips on a CNC-machined Fatigue-Proof steel body, a combination chosen for durability and accuracy. See more carbide router bits.

Why does Infinity use Fatigue-Proof steel for the body?

The special Fatigue-Proof steel body resists the stresses of routing for a stronger, longer-lasting bit, helping you get the most out of your investment.

Can this bit cut dados and rabbets?

Yes. With its 5/16" cutting diameter and 1" cutter height, it is well suited to dados, rabbets and grooves. For more grooving options, see our grooving bits.

Is an 8mm shank stronger than a 1/4" shank?

An 8mm shank is slightly larger than 1/4", giving a bit more rigidity and chuck contact, which can mean steadier cuts in routers that accept the 8mm collet.

What cutter diameter does this bit have?

This bit has a 5/16" cutter diameter with a 1" cutter height, making it handy for narrower grooves and edge work.

Can I use it for pattern routing?

Yes. Straight bits work well for pattern cuts and template work when paired with a guide. Explore the full straight router bit range for the right size.

Who makes these straight router bits?

They are made by Infinity Tools, using premium micrograin carbide and Fatigue-Proof steel to deliver high performance at a strong value.
