Combination Drill & Taps Bit Set, SAE Sizes 6-32nc to 1/4-20nc, Anti-rust Black Coating

The Combination Drill & Taps Bit Set is a versatile tool that can be used to tap various threads, accommodating different needs. It includes 6 SAE sizes: 6-32NC, 8-32NC, 10-24NC, 10-32NC, 12-24NC, and ¼-20NC. These bits are designed to drill, tap, deburr, and counter holes on wood, copper, brass, aluminum, soft metal sheets, and plastic. Equipped with a 1/4-inch hex quick-change shank, they can be used with electric hand drills, impact drills, bench drills, electric screwdrivers, and other tap machines.

These drill-tap bits are not suitable for drilling blind holes, as they may break the bit if the workpiece is thicker than their working range. With a bench drill, they can drill a maximum thickness of 3/16" (5mm), while with a hand drill, the maximum thickness is 1/8" (3mm).

The advanced black oxide coating technology provides rust prevention and a classic appearance. To ensure the longevity of the bits, it is essential to follow some techniques:

1. Thin drill bits are more prone to breaking, so it is crucial to drill carefully and ensure the bit is perfectly straight.
2. Before starting the drilling process, use some cutting oil. This will facilitate easier drilling, prevent the drill bit from snapping off, and keep the drill from overheating and becoming damaged.
3. Avoid applying excessive pressure, as it can damage the drill bit.
4. Start drilling the surface slowly and gradually increase the speed. Drilling at high speed from the beginning can cause the bit to slip off.

The Combination Drill & Taps Bit Set allows users to combine drilling and tapping in a single operation, saving time and effort when creating threads for hinges or other projects. No more using a separate drill and tap tool.

The set offers high versatility, with 6 drill-tap bits in SAE sizes that can be used with a variety of power tools, including electric hand drills, impact drills, bench drills, electric screwdrivers, and other tap machines.

These drill-tap bits are handy tools for those who fabricate frequently. They can be used on aluminum, plastic, wood, and other thin, soft metal panels. When using the bits, ensure they are perfectly straight, take your time, go slow, and use lubrication to prevent breaking the bit in the hole.

For ease of use, each tap drill is engraved with its size, making it convenient to select the appropriate size at a glance. The tapered end on the hex shank can prevent excessive knocks, and the back taper exceeds the tap to prevent over-drilling and damage to the thread.

The Drill Tap Bits set comes with a portable storage case for convenient use and storage. If any issues arise during use, the manufacturer offers satisfactory customer service.
