Carbide Bit Protector
Carbide is a hard material, but it's also brittle. Protect your carbide-tipped bits with this tip.
Carbide is a hard, long-lasting material, but it's also brittle. The carbide tips on a router bit or saw blade can be damaged easily if mishandled. To protect them, I keep an old computer mouse pad upside down on my bench. The spongy surface keeps the cutting surfaces safe and retards rollaway router bits.
