Komatsu PC300 Rock Chisel Tooth

This Komatsu PC300 rock chisel tooth is a non-OEM replacement excavator bucket tooth for compatible PC300 bucket tooth systems. Cross-referenced to part number 207-70-14151RC, it features a rock-chisel profile for demanding excavation where penetration and resistance to abrasive wear are important.

The chisel-shaped tip concentrates digging force into the material, helping the bucket break into hard ground, compacted soil, rock, aggregate and quarry material. This makes it a practical choice for heavy earthmoving, construction, quarrying and excavation work where a general-purpose tooth may provide less effective penetration.

Bucket teeth are consumable ground-engaging wear parts. Replacing teeth that are rounded, cracked, worn thin or loose can help maintain digging performance, protect the bucket lip and reduce premature wear to the adapter and locking system.

Before ordering, check that your bucket uses the compatible Komatsu PC300 tooth system. Compare the tooth profile, adapter fitment and locking arrangement with the existing component, and use reference 207-70-14151RC as a cross-check. Matching pins and retainers may be required separately, depending on your bucket setup.
