Try our Standard Products set to

 Regular Processing Hole Accuracy of H7.

Takezawa's Reamers are able to meet even higher qualifications by

 providing customized items upon your request.

 - Easy to Handle -                                                                                 

Takezawa's Reamers perform the job of bore finishing

in just one round trip, the method which we call

"Single-Pass Honing."

Just mount the tool

on your drilling machines or on your machining centers

to obtain smooth bore.

It's as easy as using your ordinary tools, and still gives you finest quality.

For higer accuracy, single-pass processing may be performed multiple times

by using reamers with different grain sizes.

 -  Mechanism to Utilize the Tool till its Limit. -                                    Diameters of our reamers can be fine-tuned simply by

turninig the adjustment screws.

When grains worn down causing diameter decrease,

it can be compensated for by just turning the screws;

freshening up the grains and thus enabling you to utilize the reamers

to their maximum limits.

(Applicable only to Adjustable Types.)

 -  Amazingly Long Lives!  -                                                                     The highly valued extreme hardness of our diamond

and borazon CBN tools have four times the friction resistance

compared to regular grinding stones.

Due to the unique expansion function,

the tool life of Takezawa-Seiki reamers is up to 400%

that of ordinary reamers. 

 - Other Advantages -                                                       

- You will see improvements in ROUNDNESS and SURFACE ROUGHNESS.

- Longer tool lives will save expenses. 

- By adopting the SINGLE-PASS HONING method,

   you will save machining time drastically.

- Takezawa uses only Japanese-Made Diamond and borazon CBN powders.

- Our tools are made by the most advanced NC machines,

   hand-finished by our skilled workers, and

   inspected by the most precise instruments.

- Able to choose from DIAMOND or borazon CBN grains

   depending upon the material.
