About Re-Load Deep Cut HSS
HSS stands for High Speed Steel
Construction is Bi metal (two metals) being HSS teeth + alloy strip (blade backing).
The HSS and alloy strip were originally electron beam welded together but increasingly Lasers are used.
Only the top 3 to 4mm of a Bi metal hole saw is HSS hence the reason why the hole saws have limited re-sharpening life.
Cobalt can be alloyed with the HSS to make it harder and more resistant to heat.
However the addition of Cobalt increases costs.
All Re-load Hole saws include Cobalt as standard right across the range.
TIPS
AVOID excessive speed as the heat generated will cause a loss of hardness in the teeth.
Use cutting compound to preserve tooth life.
Avoid breathing compound fumes during cutting.
Ideal for sheet metal, stainless, cast iron and mild steel.
