Sometimes, drilling plastic can be difficult.
An: engraving/end mill/spoon/D bit can make this task easy and safe.
Chuck your bit in an electric drill or cordless screw driver.
At slow speed, advance the bit into the plastic.
These bits cut clock wise. (looking from the drill to the hole)
The single fluted bit cuts thin shavings as it advances.
Since the bits are tapered, you can drill smaller holes than the bit diameter, if you drill partly through the plastic.
However, the hole will be tapered.
These bits are made of carbide steel, avoid forcing the bit as this may result in the bit breaking.
And, these bits are SHARP!
Different bit degees available, 10,15,20 and 30°.
1/8" bits are ~$1.00 each.
