« Part 8: Slow week Part 9 of Building a new workbench series Part 10: Time to install the tail vise »

After buying the 3/4” Colt Maxicut forstner bit, I still wasn’t happy with my hole boring operation. The Maxicut is great, but I just felt that for holes almost 4” deep there had to be another option. I ended up buying another Colt product – their Twinland Brad Point bit. THIS was the answer I was looking for! This bit hogs out a nice clean hole and the leaves smooth exit as well.

Next I had to decide how to best drill the 1 1/2” holes for the screws on the Veritas Twin Screw Vise – I ended up trying an “Irwin Speedbor 1 1/2 spade bit. I’ve not had much luck with space bits in the past. They normally leave a really rough hole and a terrible exit. I was very pleasantly surprised with the Speedbor bit. As log as I slowed the feed rate at the entry and exit it was very smooth with little/no tearout. Here’s a picture of both holes in my scrap.

Now that I have the proper boring bits it’s time to turn to vise installation.
