PRODUCT DESCRIPTION
You’ll work at peak performance for even longer when you use these HSS-Ground Thunderweb drill bits from Milwaukee. The Milwaukee Thunderweb design is characterized by a conical shaped web which gets thicker towards the back of the drill bit. Standard drill bits have a constant thickness throughout their length. Even at the narrowest point the Thunderweb core is thicker than that of a standard drill bit. The web is the internal core of the drill bit.
