A client operating a high-horsepower, half-lane road milling machine to remove asphalt was interested in comparing existing supplier’s
picks to Kennametal’s Road King series. The client wanted to know how both sets of tools stacked up in terms of lifespan, body wear,
carbide wear, and retainer and washer wear.

MEET THE ROAD KING RK52

Our RK52 road rehabilitation pick is precision-engineered
for durability and cutting strength, combining superior
holder protection and easy penetration to drive
exceptional machine performance.

ROAD TEST CONDITIONS

The client decided on a split-drum comparison, with 100 RK52 tools placed on the right side and the incumbent supplier on left side of the 2.2m milling drum. The drum was of average mid-life condition, and its OEM holders showed significant yet consistent wear across the drum to still leave a nice pattern. The test was conducted over two days in October 2023, with rain and wet surface conditions the entire time. Two inches of hard asphalt road surface were removed over a distance of 30,000 feet, with both sets of tools checked by the milling machine’s operators at the middle and end of each work day.

• Tool Lifespan — Both sets of tools performed similarly and were changed out at the same time towards the end of the second shift,
but four non-Kennametal picks experienced premature breakage.
• Body Wear — RK52 tools showed desired hourglass shape indicating extra clearance and holder protection.
• Carbide Wear — As the picks began to work, the RK52 sharpened fi rst and then both styles cut and wore in the expected shape.
All picks were changed before completely losing their cutting point.
The machine operators preferred how the carbide tip in each RK52 pick resisted wear. And based on their experience,
they believed RK52 could last even longer under different conditions!
