Frequently Asked Questions

Q: Which circular saw models is this blade bolt and flange set compatible with?

A: This replacement set is compatible with the DC390, DC310KL, and DCS391 circular saw models. Always cross-reference your saw's model number and the part numbers (Inner Flange 610046-00, Outer Flange N621119, Blade Bolt 648697-00) before purchasing to confirm fitment.

Q: What is included in the circular saw flange set package?

A: The package includes three components: one inner flange (Part # 610046-00), one outer flange (Part # N621119), and one blade bolt (Part # 648697-00) — everything you need to complete a full blade-mount hardware replacement.

Q: What material are the inner flange, outer flange, and blade bolt made from?

A: All three components are constructed from durable metal, ensuring they can withstand the torque and vibration of regular circular saw use while maintaining a secure blade hold.

Q: How do I install the replacement flange set on my circular saw?

A: Always consult your circular saw's user manual for blade-changing and hardware-replacement instructions specific to your model. Ensure the saw is unplugged or the battery is removed before performing any maintenance. The inner flange fits onto the arbour first, followed by the blade, the outer flange, and finally the blade bolt to secure everything in place.
