2 Lenox 4-5/16" (109mm) wood hole cutters - part #25469-69HC. Once you switch to this single tooth design you will never go back to the saw tooth style of hole saw. These are faster, last longer and hog through wood like nothing else. A nice design from one of the top names in wood cutting tools. This 4-5/16" diameter hole cutter is intended for use with 4" duct pipe and bendable duct pipe. Features include:
Cuts wet, frozen, and pressure treated woods without binding - also great for hardwoods
4-5/16" diameter
2" drilling depth
Fits standard arbor (not included)
Cuts 3 times faster than conventional hole saws
Less binding and less user fatique than with self-feed bits
Long lasting - high speed steel tooth can cut over 300 holes before re-sharpening
Cuts fast - 3/8" stubby spade bit helps remove material quickly
Can be used to cut holes at an angle
Wide side slot and generous internal clearance make for fast plug ejection with a screwdriver or similar tool
Please note that single tooth saws like this are for rough-in work. If you need an exact hole size or are boring into a delicate material, you should use a multi-tooth design with fine teeth on it
