AUTOTOOLHOME Titanium Drill Tap Bit Set for Thread Drilling and Tapping

AUTOTOOLHOME Titanium Combination Drill Tap Bits Set are made of high-speed steel 4341, ensuring sharpness, fast execution, and retained strength and efficiency. The surface is treated with a titanium alloy, greatly improving the drill's cutting performance, making it more wear-resistant, and prolonging its service life.

The 13-piece drill tap kit includes both SAE and metric sizes, suitable for most commonly used screw tapping. The SAE sizes are 6-32NC, 8-32NC, 10-24NC, 10-32NC, 12-24NC, and 1/4-20NC, while the metric sizes are M3 x 0.5, M4 x 0.7, M5 x 0.8, M6 x 1.0, M8 x 1.25, and M10 x 1.5. The kit comes with a storage case and a quick-change adapter for easy bit switching.

The drill tap bits allow for a one-step process of drilling, tapping, deburring, and countersinking, enabling the user to complete jobs on a variety of materials, including copper, brass, aluminum, sheet metal, mild steel, and plastic (up to 5mm thick), saving processing steps and time, and improving work efficiency.

Each drill tap bit is engraved with the right size, making it convenient for the user to choose the appropriate size. The strong hex shank ensures a secure connection to the drill, and the tapered end helps prevent excessive knocks. The back taper exceeds the tap, preventing over-drilling and damage to the thread.

The included swivel storage case props up the tap drill bits and securely holds them in place until ready for use. The case folds up neatly, making it convenient to travel with on different job sites and locations.

The 1/4-inch hex shank quick-change adapter allows for easy switching between different bit sizes, saving time and enhancing efficiency. The 2-inch quick-release bit holder features a magnetic locking design, ensuring the bits stay in place during use.
