Built for Clean Edges, Pass After Pass

Four details that separate a usable set from one that ends up in the scrap drawer.

YG8 Micro-Grain Carbide

Diamond-ground YG8 tungsten-carbide edges rated HRA 89.5+ stay sharp through glue lines in birch plywood and slice oak and maple without scorching.

Sealed Pilot Bearings

Shielded steel bearings keep fine dust out and spin smoothly at high RPM, so they won't lock up and burn a groove into your finished edge.

True 6.35 mm Bare Shanks

Precision-ground steel with no paint, plus a laser-etched minimum insertion line, so the bit seats fully and stays put in your collet.

Labeled Indexed Case

A printed profile drawing and size under every slot, with tilting rows that let you grab the shank instead of the carbide.

How the EdgePro 15 Gets a Sand-Free Edge

Carbide That Slices, Not Scrapes

Carbide That Slices, Not Scrapes

The YG8 cutter takes a thin, clean shaving while the PTFE-coated body sheds pitch and heat, so the edge comes out pale and smooth instead of brown and fuzzy.

A Bearing That Keeps Rolling

A Bearing That Keeps Rolling

The sealed pilot bearing rides your workpiece or template evenly, with no friction drag and no step gouged into the face.

A Shank That Seats True

A Shank That Seats True

The bare 6.35 mm shank slides into the collet to the etched line and locks down without wobble, runout or creep.

Description

The Problem With Cheap Sets: Budget sets often use soft carbide, paint over the shanks and fit unshielded bearings. The result is burned edges, bits that slip in the collet and bearings that seize halfway down a finished board.

What's Different Here: The EdgePro 15 pairs YG8 micro-grain carbide with heat-treated alloy bodies, a PTFE anti-resin coating, sealed pilot bearings and bare 6.35 mm shanks, all balanced for 24,000 RPM.

Who It's For: Home woodworkers, DIY renovators and trim carpenters using a 1/4-inch palm, trim or plunge router. For heavy production cuts in one pass, a 1/2-inch shank set is the better tool.

Shipping & 30-Day Returns

Free Shipping: Every order ships free with full tracking within 24 hours.

30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.

2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.

Why Choose the Cosari EdgePro 15?

Cosari EdgePro 15 Detail

Balanced to 24,000 RPM

Anti-kickback body geometry keeps the cut controlled and quiet, with less vibration through the router and your hands.

PTFE Heat Shield

The crimson non-stick coating resists pitch buildup and friction heat, two of the main causes of black burn marks.

Crisp Profiles, Every Time

Sharp, accurately ground edges give you clean 90° corners and smooth radii that need little or no sanding.

Glass-smooth edges on hard maple and red oak right off the bit

Cut 40 feet of 3/8 roundover and 45-degree chamfer on hard maple and red oak this weekend with my DeWalt DWP611. Left a glass-smooth finish right off the bit—didn't even need to touch it with 120-grit sandpaper. The shanks are bare, precision-ground steel instead of being covered in thick paint that gums up your collet and throws off the runout at 20,000 RPM.

Two individual bits at the big box store cost more than this whole 15-piece set

Buying two single Freud bits at the big box store cost me $52 last month. Getting all 15 YG8 carbide profiles in a labeled index case for $35 with the 50% off deal is a complete no-brainer for a home shop. Every shank has the laser-etched minimum insertion line marked right on the steel so you don't have to guess how deep to seat it in the collet.

Enclosed bearings didn't seize up or burn my walnut tabletop

Nothing hurts worse than spending all weekend gluing and sanding a walnut tabletop only to have a cheap router bit bearing seize up and burn a pitch-black trench down the edge. The enclosed guide bearings on this Cosari set spin buttery smooth and don't choke on fine hardwood dust like the unshielded bearings on generic sets.

Finally a case that doesn't slice your thumb open

My old generic set had plastic sleeves so tight I sliced my thumb open trying to pry out the flush trim bit with pliers. This Cosari case has a smart layout where the bit rows hold the shanks securely but let you grab them safely, and having the exact profile drawing and fractional measurement printed underneath every single slot saves me 5 minutes of squinting before every cut.

Clean dados in 3/4 Baltic birch plywood with zero veneer splintering

Tested the 1/2-inch straight bit and the rabbet bit on three sheets of 3/4-inch Baltic birch plywood for shop cabinets. Zero veneer splintering on the top ply and the YG8 carbide stayed razor sharp through every abrasive glue line. Also comes with the Allen hex key right in the case so you can swap or clean a pilot bearing in 30 seconds.

Zero vibration or chatter in my Makita palm router

Put the roman ogee and 1/2-inch flush trim bit through their paces in my corded Makita trim router. Zero vibration or chatter. You can really feel the anti-kickback body design keeping the cut controlled, even when wrapping around tricky end-grain corners on white oak.

Finish carpenter approved—stays right in my truck box

I'm a finish carpenter by trade and keep this 15-piece 1/4-inch set in my truck box for hinge mortising, flush trimming laminate countertops, and easing stair treads. The shanks measure a dead-on 6.35mm and the carbide holds an edge right alongside individual bits costing 4x more.

Great bit quality, just remember to wipe off the factory oil

The bits arrive coated in a light protective machine oil so they don't rust in transit. Took me two minutes with a shop rag to wipe them dry before routing some cherry picture frames. The 45-degree chamfer and dovetail bits cut like a dream with zero tear-out.

No more collet slippage on heavy passes

I threw away my cheap yellow-painted router bits after one slipped up in my collet and ruined a cabinet door rail. Because these Cosari shanks are bare ground steel with no paint overspray, my collet grips them tight every time. Haven't had a single bit creep during a cut.

Covers every profile a home woodworker actually uses

Instead of 30 filler bits you'll never touch, these 15 profiles are the exact ones you actually use every weekend—4 straight bits, flush trim, roundover, chamfer, rabbet, cove, roman ogee, V-groove, mortising, dovetail, and panel pilot. Best $35 tool upgrade in my garage.

Frequently Asked Questions

Will the Cosari EdgePro 15 fit my router?

Yes, if your router takes a 1/4-inch collet. That covers palm, trim and many plunge routers from DeWalt, Bosch, Makita, Milwaukee, Ryobi, Craftsman and Skil, corded or cordless.

Which 15 bits are included?

Four straight bits (1/8, 1/4, 1/2 and 5/8 inch), R1/8 and R1/4 core box, 1/2-inch 45° chamfer, 1/2-inch flush trim, 1/2-inch mortising, 1/2-inch dovetail, 3/8-inch 90° V-groove, R1/4 cove, R5/32 Roman ogee, R3/8 roundover and 3/8-inch rabbeting.

Are the shanks painted?

No. The shanks are bare, precision-ground steel at 6.35 mm, so they seat cleanly in the collet. Only the cutter bodies carry the crimson PTFE coating.

Can I replace the guide bearings?

Yes. The bearings are sealed and held by a hex screw, and the hex key is included in the case, so swapping or cleaning one takes about a minute.

Will it burn hardwoods like oak, maple or walnut?

In our tests it left no visible burn marks on white oak or hard maple end grain at 18,000 RPM with a steady feed. Feeding too slowly will scorch any bit, so keep the router moving.

What if it doesn't work for me?

You have 30 days to use it on your own projects. If it chatters, burns, slips or a bearing seizes, return it for a full refund. Carbide tips and bearings are also covered by a 2-year warranty.
