Where a ripper works in mixed ground, the 9W4551 Wear Cap Tip covers both penetration and wear. The nose is cast slightly proud of the shank line so the tooth, not the shank, absorbs abrasion, and the body is held at 49-56 HRC through section.

Typical duty: heavy rock ripping on single-shank rippers plus secondary breaking, where the tip must survive both abrasion and shock loading.
Spectro analysis of the melt, pour temperature log, normalising and tempering cycle record, hardness sampling at three points per batch, dimensional check on the pin hole and nose profile, then visual and shot-blast finish inspection before packing.
Standard export packing is anti-rust paper plus woven bag on a fumigated pallet. For sea freight we add corner protection and steel strapping; for air freight we use double-wall cartons so the tip edge cannot cut through the box.
Nose width 70 mm, pin hole 24 mm, unit weight 10.0 kg and overall length 435 mm. Supplied bolt-on wear cap as standard, normalise plus temper treatment, 60 pcs per pallet, reference wear life around 350 hours in medium abrasive rock. Lead time 7-15 working days, MOQ 100 pieces.
