Our aftermarket full sets of Komatsu D275 crawler dozer Cutting Edge & End Bits replacement are bolt-on GET wear parts specially designed for D275 crawler dozer buckets. The Komatsu D275 crawler dozers are widely used in open-pit overburden stripping, mass earthmoving, dam construction, mine waste hauling, weathered hard rock excavation and large port & airport site grading, capable of long-hour continuous full-load operation.

There are mainly 4 raw material options :

1. 30MnB Boron steel : use most, hardness is about HRC 440–500,can balance toughness and wear resistance well,it is ideal for sand, gravel and earth works.

2. C80 Carbon Steel : it is economical, hardness can reach HB280–360 after quenched and tempered, Suit for pure earthmoving and loose material handling, not fit rocky and high-impact sites.

3. NM400/NM450 alloy steel : own superior anti-scouring and wear resistance compared with boron steel, has greatly extending service life for long-term gravel, aggregate and construction debris working scenarios.

4. Mn13 high manganese steel : own work-hardening property, the surface will get harder under continuous impact. It fits occasional rock and hard impact. Not economical for pure earthmoving.

To ensure stable quality,our factory execute strict quality inspection during our entire process :

1. Material Test: use spectrometer inspection to verify chemical composition , ensure alloy elements like carbon, chromium and manganese meet standard.

2. Hardness Test: adopt random Rockwell hardness test,ensure uniform hardness for cutting edge and end bits and working surface reaches required hardness while maintaining proper toughness to avoid brittle fracture.

3. Dimension Inspection: we will check overall length, thickness, bolt hole pitch and bevel angle, and control tolerance within industrial standard.

4. Visual & Magnetic Particle Inspection: no cracks, porosity or laminations. No chipping on cutting edge and no burrs around bolt holes.

5. Sampling Impact Test: our technician will simulate working impact to verify anti-breakage performance.

Welcome to contact us for more detailed information.Normal production lead time: 25– 35 working days upon receipt of deposit.To quote precisely, please share your loader model, OEM part numbers for cutting edge & end bits, plate thickness, required bevel type, end bit style,we can provide material and hardness test report with stable lead time.
