What size bit do you use for drainboards? I have seen them with a skinny core box bit and also a wide bit up to 1″. Just curious what you all used.

Andy,

I use a 5/8″ dia. with rounded corners. I like to cut 1/16 deep on the shallow end and 3/16″ deep nwhere it enters the bowl. I do not add reinforcing under the drain board and have not had any problems.

Andy,

We use this type of bit and mostly use the 1/2″ dia. The bits shown are 1/2, 5/8, 3/4, & 1″. We will cut ours from 0″ to 1/4″ in depth.

We use a 3/4″ as a standard, but have done 1/2″ and 1″

Want a really cool effect?? Do a 1/4″ stripe inlay in the drainboard. Looks sharp. Let me see if I have a picture….

Matt, I’ve seen something like that done and you’re right, it is very cool! Hope you have some pics to post.

Don’t leave me hangin, I need to see a picture of this. I get a lot of comments about drainboards about things might tip over if the groove is too wide. The 1/4″ bit my be the answer.

Does it need to be that wide, 1/4″? Would the water bead up and block the flow or something?

[Andy Graves]

Matt,

Were you able to find a picture of that Drainboard with the 1/4″ bit? Just curious

[Gordon Shell]

Not trying to spam, here is a deep drainboard done in 3cm, pretty wide bit.

[Andy Graves]

Gordon,

Do you happen to know what size bit that is?

[Matt Kraft]

Andy,

Couldn’t find one, but I will take one today and get it posted.

I believe the bit that was used on the EOS pic is a 3/4 cut with an 1/8″ radius in the corners. Dave has one in the Velepec catalog.
