Diamond Quality, Star Shining Shanghai - Dezhou DrillStar Cutting Tools Co., Ltd. invites you to explore new horizons in deep hole processing at the CCMT2024 exhibition!Leading the trend of deep hole machining technology, forging a high-end manufacturing national brand!Dear colleagues and partners i

Gun drilling is the oldest and most widely used method of deep hole drilling employed by industry today. The drill or “gun drill” is generally a one-piece assembly consisting of a hollow cylindrical drill driver. Also, it is brazed to a V-shaped crimped tube and finally assembled to a brazed-on soli

Deep hole drilling is the process frequently used for initial hole generation in large-scale industrial parts. When combined with Drillstar’s industry-leading bore finishing operations, deep hole drilling delivers exemplary levels of precision and efficiency to a wide variety of manufacturing applic

Today, Drillstar will introduce the detection of coolant holes and other characteristics of coolant holes. Firstly, you may notice that the drill bit backlash and cooling holes are not completely aligned. This is because we did not separate the drill bit from the coolant hole.

In the process of mechanical machining, the machining of holes has always been a key and difficult point in the entire machining engineering. Usually, drilling tools such as drills, drill chucks, reamers, honing rods, etc. are used. Floating fixtures are generally not mentioned in the industry, but
