Leading the industry in small-diameter gundrilling machines!
We know all about deep hole processing.
Making machines that utilize HI-TAK's processing know-how
- 1 Manufacture and sales of gundrilling machines and deep hole drilling machines
- 2 HI-TAK's expertise in deep hole drilling is utilized in the manufacturing of these machines.
- 3 Wide range of gundrilling machines for different workpiece shapes
- 4 Deep hole drilling by HITACHI gundrilling machines that are used in all fields!
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.
If you have a problem with deep hole drilling, this is the best choice.

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.
Simple Table Type Small Diameter Gun Drilling Machine
Suitable for workpieces with complex shapes
JDH-400-STS / JDH-400-ST
This small-diameter deep hole drilling machine realizes high-precision deep hole drilling of various shapes of workpieces flexibly and easily by placing a jig that matches the shape of the workpiece to be drilled on the table. As with other models, we have a lineup of machines for hole diameters from 1 to 6 and 4 to 10 mm.
Compact entry model for cylindrical workpiece machining
Relative Rotary Gun Drilling Machine
This is an entry-level model of the relative rotation type gundrilling machine for space saving. It realizes high precision and high quality deep hole drilling for hole diameters from 1.0 to 5.0 mm.
Flexible design and customization is possible according to customer requirements, processing diameter, workpiece material and material.
Our small-diameter gundrilling machines can drill holes for parts used in a variety of industries and equipment.
In some cases, we have been able to improve our customers' production processes by drilling holes in pre-formed workpieces using our know-how cultivated through years of contract processing. We have more than 60 customers in the medical field and have experience in machining for other applications. Our gundrilling machines are capable of machining deep holes in these parts.
