Important Product Questions
Do I sharpen this blade when it is dull?
The SWITCHBLADE system is designed to restore the cutting edge by replacing the blade. Use the correct replacement size for the bit body.
Can I change the hole size by fitting a different blade?
Match the blade’s engraved size to the bit body. A different-size blade is not a substitute for the correct bit.
What else should I inspect when changing blades?
Check the feed screw, blade seat and retaining fasteners for wear or damage. Isolate the tool and follow the replacement instructions.
