Curved cutting edge for Caterpillar motor graders, replacement for part number 4T2242. Dimensions 2133 x 203 x 25 mm — 7 ft x 8 in x 1 in — with 15 holes at 5/8 in to the CAT hole pattern. Single piece weight is 79 to 81 kg depending on the source.
The curved profile cuts better than a flat edge and carries material along the moldboard, which gives more even grading — it is the preferred edge type on motor graders. Choose a thinner edge for light abrasion and low impact, a thicker one where abrasion or impact is heavy, to gain strength and wear allowance.
Hole count has to match the moldboard: a 15-hole edge cannot be used on a 13-hole machine. The edge is through-hardened carbon or boron steel and is best replaced together with the end bits.
Hardness figures differ widely between sources for this part number — from HB260 to HB500 — so we quote the actual hardness grade of the batch supplied. Please state the grade you need; otherwise the hardness difference alone can turn into a quality dispute.
