Deeeeep Holes

A lot longer than I needed, but gets the job done.

Irwin woodboring drill bit

Used it for pressure treated lumber for landscaping, bored a perfect 4” deep hole no issues in any of the 60 drills

Good drill bit

Sharp and drilled very well. Good price

Running phone wire

Great to bore through wall and pull phone wire back through the hole you drilled. Small whole in woodbore allows you to hook wire to it to pull it through wall with little to know trouble. Works great.

More than a little bit

Drill bit used to drill hole for lamp cord. It worked great and lamp works great. This lamp is a keep sake that was made from raw cedar that he had cut down as it had overgrown the area it was located. He had turned it on a lathe but ran the cord down the side of the lamp which caught on everything. The drill gave me the opportunity to drill the lamp and using a router, groove the base to allow the cord to exit the bottom of the lamp.

Drill bit

The bit does everything I need it to do and with its length it has the ability to reach the deep spots.

Drilling holes in a deck and for cable railing

We used this bit to drill through 6x6 posts for cable railing. It worked really well in all situations, great results. By the end of the project the neck of the bit was slightly warped. Likely because we were pushing too hard.

Great product. Hard steel doesn’t dull easy. Used it in raw timber.
