Caterpillar 40 series rock penetration tooth

This Caterpillar 40 series rock penetration tooth is a replacement excavator bucket tooth for attachments using the CAT 40 series tooth system. Cross-referenced to OEM part number 7T3403RP, its rock-penetration profile is designed for work where breaking into hard, compacted and abrasive material is a priority.

The pointed tooth shape concentrates digging force towards the tip, helping the bucket penetrate rocky ground, compacted soil, aggregate and quarry material. This makes it a suitable profile for demanding excavation, earthmoving, construction and quarrying applications where a broad general-purpose tooth may offer less penetration.

Bucket teeth are consumable ground-engaging wear parts, and timely replacement helps maintain digging performance. Replacing teeth that are rounded, cracked, worn thin or loose can help protect the bucket edge and adapter system while reducing unnecessary load on the excavator.

Before ordering, confirm that your bucket uses the Caterpillar 40 series tooth system. Compare the existing tooth profile, adapter and locking arrangement with your current part, and use OEM reference 7T3403RP as a cross-check. Compatible pins and retainers may be required separately, depending on the bucket setup.
