Paving Breaker Blade Tools: Asphalt Cutters, Clay Spades & Wedges

Turn a paving breaker into a cutting and digging tool with wide blade steel. Tarmac and asphalt cutters, keen kut blades, frost wedges, clay spades, and plug-and-feathers shanks slice pavement, break frozen ground, and split rock, all sized for the breakers in our paving breakers & jackhammers range. Most blades come in every breaker shank from 7/8 x 3-1/4 to 1-1/4 x 6 in., and the fitment chart below shows exactly which sizes each tool ships in. For points, chisels, and the rest of the steel catalog, see tool steel.

Blade Tools by Job

Cutting pavement: the asphalt cutter is the all-around blade for scoring and cutting asphalt, while the wide tarmac cutter and keen kut blade make long clean cuts under heavier 60–90 lb breakers, and the asphalt wedge lifts cut sections. Digging: 5-1/2 in. and 4-1/2 in. clay spades and the digging chisel excavate clay, hardpan, and trench walls. Frozen ground and demolition: the frost wedge (12 and 17-1/2 in.) opens frozen ground, the concrete buster (14-1/2 and 36 in.) breaks slab, and the brick removing tool pops brick and block. Surface prep: the bushing tool textures and levels concrete. Rock splitting: plug-and-feathers shanks with matching feathers split stone from 1-1/2 and 2 in. drilled holes.

Blade Tool Fitment by Shank

Like all breaker steel, blades are not interchangeable between chuck sizes — match the shank to your breaker before ordering. Note the tarmac cutter and keen kut run only in heavy-breaker shanks.

Matching Blade, Breaker, and Job

Wider blades move more material but need more breaker behind them — run the 5-1/2 in. spade and the wide cutters on 60–90 lb machines, and step down to the 4-1/2 in. spade or asphalt cutter on 30–40 lb breakers and harder ground. For starting breaks and trenching with points instead of blades, see points & chisels; to set posts, pipe, and ground rods, see driving tools. Sizing the breaker itself? Our paving breaker buyer’s guide guide matches breaker weight to the work. Keep every shank coated with chisel paste to protect the front end.

Common Questions

What is the difference between a clay spade and a digging chisel? The spade’s wide curved blade lifts and moves soil; the digging chisel is narrower and penetrates compacted ground the spade would skate over. Crews digging mixed ground usually carry both.

How do plug and feathers split rock? Drill a 1-1/2 or 2 in. hole, insert the two feathers, then drive the plug between them with the breaker — the expanding wedge action splits stone and concrete along the hole line without flying debris.

Do blade tools fit every jack hammer? No — the shank must match your breaker’s chuck, and two of the blades here only come in heavy-breaker sizes. Check the fitment chart above, or the shank chart on our tool steel page to identify your chuck by breaker model.
