The "HT 800 WP" is a replaceable tip drill developed by a German global manufacturer with over 125 years of history, capable of processing holes up to Φ40.
The 'HT 800 WP' accommodates hole machining up to a maximum diameter of Φ40 with standard products, offering a variety of inserts and holders that support machining depths from 1xD to 10xD, tailored to the workpiece material. The inserts feature a special finish on the cutting edge, providing excellent wear resistance. The holders are designed with a size increment of 0.5mm, ensuring a robust design with high rigidity. The unique groove shape allows for optimal chip evacuation even in deep hole machining. By incorporating a coolant duct on the groove heel side, effective coolant supply to the cutting edge is made possible. *For more details, please refer to the cutting conditions table in the product catalog or feel free to contact us.

Company information
In 1898, the founder Gottlieb Gühring began the production of cutting tools in Germany based on the belief that "the highest quality conquers the world." In the early days, the number of products was small, and the catalog consisted of only a few pages, but now we have a standard product lineup that exceeds 4,500 types and 100,000 items. "We will not allow others to catch up with us in terms of product quantity and precision" – this belief will continue to be the foundation of our company as we strive to improve. "From standard products to special items, from spindles to cutting edges" – we sincerely wish to be a strong partner for our customers by not only developing and manufacturing cutting tools but also earnestly addressing any challenges related to cutting technology.
