StrikeMaster Lite-Flite Lazer drill bit (incl. blades & guard)

Measured in mm of diameter—the drill you choose depends on the fishing you’ll do:
90-130 mm suits perch and smaller fish like grayling, char, and trout in some waters
130-180 mm is good for general trout fishing
200-250 mm works for ice fishing for zander, pike, and other larger species.
