This hand countersink cuts a countersink or eases sharp hole edges by hand, which is often quicker than switching to a power tool to countersink only a few screws.
50K6201 - Hand Countersink
In most instances, when you need to countersink a few screws, it is easier to use a hand tool than a power tool.
This eight-fluted hand countersink with an 82° included angle makes quick work of countersinking or easing hole edges and it is perfectly suited to deburring holes in brass and mild steel.
The large number of flutes means the handle need only be rotated 45° when countersinking. Ideal for installing shelf-support sleeves, whose rounded shoulders must be accommodated for flush seating.
With an octagonal hardwood handle and 5/8" diameter head, it is 5 1/2" long overall.
A simple yet useful tool.
