SANDVIK Coromant has released CoroCut MB (minibar), providing internal high-precision grooves in holes down to 10mm in diameter. It offers a range of insert widths from 0.7mm for circlip grooves and different insert sizes for shallow and deep grooves. Inserts for turning and threading are also available.

The CoroCut MB tools offer simple handling and easy and accurate indexing of the insert mounted with a screw from the front without removing the tool holder from the machine turret. The inserts are especially suitable for steel and stainless steel operations.

The boring bars are designed with internal cutting fluid supply directed at the cutting edge via two nozzles to ensure effective chip evacuation and sufficient cooling.

When using cylindrical bars with the EasyFix sleeves clamping system the click from the spring plunger provides precise clamping and the correct centre height of the tip. This leads to quicker setup times and reduces down time.
