Bimetal hole saws
551
TECHNICAL FEATURES:
• 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.
Tooth design
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.
Application
Materials:
-
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.
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%.

Percussion/hammer action mode must be turned off when using these hole saws.
