Topic tags/keywords: router bit 18 shank dremel sign making

Hey Folks!

So, I have just started dabbling in routing with a Dremel tool and Bosch Colt 1hp router. My purpose for now is making engraved signs for fun.

I am a total newbie who has bought some budget bit sets from Amazon to experiment with before investing in better quality bits.

Where would I buy 1/8 inch shank bits to fit my Dremel? Seems like a hard product to find.

Are there 1/4 inch shank bits that would allow me to do very fine engraving with the Bosch Colt? If so, what do you recommend to buy. Guessing I should be using straight bits.

So far I have only used some round over bits for outside edges and straight bits for inside plunge type routing. I believe I made dull the dremel straight bit with my first project. It really was a lot of routing for my first try.

Thanks for your help.

Search ebay for 1/8th router bits. I just got another set of them a month ago.

I thought every rotary bit Dremel sold was 1/8”. That’s all I have anyway.

Figure out which ones you need then google the bit # to find the best prices.

check out jewelers supply houses. They typically stock more variety than you’ll find at the big-box stores, and as well a lot of the more obscure Foredom accessories

I think Rio Grande is a major supplier south of the border.

Check dental supply dealers. I believe the dental bits they use have 1/8” shanks or 3/32” shanks which Dremel has a collet for. You could also contact your friendly neighborhood dentist for old bits they would just dispose of.

Dental supply is great for bits, just not the router bits he’s looking for.

Have your say...
