carbide tipped hole saw
 
Hi,

Does any one know where I can get a good carbide tipped hole saw?

I'm fed up of mine breaking or just losing it's sharpness.:furious:

I broke down and bought this set.
It cuts way faster then an hole saw I've ever used before.

some big box stores will hve them, however your better off going to a tool dealer that caters to contractors in your region.. if that wont work try online

I hate buying kits...
I'll assume that the mandrel portion is the same as other hole saws...
and I have a preference for Lenox.

Buy what you *need* when you need it.

while yes, those do really chew though some wood, they are also quite a bit rougher than many other hole saws, i wouldn't really want to use it for any finish work.

Might be overkill but if you are shopping for carbide you might as well at least price diamond. And before they all disappear, support your local sharperner for saw blades and drill bits. I rotated mine through on a regular basis, got chimp change pricing, had new bit and blades trued for free so they spun without wobble, and get free pick of the bits and blades people never came back to claim. I have great wood blades as a result.

I tend to dislike kits of any kind also. Buy the hole saw you need and not the six that come in a kit you will never use. And skip the switchable shank things. Pay the piper. Buy the nicely tooled hole saw as a unit, at a real tool store.

Should be asked? What your you putting holes in, what size, and really how often? Why are you dulling hole saws, unless they are cheap, at such a rapid pace?

i forgot to mention,, that the need for carbide is solely based on the material you are drilling through.. im a carpenter by trade and just use regular hole saws, most often bosch or milwaukee. all i need hole saws for is for locksets in doors, pipes in the back of cabinets im installing or for electrical boxes coming through siding..

my electrician uses dimaond hole saws for cutting holes in plaster walls when he has to fish wires in older homes.. he claims he can easily drill 3-400 holes on one saw before its dead... compare that to a regular saw and your looking at maybe 25 holes

Diamond is nice and usually the supporting structure fails before time before the cutting edge ever will.

We both agree. What are you cutting holes in, how often, and why are you dulling your cutting tools so fast. I have a hole saw, shared shank thing my grandfather gave me. I think parts of it have been used a couple times. I never even think to reach for the clunky thing.
