Manufacture and sales of gundrilling machines and deep hole drilling machines 

Our gundrilling machines and deep hole drilling machines meet a wide variety of needs in the medical, aerospace, automotive, and semiconductor fields. In particular, our gundrills (tools) can achieve deep hole drilling with high concentricity (concentricity) for workpieces with extremely small diameters (φ0.5 gundrills) and L/D (depth to hole diameter) exceeding 200, which have been difficult to achieve with conventional small-diameter gundrilling machines and small-diameter deep hole drilling machines. In addition to the models sold overseas, we also have a wide range of conventional models sold in Japan, so we can offer the most suitable machine for our customers.

HI-TAK's expertise in deep hole drilling is utilized in the manufacturing of these machines.

Gundrilling machines / Tip boxes for small diameter deep hole drilling

Wide range of gundrilling machines for different workpiece shapes

Relative rotation type small diameter gundrilling machine

JDH-600-RF / JDH-600-R

This small-diameter deep hole drilling machine is a high-precision model (patented internationally) developed for advanced fields such as the medical, aerospace and semiconductor fields. It is designed specifically for hole diameters of φ0.8 (0.5) to φ6.0, which are in high demand for medical devices, and enables high-precision, high-quality deep hole drilling of workpieces with extremely small diameters and L/D = 200 or more, which have been difficult to achieve with conventional small-diameter deep hole drilling machines. High precision and high quality deep hole drilling is realized. The models with large hole diameters are specialized for large diameters from φ4 to φ13.

Table type small diameter gundrilling machine

High-precision, multi-hole machining of square and irregular-shaped workpieces

JDH-600-TF / JDH-600-T

This small-diameter deep hole drilling machine is a table-type gundrilling machine developed to drill holes at any position in workpieces of various shapes. This high-precision model (patented internationally) is designed specifically for hole diameters of 0.8 (0.5) to 6.0, which are difficult to drill with a gun drill. By installing FANUC's CNC system, it is also possible to create drilling programs using the world standard G-code.
