Has anyone used a Wixey laser cross hair adaptor for a drill press? I can buy one at Rockler for $37.50 or buy a new powermatic drill press for $1500 or do nothing.

My Delta DP came with one. Unless they have gotten a lot better, I
would not advise getting one.

I never ever used it. I felt that a laser on a DP would be as useful as
using one on a sander, or hammer. ;~)

You do have to actually drill a hole at some point, let the bit be your
pointer.

If you need to pin point a location before hand, use a 1/16" bit to line
things up.

Or use a brad-point bit.



That too, but a smaller one. If drilling at an angle the spurs on a
larger brad point bit can prevent the point from touching the exact
spot, for initial alignment.

I had that issue when using drilling these holes for wine bottle stoppers.

But a smaller bit defeats the purpose of the brad. If you have to
drill at an angle, use a Forstner bit. ...or just use a twist drill
and be done with it.



The small bit was for alignment only. The spurs on the 1/2" brad point
bit cut into the wood, at an angle, very much like a Forstner bit. The
bottles being drilled sat in a cradle.

But if the brads touch the wood before the pin, a pilot hole isn't
going to do a thing. The pin won't do anything either. Might just as
well use a twist drill.

With a 1/2" bit no deflection so no pilot hole needed. A regular bit
will not cut as cleanly at the entry point as a brad point bit.



Also, there are only two brads so the bit will tend to "walk". A
Forstner but won't "walk". A Forstner is a better choice.


And yet, I had no issue with the bit doing anything but go straight down
and into the wood. The spurs were cutting cleanly before the brad
point. Like a Forstner bit.

I will say however that I was using the Colt 5 Star brad point bit.
Those bits 1/4" and larger, cut through a piece of wood with no backer
board and do not tear out on the back side when the bit goes through.
