Apollo 2642532 A7-20 Strengthen Pick Milling Bits Cutter Teeth for Road Milling Drum 7mm Gasket

The Apollo 2642532 is a 7/20 strengthen pick used in the milling drum of road milling machines. The 7mm gasket seat and the reinforced shoulder separate it from the standard 20mm pick body, and that combination is what allows the tool to survive higher impact loads in hard asphalt and in drums that run slightly aggressive cutting geometry. It is supplied with the matching gasket so the pick seats correctly in the holder from the first fit.

Standard picks work well in uniform asphalt. They lose life quickly when the drum meets milled joints, patched areas, reinforced concrete base or grit with a high aggregate content. In those conditions the shank shoulder takes the shock rather than the carbide tip, and a standard pick either snaps at the shoulder or spins in the holder and wears the bore. The strengthen pick moves material to the shoulder area, keeps the tip in contact with the surface, and protects the holder bore, which is the expensive part to replace.

• Flattened carbide tip: the tip no longer forms a point, cutting speed drops and the drum starts to smear instead of cut.
• Visible shoulder wear: a groove appears behind the tip, which means the holder bore is starting to take load.
• Loose pick in the holder: the retaining ring no longer holds, and the pick rotates freely by hand.
• Rising vibration and fuel use: a drum with dull or broken picks pulls harder and shows up as higher consumption per square metre.
• Rough milled surface: the pattern becomes irregular and the depth control starts to be corrected constantly by the operator.

• Reinforced 7/20 body: thicker shoulder area takes impact load before the carbide tip does.
• Hardened steel shank: holds its diameter in the holder, which protects the bore from oval wear.
• Carbide tip brazed in position: the cutting point stays centred under load, so the pick keeps cutting instead of skidding.
• 7mm gasket included: correct seating height and preload without measuring or shimming on site.
• Bulk-friendly supply: packed in boxes on pallets, so drums can be re-tipped in one operation rather than in ones and twos.
