The TD-1.300-0350N is a high-performance carbide drill bit featuring a Ø3.5 mm helix tip with two cutting edges designed for precision drilling. Its cylindrical shank allows for secure and stable attachment to various drilling machines. With a drilling depth capacity of 8 times the diameter (8xØ), this bit is engineered for versatility across a wide range of materials.
The coated S-TiN carbide tip enhances the durability and longevity of the drill bit, making it suitable for machining and drilling applications involving non-alloyed steels, alloyed steels, aluminum, various alloys, copper, brass, bronze, as well as composite materials like carbon fiber and CFRP. The specific coatings provide improved performance attributes such as reduced friction and increased resistance to wear.
An added advantage of the TD-1.300-0350N is the service option for re-sharpening and recoating the tips. This service helps maintain the efficiency and cutting performance of the drill bit, extending its lifecycle while delivering results comparable to new products. Additionally, upon request, customers can choose from various coating options to further tailor the drill bit to their specific machining needs.
