Makita 450245-4 Spare Part - CHUCK COVER HR3210CT/FCT
Makita 450245-4 — Chuck cover (genuine Makita)
Keep the nose of your rotary hammer sealed and working like new with this genuine Makita chuck cover (part no. 450245-4). Designed to seat over the tool’s front nose, the flexible elastomer cover shields the chuck assembly from dust, grit and masonry debris that accelerate wear and can foul bit changes. It's a direct replacement for the original cover listed in the HR3210C parts breakdown.
Key details
- Part number: 450245-4 (Makita chuck cover for HR3210C).
- Function: protective nose/chuck boot that fits over the tool’s chuck area to help keep abrasive dust and particles out of moving parts.
- Construction: durable rubber/elastomer material that flexes for easy installation but resists tearing and abrasion on the job.
- Installation: push‑fit onto the tool nose — no special tools required; designed to hold securely while allowing normal bit changes.
Typical fitment
- Commonly used on Makita rotary hammers in the HR3210 series, including HR3210C and HR3210FCT. Many SDS chuck repair kits for these 32 mm machines include this cover as the direct replacement.
Why replace it
If the original cover is cracked, split, or loose you’ll notice more dust ingress and stiffer or jammed bit changes; replacing the cover restores the intended seal and helps prolong the chuck and internal components’ service life. This genuine Makita part matches the original fit and finish, so it installs cleanly and performs the same as the original component.
