Customer Comment:
I am using the 0.75 mm WPI punch for punching 
flow inlets in microfluidics chambers molded of 
PDMS (polydimethylsiloxane). I have made around 
75 hole punches with a single unit into PDMS, the 
blade and the extractor still work perfectly...  I find 
the blade to be noticeably sharper than the Harris 
equivalent, as well as being more ergonomic, in 
my opinion, with the feel of a pen or pencil in one's 
hand.
