Walter 7508852 Replaceable-tip Drill 17-17.99mm 3/4in Shank

Product Description

The WALTER 7508852 is a replaceable-tip drill body designed for solid drilling operations in metalworking and machining environments. It accepts a diameter range of 17 to 17.99 mm and achieves a maximum drill depth of 54 mm, operating at a 3xD depth-to-diameter ratio. The tool body is constructed from steel and features a 3/4 inch straight-cylindrical shank for secure toolholder mounting. Through-coolant capability is built in, supporting efficient chip evacuation and thermal control during high-feed drilling cycles. This is a body-only component; cutting inserts are purchased separately.

The 7508852 is suited for CNC machining centers and drill-specific setups where replaceable-tip tooling reduces downtime versus brazed or solid carbide drills. Its Series D4140 toolholder style and 68 mm flute length make it appropriate for production drilling in steel, cast iron, and similar workpiece materials. Machinists and toolroom technicians working in job shops, aerospace manufacturing, and general metalworking are the primary users of this tool body.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before mounting or removing the drill body or inserts. Verify shank-to-toolholder interface cleanliness and proper insert seating before initiating any cutting cycle. Do not exceed the rated drill depth or depth-to-diameter ratio specified for this tool body.
