SAE Drill & Tap Bit Set 6-32NC to 1/4-20NC

The Cinrusge six-piece SAE combination drill and tap bit set covers thread sizes from 6-32NC through 1/4-20NC. Each bit is made from high-speed steel with a titanium nitride coating for improved cutting performance and wear resistance. The 3-in-1 design drills, taps and countersinks in a single pass, removing the need to change tools mid-task. A 1/4 inch hex shank provides a secure connection to compatible power tools.

DIY thread cutting in soft metals wood and plastic

This set suits hobbyists and tradespeople who need to create threaded holes in aluminium, copper, zinc alloys, low-carbon steel below HRC28, thin stainless steel, plastic, wood or hard rubber. It is not suitable for high-hardness metals or thicker stainless steel. Users who require metric thread sizes, larger diameters or dedicated taps for hardened materials should look at alternative tooling.

Fits electric hand drills impact drivers

The hex shank fits standard drill chucks and quick-change adapters on electric hand drills, impact drills, bench drills and electric screwdrivers. Because each bit completes drilling, tapping and countersinking in one operation, it frees up time and reduces the number of separate bits needed on the job. The back taper exceeds the tap to prevent over-drilling and protect the finished thread.

Questions about this item

Will these hex-shank bits fit my 1/4-inch chuck drill?

The 1/4-inch hex shank locks into any standard 1/4-inch hex chuck on electric hand drills, impact drivers or bench drills.

Can I use the 1/4-20NC tap on the low-carbon steel plate I already have?

Yes, the set is rated for low-carbon steel below HRC 28, so a typical mild-steel plate will thread cleanly with the 1/4-20NC bit.

How do I know the 3-in-1 bit drilled, tapped and countersank correctly in one pass?

The back taper exceeds the tap depth, preventing over-drilling; a clean thread and flush countersink on the workpiece confirm proper operation.
