Dapra's new SBD series inserts help operators finish their back draft jobs faster, with greater accuracy – and fewer insert changes – for maximum performance in long-reach, low-pressure finish cutting.

SBD inserts are the latest addition to Dapra's EDGE² SBN finishing system and are interchangeable with SBN series twin-edge ballnose inserts. A positive-rake cutting wiper allows for larger stepdowns and faster feed rates than traditional back draft-style inserts. Ultrarobust carbide insert thickness provides optimal rigidity and heat control for superior tool life, and strong insert seating accepts cutting forces with minimal deflection to eliminate insert movement.

These inserts are available in 0.500" to 1.000" diameters. Dapra offers a choice of two new premium coatings for SBD: TS (AlTiN-based) for general-purpose machining in most steels, irons and 400 series stainless steel; and HM (AlCrN-based) for hardened steels, high-temperature alloys and tough 300 series and PH stainless steels.
