IRWIN Tools Drill And Tap Set for 1/4-Inch - 20 NC Tap and 13/64-Inch Drill Bit (80230)

High-speed steel drill bits ensure fast and precise drilling, producing a thread that is strong yet easy to tap. Hanson taps with a black oxide finish and a semi-porous matte surface are ideal for general purpose threading. The oxide surface-coating reduces the tendency for chips to weld to the tap, resulting in lower cutting temperatures and freer chip flow to increase tool life.

Drill and Tap Packs include a 1/4-inch - 20 Tap and a No. 7 Drill, providing a convenient solution for threading and drilling tasks. The high carbon steel Plug taps are manufactured to exacting tolerances, ensuring consistent performance.

Irwin tools are made of only the finest materials, including shock-resistant and heat-treated S2 steel, to provide maximum strength and hardness. These tools are ideal for maintenance and repair work, and are proudly manufactured in the United States.

The black oxide finish on the Hanson taps causes cutting oil to cling to the surface more effectively, carrying the oil into the cut and reducing the drive torque required, as well as lowering cutting temperatures. This innovative design feature enhances the overall performance and efficiency of the taps, contributing to their exceptional quality and durability.
