Best Straight Plunge Router Bit Under $25 (2026)

Specs compared

Specifications are manufacturer rated, as published on each listing and collected 22 October 2026.

What the listings tell you

We read four straight plunge router bit listings. Two give full cutting dimensions, one gives a 4-piece size range, and one is thin on everything but size. Only one listing states an RPM figure, and none states a warranty term with a concrete length. Two listings contradict themselves between the title, bullets and spec table, so read each one closely: the parts list and the title deserve more trust than the spec table. The listings agree on the basics, two flutes and carbide edges, and differ on shank size, depth and how much they tell you.

Buying guide: how to choose the best straight plunge router bit under 25

Shank size: 1/4 in or 1/2 in

The shank must match your router’s collet. Two listings here use a 1/4 in shank, the Wolfride set and the FivePears, and two use a 1/2 in shank, the Freud 12-118 and the EASEWORK. A 1/2 in shank runs with less vibration in a full-size router, while 1/4 in shanks fit trim routers and compact CNC spindles. Check your collet before you order; an adapter is not a substitute for the right shank.

Cutting diameter and depth

The cutting diameter sets the groove width. Three listings state a 1/2 in cutting diameter, and the Wolfride set spans 1/4, 5/16, 3/8 and 1/2 in across its four bits. Cutting length sets how deep the bit reaches: the Freud lists 1-1/4 in, the FivePears lists 1 in, the EASEWORK lists 3 in, and the Wolfride set lists 13/16, 1, 1-3/16 and 1-3/16 in per bit. Match the diameter to your groove and the length to your stock thickness; the bit must reach full depth without the shank rubbing the workpiece.

Carbide and flutes

All four listings describe carbide cutting edges with two flutes. The Wolfride bullets name YG6 carbide with a 45# carbon steel body, the Freud names TiCo Hi-Density Carbide, the FivePears names carbide inserts, and the EASEWORK names tungsten carbide. Two flutes are the standard for straight bits: they clear chips well in wood and composites. The Freud listing adds precise shear and hook angles for a smoother cut, which is the kind of geometry detail worth paying attention to.

Plunge capability

A plunge bit must enter the work from above without walking. The Freud listing is the clearest here: it states that the end of bit relief allows for fast plunging. The EASEWORK listing describes smooth entry and clean finishes for plunge routing. The other two listings do not name plunge geometry, so treat their plunge ability as unstated. If your main job is plunging, the listings that name plunge features are the safer read.

RPM ratings

Only two listings state a speed figure. The FivePears listing gives RPM 18000, and the EASEWORK listing is rated for 22,000-24,000 RPM. The Wolfride and Freud listings state no RPM. Run the bit at the speed your router and the listing agree on; a small diameter bit at low speed burns, and an overspeed bit in a big router is unsafe. When the listing is silent, start slow and read the cut.

Set or single bit

One bit does one job; a set covers a shop. The Wolfride 4-piece set spans 1/4, 5/16, 3/8 and 1/2 in cutting diameters on 1/4 in shanks, which suits a maker who cuts many groove widths and does not want to buy four singles. The Freud, EASEWORK and FivePears listings each sell a single bit, which suits a maker who knows the exact diameter and depth the job needs. A set saves repeat orders; a single bit gives the exact geometry for one job. None of the listings states a storage case, so plan where the bits live: loose bits chip each other in a drawer.

Materials each bit lists

Stay inside the materials the listing names. The FivePears listing names wood, MDF, particleboard, plywood, compact panels and acrylic, and warns not to cut metal. The Freud listing names composite materials, plywoods, hardwoods and softwoods. The EASEWORK listing names wood, plywood, MDF, particle board and plastics. The Wolfride listing names CNC, table mounted and handheld routers without a material list. Never cut metal with these bits, and never cut PVC or vinyl on a laser or a router without checking the material guidance first.

Project Match

• Sign lettering and grooves in wood: the Freud 12-118, with stated shear and hook angles for a smooth finish, or the FivePears with its 1/2 in cutting diameter.
• Dadoes and deep cuts: the EASEWORK, with a 3 in cutting depth, the longest stated here.
• Trying several groove widths: the Wolfride 4-piece set, spanning 1/4, 5/16, 3/8 and 1/2 in diameters.
• CNC work: all four listings state use on CNC routers; the Freud and EASEWORK list 1/2 in shanks for full-size spindles.

How the scores add up

Each bit is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. For router bits, performance follows the stated cutting geometry and carbide, build follows materials and stated construction, and value weighs what the listing gives against the class. No listing here states a safety certification or a concrete warranty term, so safety and warranty score zero across the board.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

FAQ: lasers and CNC

What is a straight plunge router bit?

A straight bit that can enter the workpiece from above to mill a flat-bottomed groove or dado. The Freud listing states that its end of bit relief allows for fast plunging, and the EASEWORK listing describes smooth entry for plunge routing.

What shank size do I need?

The shank must match your router’s collet. The Wolfride set and the FivePears use a 1/4 in shank; the Freud 12-118 and the EASEWORK use a 1/2 in shank. A 1/2 in shank runs steadier in a full-size router.

Can these bits cut metal?

No. The FivePears listing warns not to cut metal, and the other listings name wood, composites, plywood, MDF and plastics only. Use bits rated for metal if that is your material.

How do I choose a cutting diameter?

Match the diameter to the groove you want. Three listings here state a 1/2 in cutting diameter, and the Wolfride set offers 1/4, 5/16, 3/8 and 1/2 in across four bits, which suits a shop that cuts many groove widths.

Do I need a special router for these bits?

All four listings state use on CNC routers as well as handheld or table-mounted routers. Check that your router’s collet matches the bit’s shank, 1/4 in or 1/2 in, and that your spindle can hold the bit at the listed RPM where the listing states one. A trim router with a 1/4 in collet takes the Wolfride set and the FivePears; a full-size router with a 1/2 in collet takes the Freud and the EASEWORK.

What does anti-kickback mean on a router bit?

The FivePears listing states an anti-kickback design, which the listing presents as giving higher stability and less vibration. The other three listings state no anti-kickback feature. Treat it as the maker’s claim, and keep the workpiece clamped and your hands clear whatever bit you run.
