• Grindstone

This product is a tool tip fixture designed to be attached to the tips of air tools and electric tools for use with chips. Using a tool equipped with a chip fixture at the tip, the "wrapping chip / S sheet chip" is used while being held in place. For more details about other products, please contact us. *For more information, please refer to the PDF materials or feel free to contact us.

• Other work tools

This product is a paper stick used for paper polishing. The "wood" material is soft and easily conforms to steel, allowing for quick polishing. On the other hand, "aluminum" is hard and does not conform easily to steel, resulting in longer polishing times, but it provides a very flat finish with minimal orange peel. There is also a set available that includes both "wood" and "aluminum." 【Features】 ■ Used for paper polishing ■ Using a spatula reduces polishing unevenness, fatigue, pain, and injuries ■ Each piece is handmade ■ Fits comfortably in the hand ■ Reduces fatigue *For more details, please refer to the PDF document or feel free to contact us.

• Other abrasives

The "Wrapping Stick & Wrapping Tip" is a product used for mirror polishing with diamond paste. It minimizes chipping and scratching. Selected wood suitable for mirror polishing provides excellent cutting and polishing performance. It can be used as is, or molded into small cube shapes for polishing flat surfaces to a mirror finish. 【Features】 ■ Used for mirror polishing with diamond paste ■ Minimizes chipping and scratching ■ Can be molded into small cubes for polishing flat surfaces ■ Achieves a flat finish through micro-vibrations from air tools *For more details, please refer to the PDF document or feel free to contact us.

• Other abrasives

This product is paper cut to dimensions of 6mm width and 12mm width. It is thin and flat against the grinding surface, which helps reduce the occurrence of orange peel, pinholes, and uneven texture. There is no need for cutting, which improves work efficiency, and the abrasive particles in the paper itself are uniform, providing excellent cutting power. Additionally, the uniform abrasive particles minimize clogging, gouging, and scratching. 【Features】 ■ Dimensions: 6mm width, 12mm width ■ No cutting required ■ Improved work efficiency ■ Uniform abrasive particles in the paper ■ Excellent cutting power *For more details, please refer to the PDF document or feel free to contact us.

• Other abrasives

This product is a diamond powder that has superior cutting ability compared to diamond paste and is highly effective for delicate mold polishing, which is prone to pinhole formation. Compared to the free abrasive method of diamond paste, the fixed abrasive method of this product can suppress the occurrence of pinholes. It is suitable not only for regular mold polishing but also for maintenance of small scratches and gas corrosion that occur during molding. 【Features】 ■ Superior cutting ability compared to diamond paste ■ Highly effective for delicate mold polishing, which is prone to pinhole formation ■ Can suppress the occurrence of pinholes *For more details, please refer to the PDF document or feel free to contact us.

• Other abrasives

This product is a diamond paste consisting of micro diamonds that form a solidly bonded mass structure. The artificial polycrystalline abrasives have extremely high mirror surface performance. Additionally, the diamond crystals feature a structure with countless fine edges, which allows for a high degree of mirror finish. It is suitable for use in high-quality molds that require high surface roughness and high mirror gloss. 【Features】 ■ Solidly bonded mass structure ■ Abrasives have extremely high mirror surface performance ■ Suitable for use in high-quality molds that require high surface roughness and high mirror gloss ■ Suitable for use with ESP materials (HRC 50 or higher) *For more details, please refer to the PDF document or feel free to contact us.

• Other abrasives

This product is a grinding wheel that can accommodate a wide range of specifications regardless of steel type, hardness, or type of processing. It has been developed to easily remove rough machining marks (cutting, electrical discharge machining, wire cutting). It demonstrates its effectiveness in surface polishing when the machining of steel materials is very rough, regardless of hardness or steel type. The grinding particles of the wheel are made of alumina, which has excellent breakage resistance. 【Features】 ■ Wide range of specifications possible regardless of steel type, hardness, or type of processing ■ Effective for surface polishing when machining is very rough ■ Uses alumina for the grinding particles, offering excellent breakage resistance ■ By using a water-soluble grinding wheel liquid, it helps reduce the occurrence of scratch marks *For more details, please refer to the PDF document or feel free to contact us.

• Grindstone

This product is a grinding wheel developed to facilitate the upgrading of grit size for pre-hardened steel materials with a hardness of HRC 40 or lower. To enable the grinding of relatively low-hardness steel materials, high-quality black silicon carbide with uniform particle size is used as the abrasive. It has excellent toughness and moderate cutting power. It is preferable to use this product on steel materials with a hardness of HRC 40 or lower. 【Features】 - Developed to facilitate grit size upgrading for pre-hardened steel materials with a hardness of HRC 40 or lower - Excellent toughness and moderate cutting power - Preferably used on steel materials with a hardness of HRC 40 or lower *For more details, please refer to the PDF document or feel free to contact us.

• Grindstone

This product is a grinding wheel that uses green silicon carbide as the abrasive. Due to its very high cutting power, it cannot be used on steel materials with a hardness of HRC40 or lower, as it will cause deep scratches. It is also characterized by being resistant to gouging and scratching. Additionally, by using water-soluble grinding wheel oil, the occurrence of gouging and scratching is further reduced. 【Features】 ■ The abrasive of the grinding wheel uses green silicon carbide ■ As a general abrasive, it has excellent cutting performance with hard abrasives ■ It is preferable to use it on steel materials with a hardness of HRC40 or higher ■ The use of water-soluble grinding wheel oil further reduces the occurrence of gouging and scratching *For more details, please refer to the PDF document or feel free to contact us.

At Hashimoto Industrial Co., Ltd., we perform mirror polishing on molds entrusted to us by our customers. The mirror finish can be accommodated up to #14000, and it is determined by considering the type of steel and customer requests. We believe that our polishing is fundamentally about preparing the base. By accurately increasing the grit in the grinding and paper processes, we can minimize issues such as "surface waviness," "orange peel," and "pinholes." 【Introduction to the Polishing Process】 ■ Grinding Process - Increase grit from #1000 to #1500 to #3000 - It is important to polish without causing shape deformation or leaving grit marks for base polishing. ■ Paper Process - Increase grit from #1500 to #2000 to #2500 to #3000 - This process has a very high occurrence rate of orange peel. ■ Diamond Process - Increase grit from #1800 to #3000 to #8000 to #14000 - This process has a very high occurrence rate of pinholes.
