Sandvik standardises specials for deep hole machining
1 min read
Sandvik Coromant's increased deep hole machining solutions make previously special-only drilling ranges available as standard. The company has also introduced a geometry for counterboring inserts along with an insert grade for skiving operations.
The CoroDrill 800 and 801 deep hole drilling systems are now available as standard on short delivery times. While the former is offered in specific 25 to 65 mm diameters and the latter in 65 to 165.1 mm, together they form a complete standard range across applications that include oil exploration, aerospace and primary metals.
Collets and sealing sleeves for generic STS applications will now also be stocked as standard. The programme consists of 21 sizes covering tube range 94 to 13E (drill size 15.6 to 65 mm).
Similarly, the CoroDrill 818 counterboring system is now stocked in specific sizes 40 to 301.75 mm. For use on STS machines, CoroDrill 818 is supported by insert geometries and grades for all materials. The A geometry, an addition to the TXN insert family, provides high process security when counterboring extra long-chipping materials such as Inconel and duplex stainless steels.
TXN inserts feature dedicated chip breakers for superior chip control and an iLock tip seat interface for secure location. Furthermore, the inserts are suitable for both push and pull counterboring operations. Metric insert sizes 16, 25 and 40 are available in four different grades.
Insert grade GC1525 has been introduced for skiving operations in high alloy steels and duplex stainless steels. Aimed at manufacturers in the hydraulic tube and oil and gas sectors, GC1525 is designed to enhance both surface finish and tool life, while reducing cost per component. It is available in metric insert sizes 6, 7 and 11 for a diameter range of 38 to 305.6 mm.
