Exchangeable tip drill range extended

CoroDrill® 870 now offers pilot-hole geometry

Sandvik Coromant has extended its innovative CoroDrill® 870 range of exchangeable tip drills to include new pilot-hole geometry. In addition, a new Tailor Made offer is introduced for producing chamfered holes in a single operation. The Sandvik Coromant Tailor Made service gives customers the freedom to specify their own specific tool dimensions without having to pay the price of a special tool.

Better drilling

New -GP pilot-hole geometry for steel and cast iron workpieces results in an even more secure drilling process for deeper holes, while both -PM 4234 tips for steel and -KM 3234 for cast iron are also now available for smaller diameter holes.

The -GP geometry allows CoroDrill 870 users to achieve improved centring when making pilot holes prior to deploying drills up to 8xD in length. Featuring optimised point angle and diameter tolerance, the design enables a smooth and secure drill entry into the pilot hole and generates excellent performance and hole quality. Available in grade GC4234 for both steel (ISO P) and cast iron (ISO K) applications, -GP geometries are stocked as standard for common sizes.

As a range, CoroDrill 870 is now available in diameters from 10.00 to 26.65 mm, to meet H9-H10 tolerances.

Lower machine cost per hole or tool/insert cost per hole is achievable using CoroDrill 870 thanks to a host of benefits that include long tool life and high penetration rates. Furthermore, chip evacuation is facilitated by optimised drill flute shape, size and helix angle, while easy handling and secure tip changing is assured. In fact, it is even possible to change the tip while the tool is in the machine, thus minimising downtime.

Chamfer in one operation

To boost the efficiency of the CoroDrill 870 range even further, Sandvik Coromant is also introducing a Tailor Made 45° chamfer drill for producing chamfered holes in a single operation. Users have the option of one or two chamfer inserts.
