Progressor tooth geometry for super-fast cutting action
Editorial Review:
"POWER CHANGE" HOLE SAW SETS
Pilot bits easily snap into the mandrel without set screws and a threadless design prevents seizing up in the mandrel. The system also features a positive lock design to minimize wobble, a common problem with conventional mandrels. The Power ChangeTM mandrel accepts any 1/4" hex shank power accessory including spade bits and power screwdriver bits. Simply snap the hole saw off the mandrel for easy plug removal. When the cup is re-attached to the mandrel, the pilot drill will push the plug out Power ChangeTM bi-metal hole saws feature Progressor® tooth geometry, combining cutting teeth with specially designed chip-removal teeth for super-fast cutting action in metal and wood.

great holesaw kit The Bosch holesaw kit has performed flawlessly for me so far, it is fast and easy to change holesaw sizes and the arbor holds them snugly with no play in the bit making it much more precise than the type I have used in the past. Highly recomend this to anyone looking for a nice holesaw kit.
Fast and Easy The saws cut as fast as can be, and the speed change system is super fast making changes for differnt size holes less time consuming.
The best holesaw on the market Not only do these saws cut cleanly and agressively, they stay relatively cool. The snap-on/off feature puts this hole saw way above the rest. To clean out the wooden plug after cutting, simply remove the hole saw by pulling on the retaining collar, then snap the saw back on, automatically dislodging the plug. The best hole saw set I've owned or used, bar none.
Great idea, bad materials? I ordered this kit because it looked like a great new way to use hole saws. They are sharp and cut well but the big problem is the arbor, it's absolute junk. I don't know about you but when drilling holes with larger bits it's easy to have them hook and stop suddenly. With the old type of arbor, all you had to worry about was smashing your knuckles in tight quarters, or maybe a broken wrist or two :) The arbors for this set bend very easily when they hook. I've gone through three and the third was my last... more info
