We have developed proprietary gun drilling machines equipped with a built-in servo spindle that enables high rotation precision to respond to various needs for deep hole drilling. Through many years of development of the gun drilling machine and the technology we have accumulated through contracted deep hole machining, we continue to provide deep hole machining to meet customer needs.

Our company’s service is processing material by original machines. We handle a variety of materials that can be bored with a deep hole by a particular device and also the content of the surface by the machining center.

  1. Support for various materials ~ We support difficult-to-cut materials, resins, woods, and other materials that cannot be handled by others
  2. High-precision deep hole machining on externally machined workpieces ~ Proposals for shortening and improving processes
  3. Support from single small lots such as prototypes and development products
  4. Support for mass production using machine automation
  5. Support for extremely difficult machining such as required concentricity Φ0.05
  6. Consistent support for inner and outer diameters (from material procurement to outer shape and deep hole processing)

Ultra-small diameter deep hole machining that changes the general idea of cutting !

Hole diameter φ1.0 mm x depth 400 mm, hole diameter φ0.5 mm x depth 105 mm. By combining the development of a gun drilling machine with deep holedrilling technology, we have achieved ultra-small diameter deep hole drilling in areas that was previously impossible with conventional gun drilling.

Over 1000 types of drill diameters and drill length

No.1 in the industry for gun drills owned

We constantly prepare the most suitable machines, tools, and jigs to provide high-precision, high-quality deep hole machining with short delivery times to meet customer needs.

HI-TAK deep hole machining is used in a variety of industries !

HI-TAK deep hole machining is used in the following types of industries. We can provide proposals for deep hole drill shapes to fit the unique needs of our customers (machinery sales, single unit contracted machining, and more).
