Information

Taps has straight flute thread taps, spiral flute thread taps, spiral point thread taps and thread forming taps. They are also classified into hand taps and machine taps according to the usage.

Hand taps are operated by tap wrenches. Machine taps are suggested to be used with the tap collet with overload protection, and hand use or electric drills use is easy to cause breakage to the tap.

Taps are prone to chipping or breaking due to speed overload or non-vertical tapping. Use the correct tapping tools, such as tapping wrench, tapping machine.

Spiral Flute Tap

Thread Tap

Spiral flute design, upward chip removal, right hand thread cutting, fast tapping with accuracy. It has high wear resistance, high cutting speed, high strength and hardness.

Cobalt High Speed Steel Tool

Cobalt high speed steel tool features high hardness (HRC65-66) and high red hardness, high wear resistance. Specially designed for drilling stainless steel.

Easy to Use

Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps.

Wide Applications

Suitable for processing blind holes, deep holes, and sticky materials, and tapping stainless steel, aluminum, die steel, bronze, hard plastics, etc..

Recommended feed rate: General steel: 6-15m/min; harder steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. Tips: The torque caused by too fast feed speed is too large, which can easily cause the tap to break.

Micro taps (such as M1-M3.5) are mainly used in clocks and watches, as well as for making holes in wood and soft metals with lower hardness.

Twist Drill Bit

Spiral Flute Bit

Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches.

Cobalt High Speed Steel Tool

Cobalt high speed steel tool features high hardness (HRC65-66) and high red hardness, high wear resistance. Specially designed for drilling stainless steel.

Wide Applications

For drilling stainless steel, aluminum, bronze, hard plastics, etc. Suitable lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy.

Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.

I used this drill and tap set to create four threaded holes in a copper plate for a custom computer CPU heatsink. The heatsink is mounted with 4x M3 x 0.5 screws. The drill bit and tap both worked well. The threads cut cleanly without any binding, and the tool held up well for four uses (as expected). I used a drill guide to ensure the tool was properly aligned before cutting, and CRC Cutting Oil lubricant, and everything worked great.ff

What can I say? It arrived the next day (just like Amazon stuff is supposed to)... It arrived in perfect condition. I used it the same day. The drill bit made 8 holes in brass easily and the tap created the threads in each hole. They all worked. I'm a happy customer.

I needed tap for stainless steel. I have learned that fluted taps are better for tapping in general and cobalt bits are better for stainless steel. Very useful to have since metric taps are very hard to purchase where I live.
