Dapra Corp.’s (Bloomfield, CT) SBD series inserts help operators finish back draft jobs faster, with greater accuracy, and fewer insert changes, for maximum performance in long-reach, low-pressure finish cutting.

The latest addition to the company’s EDGE² spherical ball nose (SBN) finishing system, the SBD inserts are interchangeable with SBN series twin-edge ball nose inserts. A positive-rake cutting wiper allows 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. Strong insert seating accepts cutting forces with minimal deflection to eliminate insert movement.

The inserts are 0.5 in to 1 in in diameter and available with two premium coatings: TS (AlTiN-based) for general-purpose machining of 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.
