4H Grade Forming Taps Metric Thread Lower Hole Diameter

High Quality Drill Sizes Forming Taps Metric Thread Lower Hole Diameter

Product standards include: ISO standard, Japanese child S standard, American standard, GB standard.

Among them, the life of hard alloy extrusion taps is more than 5 times that of imported high-speed steel extrusion taps.

More than twice the efficiency

Advantages of extruded taps

Compared with traditional cutting taps, extrusion taps have many advantages, mainly in

1. No chips are generated during processing, especially suitable for machine tools with a high degree of automation

2.High production efficiency, work efficiency can be increased by more than 1 times;

3. The tool wear is small, which effectively extends the service life of the tool and shortens the time used to replace the tool;

4.High processing accuracy, up to 4H grade

5.The thread strength of the workpiece is good, the crystal fiber of the workpiece is not cut, and it is kept in a continuous state, plus the extrusion process

The cold work hardening effect in the middle, so the strength is much higher than the cutting tap;

6.High finish, due to the squeezing effect of the cutter on the tooth shape of the workpiece, the surface roughness is improved, and the Ra value

Up to 0.4

7. More suitable for processing deep hole thread, through hole thread and blind hole thread
