Using a twist drill to change into a taper hole reamer

In production, there are often taper holes with different tapers. There is no suitable taper hole reamer, especially in single-piece or small-batch production, in order to reduce the special reamers used for processing taper holes and to reduce the number of processes used. The process and time can be changed to a taper hole reamer using ordinary twist drills. After many uses, the effect is very good. Restructuring method: The standard twist drill is ground on the grinding machine to the required cone size of the reamer, and then tool grinding (or hand grinding) is used to grind the back corner and leave a reasonable edge band to use. When using, drill the bottom hole with a bit smaller than the diameter of the small end of the taper hole, and then use a taper hole reamer to ream. During the reaming process, the corresponding cutting fluid can be selected according to different workpiece materials to prolong the tool life and improve the reaming quality.

Tanto

The Tanto was primarily used as a weapon by samurais and was often carried as a secondary weapon alongside a longer sword, such as a katana. It was designed for close-quarters combat and was used for stabbing and slashing.

The blade of the Tanto is usually made from high-quality steel and is known for its sharpness and durability. The handle is traditionally made from wood and is wrapped with a cord for a secure grip. Some Tanto may also feature decorative elements such as ornate carvings or inlays.

In addition to its use as a weapon, the Tanto also had ceremonial and symbolic significance in Japanese culture. It was often given as a gift or used in rituals and ceremonies.

Today, the Japanest Tanto continues to be appreciated for its craftsmanship and historical significance. It is often collected as a piece of art or used in martial arts training.
