Fuji Seiko Holders & C-Max

Fuji Seiko Holders

Accuromm offers custom design and small lot production capabilities, using Pull System manufacturing at our plant in Lexington, Kentucky. Combining stateside resources with the capabilities of our parent company Fuji Seiko Ltd. of Japan, Accuromm delivers total tooling for higher precision machining. Accuromm takes special pride in the company's ability to design and manufacture precision tools "from the hole up."

Show Accuromm engineers the holes your manufacturing process requires. They'll take your need to the drawing board for custom drill design. They will supervise the production of prototypes, and develop a proposal for the production of the right tools for your job. Ultimately, Accuromm backs up our proposal with outstanding service and timely delivery. Using precision brazing techniques, Accuromm can join different cutting edge materials to various tool body materials.

Indexable Inserts

Indexable Inserts

We offer many types of inserts for grooving and boring. We also have coated, carbide and PCD inserts.


Grooving Cutter

Grooving Cutter

  • Carbide cutting edges
  • Steel body
  • Cost effective
  • Can be designed with PCD
  • Assembled with arbor (Sold separately)

Angle Head Holder

Angle Head Holder

Angle Head Holders are designed when a machine table cannot rotate and special tilt clamp blocks are needed. The Angle Head Holder can drill any angle hole without a special clamp block. We can also combine with quick change stub holders.


Cartridge Holder

Cartridge Holder

Cartridge Holders are designed for rough and finish boring, chamfering and spot facing. After wear to the inserts and cartridges just replace insert and/or  cartridge according to wear. The body does not need replacement.


GB Tool (Guide Pad Boring Tool)

GB Tool (Guide Pad Boring Tool)

  • High Precision Machining:
    We assure stability and straightness of machining diameter. Self-supporting effect by guide pad can get ride of holder deflection caused by cutting resistance.
  • High Efficiency Machining:
    Compared with general boring, GB Tools enable improved surface roughness and higher feed rate because of specially designed insert and back taper adjustment system.
  • Easy Diameter and Back Taper Adjustments:
    Setting time of cutting diameter is greatly reduced because of the unique adjustment system for cutting edge compared with other manufacturers' T/A reamers.

Honing Head

Honing Head

Honing Heads are mainly for cylinder blocks and Connecting Rods. Cemented carbide is used on portions of the Honing Head's guide pads and shoe grooves. Honing Heads are excellent in wear resistance and gives an excellent surface finish.


Valve Finisher

Valve Finisher

Valve Finisher Holders are for finishing after setting valve seat guide. In order to ensure a common axis between the seat face and the guide hole, guide hole reaming and seat face boring are preformed on the axis of the same spindle,  thereby reducing process time and increasing performance.
