Triangular shaped reamer pins are specially shaped pins specialized for high-precision hole drilling in brittle materials. They are especially active in the fields of stationery sundries, medical equipment, watches, eyewear, and jewelry in drilling holes in brittle materials that are difficult to process with ordinary tools. Sanwa Creation Co., Ltd. provides equilateral triangular shaped cemented carbide reamers and achieves high coaxial accuracy through one-chuck machining.

Features of Triangle Shaped Reamer Pin
The triangle shaped reamer pin is a special tool that enables hole drilling of brittle materials, which is difficult with ordinary round tools. The blade shape is an equilateral triangle, and the one-chuck process maintains high coaxial accuracy, resulting in almost no axial misalignment with the shank. This makes it ideal for use in the jewelry and precision instrument fields, where high-precision hole drilling is required.

High-precision machining by equilateral triangle blade shape
The blade of the reamer pin is an equilateral triangle and can be used for sizes from φ1.0 to φ1.0 as a circumscribed circle. The sharp triangular apex prevents burrs even in brittle materials, resulting in a clean finish. 2.

2. high coaxial accuracy by one-chuck processing
Sanwa Creation minimizes blurring during forming by using the one-chuck processing technology. This prevents axial misalignment of the blade and shank and achieves extremely stable machining accuracy. 3.

3. High Durability with Cemented Carbide
Cemented carbide is used for the blade material to achieve both hardness and wear resistance. Even when machining brittle materials with high precision, the blade wears little and maintains a long service life. Reamer pins made of zirconia ceramics and SKH (high speed steel) can also be used, allowing you to select the material that best suits your application.

Applications and Usage Scenes
1. High-precision hole drilling of jewelry
In jewelry processing, high-precision holes need to be drilled in precious metals and special materials. Triangular shaped reamer pins are used in jewelry production, which requires less burrs and delicate processing. 2.

2. Precision Parts Machining for Medical Equipment
Metal parts used in medical equipment require durability and high precision. Reamer pins made of cemented carbide are particularly suitable for highly brittle ceramic parts.

3. Parts Machining for Watches and Glasses
In machining holes for watch parts and eyeglass frames, fine and accurate finishing is essential. High coaxial accuracy by one-chuck machining supports precision parts production.
