新開工具製作所 Product Lineup

The "Slant Sink Cutter" uses a high-quality vice made of SKH55 (cobalt), achieving high durability for sink milling cutters. It enables high-precision chamfering of guide diameters. 【Features】 ■ Capable of chamfering guide diameters ■ Uses high-quality vice (SKH55) for excellent durability *For more details, please download the PDF or feel free to contact us.

• Reamer

The "Super Hard Stop Hole Reamer" is a bag hole reamer that employs our unique two-stage cutting method (rough blade and finishing blade) for excellent surface accuracy. It excels in straightness and can also accommodate stepped machining. We have various stocks available for bag holes, through holes, stepped holes, and TiCN coating. 【Features】 ■ Excellent surface accuracy ■ Excellent straightness ■ Overall short production for superior rigidity ■ Capable of stepped machining *For more details, please download the PDF or feel free to contact us.

• Reamer

The "Flat Hole Reamer" is a bag hole reamer that can discharge chips to the rear due to its right spiral design. It has a bottom blade, which provides excellent straightness, and all diameters except for the 45° tip are effective. Additionally, the double structure of the boring blade (which prevents wobbling) and the finishing blade allows for high dimensional accuracy and excellent surface roughness without worrying about reamer allowances. 【Features】 ■ Capable of processing completely blind holes ■ Surface treatment on SP-ALLOY powdered high-speed steel *For more details, please download the PDF or feel free to contact us.

• Reamer

The "Stop Hole Reamer" uniquely solves the unstable dimensional accuracy and difficult issues of right spiral blade processing in bag holes with its original structure. Thanks to the right spiral design, chips are discharged backward, preventing accumulation at the bottom of the hole. Additionally, with a bottom blade, facing is possible, making all diameters effective except for the tip IC. 【Features】 ■ The dual structure of the boring blade (FIX effect) and finishing blade allows for high dimensional accuracy and excellent surface roughness without worrying about reamer allowance. ■ The reamer material is made of high-quality high-speed steel (including cobalt) and is further treated with ion nitriding for superior durability. *For more details, please download the PDF or feel free to contact us.

• Reamer

The "New Stacking Reamer" is a reamer that achieves H7 accuracy and a surface roughness of 6S or higher. It uses cobalt (Co) as the material for the reamer, and additionally, due to an ion nitriding treatment, it has a high hardness layer of approximately Hv 1,150 to 1,200, which provides excellent performance on alloy steel and stainless steel. 【Features】 ■ Simplifies the processing of pilot holes ■ Excellent durability ■ The unique cutting structure of the stacking reamer and the FIX effect in the boring section control the phenomenon of reamer walking, ensuring high precision. *For more details, please download the PDF or feel free to contact us.
