Sandvik Coromant 6035745 Replaceable-tip Drill 19mm

Product Description

The SANDVIK COROMANT 6035745 is a replaceable-tip drill body from the CoroDrill 870 series, designed for precision hole-making in metal-cutting applications. The tool accepts 870-1990-19-PM insert tips and supports a drill diameter range of 19 to 19.99 mm (0.7480 to 0.7870 inches). Maximum drill depth reaches 63.01 mm (2.4807 inches), placing it in the 3xD depth-to-diameter category. Overall length is 142 mm (5.5906 inches). The steel body features through-coolant capability, delivering cutting fluid directly to the tip for improved chip evacuation and tool life. This drill body is installed and serviced by machinists and CNC tooling technicians in production and job-shop environments.

The 6035745 fits the Toolholder Style 870 LX-3 configuration and is suited for use in CNC machining centers and turning centers where consistent hole quality and repeatable tip indexing are required. The replaceable-tip design reduces downtime compared to solid-carbide drills by allowing tip swaps without removing the body from the spindle. Compatible insert tips use seat size 19. This drill body is appropriate for general-purpose drilling in steel, cast iron, and similar workpiece materials in both high-volume production and precision short-run operations.

Installation Notes

Installation and tip changes should be performed by qualified machinists following the machine tool builder lockout and energy-isolation procedures before any tooling work. Ensure the straight-cylindrical shank is properly seated and clamped to the specified retention torque per the machine tool or toolholder manufacturer guidelines before operation. Through-coolant passages should be cleared and verified before mounting to prevent blockage at the insert tip. Do not exceed the rated maximum drill depth or feed rates for the selected insert grade.
