Milwaukee ice hardened products utilize a proprietary
cryogenic hardening process that improves upon traditional heat treat
processes. Unlike surface coatings that wear away, cryogenics Harden to the
core by minimizing soft metal (austenite) and creating more hard metal
(martensite). the result is a product that is more consistently hard
throughout, resulting in life up to 50% longer than the competition. From the
Manufacturer Milwaukee Electric Tool Corporation introduces Ice Hardened hole
saws, a new generation of hole saws that offer up to 50% longer life than the
competition and are ideal for metal and wood cutting in a wide variety of
HVAC, electrical, plumbing and maintenance/repair applications. Milwaukee Ice
Hardened products utilize a proprietary cryogenic hardening process that
improves upon traditional heat treat processes. Unlike surface coatings that
wear away, cryogenics harden to the core by minimizing soft metal (austenite)
and creating more hard metal (martensite). The result is a product that is
more consistently hard throughout, resulting in life up to 50% longer than the
competition. Milwaukee Ice Hardened hole saws also feature Matrix II bi-metal
construction for greater durability and a unique precision-ground tooth
geometry for faster cutting. A positive rake angle cuts more aggressively
while deeper gullets quickly remove chips. A radiused back face reduces stress
on the teeth, ensuring that the blade delivers optimum life and speed.
Functional slot geometry allows for a standard slotted screwdriver to fit
completely underneath the plug for easier plug removal.
