Undercoating Hole Drill Bit For Undercoating Plugs

When I ordered this bit I was hoping it would be of high quality, and it was. It was an Irwin- Made in USA.

This is useful for gaining access to inside body areas such as doors and pillars. High quality tool.

It's to bad I didn't know about this hole drill bit previously. The bit makes nice clean 0.5 inch holes for the body plugs. So far we have used one on four cars and it works perfectly. Never use a standard drill bit again.

Drilled clean holes for the plugs in my Ford Crown Vic. The plugs fit snug and are water tight. These are a must have for rust proofing & buying this bit & the plugs together is the best way to go. With this I was able to apply Fluid Film into the insides of the doors and lower rockers giving my car awesome rust protection. Applied in the heat of August to give the film time to settle into all the crevices. With these plugs in place next year it will go much faster. I highly recommend this product.
