I installed these on my campus pedals, and now my "street" side is almost as surefooted as the clip-ins! And with way more comfortable footwear, to boot.
However, I found that no bit smaller than 5/64" would work. When using 1/8", the spikes stripped their threads instead of tapping. Maybe this depends on the pedal material.

These make a huge difference

I got these for my Thin Gripster pedals after reading the previous review. The Gripsters are nice but on the first really wet day with leather-soled dress shoes I was slippin' and slidin'. I put a few of these babies in and it was like night and day -- I felt absolutely locked in, with no straps or clips of any kind. On a gum or sneaker sole, they make less of a difference, but still better. If you ride in the rain, get some.
Note that the Gripsters don't need to be drilled; they already have spikes, just shorter ones.

Pedal spikes are a must for Portland, Ore. Rain

I purchased and installed these spikes about a year ago and they completely eliminated the shoe slipping issue I was having with my grip king pedals in the wet and muddy winters of Portland, Oregon. I just ordered another batch for my partner and to replace a few of the pedal spikes that have fallen out of my pedals. I think on this next round I'll use some bees wax or thread lock to keep 'em in. :^)
Russ Roca from the pathlesspedaled also has a great review of similar RivBike pedal spikes on his blog epicureancyclist.com. Cheers!
