These premium threaded drill bits are machine-shop grade tooling used in a variety of applications where precision and productivity are required.
The problem with most other bits is that they are soldered together and can become loose in the holder and even separate as the temperature of the bit and material being drilled increases. Moreover, typical bits on the market are limited by the hardness of the steel they can cut and the accuracy that they fail to deliver.
ProMAXX PSSC drill bits have a proprietary fit into the holder, eliminating the inexpensive soldering that can delaminate and cause them to separate. Because these bits are turned out of cobalt steel, they are capable of cutting into extreme hard materials including Rc. 55, which is TWICE the capability of any other drill bit.
We decided to manufacture the most commonly needed sizes and lengths but went one step further. We included an adapter so that you can run the threaded bits in any common electric or air-powered drill.
Lastly, we know that a freshly drilled hole can create a bur upon entry of the bit. That burr can be hazardous and restrict subsequent seating of a screw or pop-rivet.
We took care of that problem by including a threaded chamfer bit to eliminate the burr and clean up the hole in applications including preparation for a tap.
The PowerDrive Accessory Pack includes seven powerful bits in multiple sizes and lengths and a countersink. The Accessory Kit Plus comes with an adapter that allows for the threaded-shank tooling to be used in a traditional drill chuck. The PowerDrive also offers precise tolerances, giving more accurate drilling than a three-jaw configured handheld drill and chuck.
