Right Hand-hand Klein drilling tooling with a verified 40 mm diameter and 57.5 mm overall length for its intended drilling family.
Compatible automatic drilling machines using a 10 × 26 mm shank platform.
The Klein L143.400.R is a right-hand hinge boring bit engineered for industrial woodworking and panel-processing drilling. Verified Klein data establishes diameter 40 mm, overall length 57.5 mm, shank 10 × 26 mm, Z3+3 cutting geometry and H=0.5 mm Center Point.
The active cutting material is HW / Carbide-Tipped Tooling. This configuration is routed to Titan's carbide-material image because the verified cutting edge is HW/VHW/carbide and no PCD/DP/DIA cutting edge is specified.
Confirm the exact drill-bank, CNC, Trimatic, collet, or machine interface required for this SKU; verify rotation, seating, runout, drilling depth, workpiece support, extraction, spindle speed and feed rate before production.
