The "Wood Material Groove Processing Blade" is a tool used for processing the grooves of the thresholds in Japanese-style rooms. Due to the fibrous nature of wood, a significant amount of burrs can occur if the bottom and side surfaces are not processed simultaneously, which has been a challenge. To process these three surfaces at the same time, the design combines a bottom blade with side blades on both sides, ensuring a beautiful finish across the entire surface. This product is also used for groove processing of foam resin. 【Features】 ■ Material: SS400 (cast iron), SKH51 ■ Designed to combine the bottom blade with side blades for simultaneous processing of three surfaces ■ Designed to achieve a beautiful finish across the entire surface ■ Also used for groove processing of foam resin *For more details, please refer to the PDF document or feel free to contact us.

The "Square Hole Processing Tool" is a tool designed to create square holes in wood. It can be attached to a dedicated machine, similar to a drill press, and can make a square hole in one pass. Due to its special design, which consists of an outer chisel and an inner drill, high axial precision is required. It undergoes special heat treatment to enhance resistance to breakage, and is designed with a unique spiral shape to improve chip removal. 【Features】 ■ Material: SKD, SKH51 ■ Can be attached to a dedicated machine to create square holes in one pass ■ Enhanced resistance to breakage through special heat treatment ■ Designed with a unique spiral shape to improve chip removal *For more details, please refer to the PDF document or feel free to contact us.

The "Long Drill for Wood Processing" is a drill used for processing long holes when joining wood. Due to the fibrous nature of wood, when it comes to long holes, the fibers can pull, making straightness during processing a challenge. In this development, we enhanced the rigidity of the body by applying a special heat treatment, and improved the fiber shearing force at the cutting edge to increase straightness during processing. 【Features】 ■ Material: SS400, SKH51 ■ Increased rigidity of the body through special heat treatment ■ Enhanced straightness during processing by improving the fiber shearing force at the cutting edge *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to our "End Mills for Plywood Processing." Wood-based plywood is a material made by laminating thinly sliced veneer sheets with adhesive, which makes the adhesive parts very hard and leads to rapid wear with standard carbide tools. In this development, we aim to extend tool life by brazing artificial diamond tips to the cutting edge and have designed it to minimize burrs by adjusting the cutting angle. There are also similar products available for resin processing. 【Features】 ■ Material: Artificial Diamond ■ Extended tool life by brazing artificial diamond tips to the cutting edge ■ Designed to minimize burrs by adjusting the cutting angle ■ Similar products are available for resin processing *For more details, please refer to the PDF document or feel free to contact us.

The "Wood Crushing Blades for Pulp and Paper" are blades used to crush and chip wood to produce raw materials for paper pulp. When crushing materials such as thinned wood and construction waste, issues arise when small stones and nails mix in, causing the blade edges to chip. To minimize damage to the blade edges even when encountering such hard materials, we have developed our own high-impact-resistant raw materials and heat treatment conditions. Similar blades include those used for crushing PET bottles and paper products. 【Features】 ■ Minimizes damage to the blade edges even when encountering hard materials ■ Developed our own high-impact-resistant raw materials and heat treatment conditions ■ Similar blades are used for crushing PET bottles and paper products *For more details, please refer to the PDF document or feel free to contact us.

This is a model of the tool "square chisel" used for making mortises (square holes) in wood, designed for precut factories. We have updated the know-how cultivated through the Kobayashi-style square chisel used in the furniture and fittings sector to meet the demands for higher durability and stability required in precut factories. By continuously reflecting user feedback and making improvements, we have achieved a high balance of performance in sharpness, durability, and stability. It is less likely to experience issues such as drill tip breakage, contributing to stable line operation. Additionally, by operating within a fixed processing volume cycle of approximately 2000-2500 tsubo/month, it can be used long-term, which also helps reduce tool costs.
