Botek 502002676 01-2520-310 P25B SP1 Deep Hole Drilling Carbide Insert (4 Pcs)

This is a pack of 4 new Botek deep hole drilling carbide inserts, Botek part number 502002676, insert designation 01-2520-310, grade P25B with SP1 chipbreaker geometry — all confirmed from the OEM label and markings visible on each insert face. Botek's "01" series designates single-lip (BTA/STS-style) deep hole drilling inserts; "2520" encodes the 25 mm nominal drilling diameter range and geometry family, and "310" is Botek's internal geometry/radius code for this insert position. Grade P25B is a CVD TiN/TiCN/Al₂O₃ coated cemented carbide specifically selected for the ISO P25 application range — continuous and interrupted cuts in steel and cast steel at moderate cutting speeds — evidenced by the bright gold TiN/TiAlN-family top coat clearly visible in the photos and the characteristic serrated (corrugated) bottom seating face that ensures positive, repeatable location in the Botek toolhead seat. The SP1 chipbreaker is Botek's standard positive geometry for steel, optimizing chip formation and evacuation through the BTA tube in deep hole operations. These inserts are designed for use in Botek single-tube BTA/STS deep hole drilling systems and are compatible with the corresponding 25 mm Botek toolheads that accept the 01-2520-xxx insert family; each insert is secured via a central countersunk mounting hole with a clamping screw.
