3-1/2" HSS Bimetal 8% Hole Saw
- Perfect round back plate.
- Fast & easy center drill change.
- Thick steel body.
Bimetal Plus 8% Cobalt
Premium bi-metal with 8% cobalt provides Xtreme results in performance and up to 50% longer lifetime than the competition.
Special tooth geometry with regular pitch provides a smoother cut and better chip clearance preventing clogging and heat build-up. Teeth are alternate & side set to minimize binding and friction, requiring less feed pressure.
- Metals (up to 1000 N/mm2 strenght).
- Mild steel.
- Stainless steel.
- Non-ferrous metals, aluminium.
- Sandwich materials.
- Cast Iron.
- Copper, zinc, brass.
Speed kills!Operating at higher speeds than those recommended will shorten hole saw life and produce very inefficient cutting.
Feed pressure:variables in material, work configuration should be considered. Apply sufficient feed pressure to aid good chip removal. Reduce the pressure when hole saw becomes hot or if teeth start to clog with material. Insufficient feed pressure will dull tooth points prematurely, but too much pressure can totally destroy teeth.Operating at higher speeds than those recommended will shorten hole saw life and produce very inefficient cutting.
Cooling lubricant:Cutting oil serves several purposes when sawing in metals. It cools saw and workpiece, reduces heat and abrasion, which can shorten cutting lef, also aids removing sward from the cutting surface.Using a cooling lubricant will extend your hole saw life by 500%.
California Proposition 65
⚠WARNING: – www.P65Warnings.ca.gov.
We are providing this warning pursuant to a law passed by California in 1986 called the “California Safe Drinking Water and Toxic Enforcement Act of 1986”, or “Proposition 65” for short.
A Proposition 65 warning does not mean a product is in violation of any product-safety standards or requirements. In fact, the California government has clarified that “[t]he fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.”
The California agency tasked with implementing Proposition 65 has also explained, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.” See http://oehha.ca.gov/prop65/background/p65plain.html
