High-Quality Titanium-Coated High-Speed Steel
Bits made of high-speed steel (HSS) for durability and strength
Titanium coating improves cutting performance, reduces wear, and prolongs service life
1/4" hex shank ensures a strong, secure connection to drills
SAE Sizes for Versatility
The set includes 6 SAE sizes: 6-32NC, 8-32NC, 10-24NC, 10-32NC, 12-24NC, and 1/4-20NC. Back taper exceeds the tap to prevent over-drilling and protect the thread.
Wide Material Compatibility
Ideal for soft metals like aluminum, copper, zinc, and alloys, as well as low-carbon steel (HRC <28), ordinary steel plates, thin stainless steel, plastics, wood, and hard rubber. Not suitable for high hardness metals or thick stainless steel.
Easy to Use
Place the combination drill & tap bit perpendicular to the workpiece.
Drill the hole to desired depth.
Perform the thread tapping operation.
Countersink the hole if needed.
Clean debris to complete the operation.
Applications
Compatible with various power tools such as electric drills, impact drills, bench drills, electric screwdrivers, and other tap machines. Perfect for DIY projects, hobbyists, automotive work, and general metalworking.
