Freud 8 Piece CNC Router Bit Signmaking Set Guide: Types, Uses, Sizes, and Selection Tips

Most sign makers assemble their bit collection the slow, expensive way: buy a bit for a job, discover it is the wrong profile, buy another, and repeat until a drawer fills with near-misses. A curated set skips that tuition. The Freud 87-108 8 Piece CNC Router Bit Signmaking Set is exactly that kind of shortcut, a bundle chosen specifically for the cuts signmaking actually needs, so you start with the right profiles instead of learning them one mistake at a time.

The Freud 8 Piece CNC Router Bit Signmaking Set (model 87-108) is a 1/4 inch shank collection of solid carbide and carbide-tipped bits built for lettering, engraving, and relief in wood, plastics, and composites. This guide breaks down what is in the set, what each bit does, the sizes involved, and how to decide whether a curated set like this fits how you work.

What is in the set

Freud’s 87-108 set includes eight bits chosen for sign work, all on a 1/4 inch shank:

• Two up-cut spiral ball nose bits (solid carbide) for smooth 3D and relief carving.
• A 1/32 inch tapered ball tip and a 1/16 inch tapered ball tip (solid carbide) for fine detail and small lettering, with the taper adding strength.
• An up-cut spiral (solid carbide) for general clearing and cutouts.
• A down-cut spiral (solid carbide) for clean top surfaces on lettering and edges.
• A 3/4 inch 90 degree V-groove and a 1/2 inch 60 degree V-groove (carbide tipped) for V-carved lettering at two different angles.

Freud builds these with its TiCo hi-density carbide and a Black I.C.E. coating that the company says runs cooler and clears chips better, for longer edge life than uncoated bits.

What each type does in sign work

• V-groove bits cut the crisp, pointed lettering that defines a V-carved sign. Two angles give you flexibility: a 90 degree for wider, shallower letters and a 60 degree for narrower, deeper ones.
• Ball nose and tapered ball tip bits handle 3D relief and fine detail, blending contoured surfaces and reaching into small features.
• The up-cut spiral clears chips fast for pockets and cutouts.
• The down-cut spiral protects the top face, which matters when the sign surface is the show face.

Between them, these cover the three pillars of sign work: lettering, relief, and clean cutouts.

Sizes and compatibility

Every bit in the set uses a 1/4 inch shank, so your machine needs a 1/4 inch collet, which is standard on most hobby and prosumer routers. Confirm your collet size before buying, since a 1/4 inch shank will not fit an 1/8 inch or a 6mm collet. The set spans from fine 1/32 inch tapered tips up to a 3/4 inch V-groove, which is a wide enough range to cover most sign lettering and relief without extra purchases.

Selection tips: is a set right for you?

A curated set makes sense when it matches your work. Consider:

• Buy the set if signmaking is your focus, because the profiles are chosen for exactly that and you avoid piecemeal buying.
• Skip it if you already own V-bits and spirals, since you may only need one or two specific profiles rather than a whole bundle.
• Confirm the 1/4 inch collet on your machine first.
• Treat the fine tapered tips as consumables, because small-diameter tips are fragile and will eventually break.
• Pair it with a surfacing bit, which sign work needs and the set does not include, for flattening boards and spoilboards.

The Freud 87-108 set is sold through woodworking retailers such as Rockler and other Freud dealers. Confirm the exact model number (87-108, the signmaking set) at purchase, since Freud also sells a similar 8 piece general purpose set (87-208) with a different bit selection.

The honest verdict

The Freud 87-108 is a sensible starter bundle for someone whose main work is signs, because the eight profiles genuinely map to lettering, relief, and cutouts, and Freud’s carbide and coating are a step above bargain bits for edge life. It is less compelling if you already own the common V-bits and spirals, since you would be paying for overlap. Confirm your collet is 1/4 inch, treat the delicate tapered tips as wear items, add a surfacing bit, and this set gets a sign maker cutting the right way from day one.

Frequently asked questions

What bits are in the Freud 87-108 signmaking set? Two up-cut ball nose bits, 1/32 inch and 1/16 inch tapered ball tips, an up-cut spiral, a down-cut spiral, and 90 degree and 60 degree V-groove bits, all 1/4 inch shank.

What shank size does the set use? All eight bits have a 1/4 inch shank, so your machine needs a 1/4 inch collet, which is standard on most hobby and prosumer routers.

Is the Freud set good for V-carved lettering? Yes. It includes both a 90 degree and a 60 degree V-groove bit, giving you two angles for wider or narrower lettering, which covers most V-carved sign work.

What is the difference between the 87-108 and 87-208 sets? The 87-108 is the signmaking set, and the 87-208 is a general purpose set with a different bit selection. Confirm the model number so you get the profiles you want.

Do I need anything else for signmaking? A surfacing bit for flattening boards and spoilboards, which this set does not include, plus a machine with a 1/4 inch collet and good workholding.

Are the fine tapered tips fragile? Yes. The 1/32 inch and 1/16 inch tapered ball tips are delicate by nature. Treat them as consumables, since small-diameter tips break with use.

Is a curated set better than buying bits individually? It is if signmaking is your focus, since the profiles are pre-selected and you avoid piecemeal buying. If you already own V-bits and spirals, individual purchases may serve you better.
