Solid carbide taps suitable for tapping Cast Iron, Aluminum alloy, Titanium alloy, Steel(HRC45~65).

CPM taps is suitable for tappingCast Iron, Aluminum alloy, Steel (≤HRC45), Nickel based alloy, Titanium alloy and Stainless steel.

Carbide taps are quite tough and have high resistance feature, are suitable for machining the products of large lot and high efficient and the product of continuous machining. According to the application, there are several kinds of taps: Machine and hand taps, spiral flute taps, spiral pointed taps, thread forming taps, and Pipe taps and thread milling cutter.

1. Machine and hand taps

The very standard tap, mostly are the Straight flute tap. Typically, tap is constituted by a working portion and a shank portion. The working portion is divided into a cutting portion and a calibration section, the cutting portion having a cutting bevel, responsible for cutting work. The calibration section is used to calibrate the size and the shape of the thread.

2. Spiral flute taps:

The spiral flutes have high cutting performance, eject chips smoothly, leave no chips in the hole bottom, suitable for tapping sticky materials. The chip-hold groove of Spiral fluted tap is spiral. According to the application, they are divided into two kinds: Left spiral flute tap and right spiral flute tap. Left Spiral flute tap tapping the chip to the bottom, suitable for through hole. Right spiral flute tap tapping scraps discharge upwards, so its suitable for blind holes.

3. Spiral pointed taps:

Suitable for through-hole and deep thread, have high strength, long life, fast cutting, dimensional stability, explicit tooth pattern (especially fine tooth). It opens chute in the side of the cutting edge of the straight groove, to form an angle, the chips are discharged forward when threading, suitable for through-hole processing. Relatively large core size design, good strength, can withstand greater cutting force. It is suitable for processing of non-ferrous metals and stainless steel and black metallic.

4. Thread forming taps:

These taps make threads by deforming the materials and do not produce chips. They are suitable for the blind holes of rather soft material or non-ferrous metals. The internally extruded and threaded metal has fibers which are continuous and has high tensile strength and shear strength, and has good surface roughness too.

5. Pipe taps

The pipe taps are used for mechanical joints purpose which is cutting the pipe fitting threads. There are two kinds of types, taps for parallel threads and taps for taper threads. The parallel threads are used for mechanical joints. The taper threads are used for pressure type joints such as water pipes and gas pipes.

6. Thread Milling cutter:

The thread milling cutter is a new developed processing tool in recent years. Its the combination of the milling cutter and the tap, using milling for machining the thread, so we call it the thread milling cutter. It is suitable for processing the large aperture work piece, avoid the disadvantage of high cost for large size Taps.

The carbide rods we are using for machining the taps are imported from Konrad (Germany), the powder HSS (CPM) rods we are using are from BOHLER (Germany) and OKOSHI NACHi (Japan).

We can design according to customer's requirements.
