1.YESTOOLThe clamp type internal cooling systemdrill bitIt combines the characteristics of the traditional Fried Dough Twists drill and the common indexable bit, which not only has a good self centering effect, but also can easily and quickly replace the failed bit, thus reducing the auxiliary time. The cutting part of the machine clamp type internal cooling drill bit is completely ground from the whole cemented carbide, and its shape is basically the same as that of the traditional Fried Dough Twists drill. It is centered with the drill pipe by the central pin and fixed with the wedge screw. It can be easily and quickly replaced with the head cutting part like other indexable drill bits. The same specification of drill rod can be installed with five different diameters of heads, making the product more flexible in various applications. This product series can process aperture ranges from ф 8 to ф 50.4 or British ф 0.315 "to ф 2", with a spacing of 0.1 millimeters between each level. Drill rods are divided into three series based on hole depth: 3 × D, 5 × D, and 7 × D. There are two main types of handles: cylindrical straight handle and Mohs cone handle. The Mohs handle has a large specification of ф 25.4.

2. Welding edge drill bit is one of the products that YESTOOL is more concerned about by Chinese users. He expanded the size range of large-diameter solid carbide drill bits, which can process diameters ranging from ф 13.5 to ф 41.5, with two standard series of hole depths of 3 × D and 5 × D, and internal cooling water channel holes. The head is made of ultra-fine particle hard alloy material, with TiN or TiAlN coating on the surface. The shaft is made of high-quality tool steel after heat treatment, and the handle is a cylindrical body with chamfered edges, suitable for various clamping methods.

3. Solid hard alloy drill bits are YESTOOL standard conventional products, with diameters ranging from ф 3 to ф 20, hole depths of 3 × D, 5 × D, and 8D, available in two series with or without cooling water holes. The surface TIN or TIALN coating is a standard inventory item. YESTOOL can select different blanks, blade grinding treatments, and surface coatings for different processing object materials according to the specific requirements of customers' actual usage. We can also provide customers with special sizes such as step drills or drill bits with manufacturing tolerances. All series of solid carbide drill bits also offer drill bits with British aperture sizes.
