CM65-15 Asphalt Milling Bit Wear Guide For Road Milling Machines And Pavement Cutting Cost

CM65-15 Asphalt Milling Bit Wear: Why Pick Life Decides Your Cost Per Square Metre

On a cold planer or road milling machine, the milling bits are the cheapest component on the machine and the most expensive one to get wrong. One dull pick does not just cut slower - it drags, heats up, wears the holder and pushes the whole drum into a higher cost bracket. This guide explains how the CM65-15 asphalt milling bit behaves in service, how to recognise wear before it costs money, and how to plan pick consumption so that tooling cost per milled square metre stays predictable.

What Happens When A Milling Pick Goes Dull

A road milling pick cuts by impact and rotation, not by slicing. The tungsten carbide tip breaks aggregate while the steel body spins in its holder, so wear stays even around the tip. Once the carbide loses its profile, three things follow in sequence:

• Cutting resistance rises: the drum needs more power for the same depth, and machine output drops.
• Heat builds up: extra friction travels into the holder, and holder bore wear becomes the next repair.
• Surface quality falls: the milled texture becomes uneven and torn, and more hand work is needed before paving.

By the time an operator notices the machine struggling, the picks are usually well past the point where replacement would have been cheaper.

Wear Stages Worth Checking On Every Shift

Why The CM65-15 Pick Holds Its Edge

• Tungsten carbide tip: the carbide insert keeps a cutting profile far longer than steel, so the drum holds depth instead of smearing the surface.
• Hardened steel body: the shank absorbs impact from aggregate and reinforcement without deforming in the holder.
• Retaining ring fit: the ring keeps the pick seated and rotating correctly, which is what prevents one sided wear.
• Quick change design: picks are pulled and refitted with standard tools, so a worn pick is swapped in seconds rather than at the end of the shift.

Technical Summary

Planning Pick Consumption

Tooling cost is easiest to control when picks are treated as a consumable with a known rate, not as an emergency purchase:

• Record picks used against milled area, not against machine hours.
• Keep a minimum stock on site equal to one drum set plus ten percent.
• Replace seized picks immediately rather than at shift end, to protect holder bores.
• Check holder rotation by hand during every refuelling stop - a pick that will not spin is already costing money.
