Maykestag HSS-Co5 FORTE deep-hole twist drill 13mm x 480mm DIN 1869

Product information

Maykestag HSS-Co5 FORTE deep-hole twist drill 13mm x 480mm DIN 1869 Professional extra-long 13mm twist drill manufactured from HSS-Co5 to DIN 1869, featuring FORTE geometry, a reinforced core, 130° point angle and a 330mm flute length for drilling extremely deep holes up to 10 x D. The Maykestag D1869 Type FORTE is a specialised extra-long twist drill designed for drilling extremely deep holes where chip evacuation and cooling can be challenging. Manufactured from HSS-Co5 and profile-ground for precision cutting, the drill features a substantially reinforced core, increased side rake and a 130° point angle. Its 13mm diameter, 330mm spiral length and 480mm overall length provide the extended reach required for deep-hole drilling applications. The FORTE geometry is designed to provide improved stability and chip flow compared with a conventional twist drill, particularly in deep drilling operations. What is a deep-hole twist drill? A deep-hole twist drill is a specialised drill designed to produce holes substantially deeper than those normally possible with standard-length drills. Extra-long geometry provides the additional reach required for deep holes, while specialised flute and core geometry helps maintain stability and assist with chip evacuation. The Maykestag D1869 FORTE is designed for drilling depths of up to 10 times the drill diameter under appropriate machining conditions. Product highlights • HSS-Co5 construction: Cobalt-alloyed high-speed steel provides increased heat resistance and durability for demanding drilling applications. • 13mm drilling diameter: Provides a substantial drilling diameter for deep-hole applications in suitable metallic materials. • 480mm overall length: Extra-long construction provides the extended reach required for deep drilling applications. • 330mm spiral length: Long flute geometry provides the cutting depth required for exceptionally deep holes. • FORTE geometry: Specialised geometry developed for deep-hole drilling where chip evacuation and cooling can be difficult. • Reinforced core: A substantially stronger core improves tool stability during deep drilling operations. • 130° point angle: Supports stable entry and cutting performance in demanding drilling applications. • 38–40° spiral angle: Supports efficient chip evacuation along the extended flute length. • Profile-ground cutting geometry: Precision-ground cutting edges provide consistent drilling performance. • Cylindrical shank: Conventional cylindrical shank for use with suitable drill chucks and toolholding systems. • DIN 1869: Manufactured according to the DIN 1869 standard for extra-long twist drills. Why choose Maykestag? Maykestag is an Austrian cutting-tool manufacturer focused on precision-manufactured tools for professional machining. Consistent control of cutting geometry, tool material and dimensional tolerances is important for achieving reliable machining results and tool life. The D1869 FORTE series is designed specifically for drilling applications where standard drill lengths are insufficient. Its reinforced construction and specialised flute geometry make it a practical solution for demanding deep-hole drilling applications where stability, chip evacuation and adequate cooling are critical.
