The drill made the job of drilling acrylic plexiglass much easier. Very glad we purchased this item.

Tangee always provides excellent service. The drill bits work well.

Worked perfectly. I used a 1/8 bit to pierce the acrylic then stepped up with standard bits, which seems to work fine. Would suggest not drilling thru with the larger bits bit drilling part-way thru and then re-drilling from the other side. This should prevent breakout. This seems to be pretty fresh acrylic and didnt have any tendency to shatter.

Love this bit --- cuts thru plexiglas like a hot knife thru soft butter. No burrs. Very clean. Only downside is that they dont come in gauge sizes

I used the 1/8 and 5/32 bits to fabricate and drape form a two piece windshield. They worked great, along with Bosch T102BF plexiglass cutting jig saw blades. Took the terror out of working with acrylic sheet.
