Greenlee DTAP12-24 Drill/Tap Bit
This Greenlee drill/tap bit combines drilling, tapping and countersinking in a single high-speed steel tool. It cuts a #12-24 UNC thread for machine screws in metal, plastic or wood. The bit fits standard drill chucks and is suited for maintenance, assembly and fabrication tasks where a separate tap would slow the job down.
12-24 UNC thread capacity
The bit handles #12-24 UNC threads and stops there; it cannot produce larger or finer pitches. It runs out when the workpiece thickness exceeds the flute length or when the material hardness demands a dedicated tapping setup with lubrication and rigid holding.

Questions about this item
Will the 12-24 UNC thread cut cleanly in the mild steel brackets I already have?
The bit is made from high-speed steel and drills, taps and countersinks in one pass, so it will produce a standard 12-24 UNC thread in mild steel without needing a separate tap.
How can I confirm the finished hole matches the 12-24 UNC specification after using the bit?
Run a 12-24 UNC bolt into the new hole; it should start easily and engage fully without binding, confirming the thread pitch and diameter are correct.
