Iscar 3202512 Replaceable-tip Drill Weldon Flat Shank

Product Description

The ISCAR 3202512 is a SumoCham-series replaceable-tip drill designed for precision holemaking in metal-cutting applications. The drill body accepts interchangeable cutting tips, eliminating the need to replace the entire tool when the cutting edge wears. It covers a diameter range of 0.709 to 0.744 inches with a maximum drilling depth of 1.06 inches, and features through-coolant delivery to flush chips and manage heat at the cutting zone. The Weldon flat shank measures 1 inch in diameter, providing a positive anti-rotation grip in compatible toolholders. Overall length is 4.39 inches. Licensed machinists and CNC operators are the typical end users.

This drill body is suited for production and job-shop environments running vertical machining centers, horizontal machining centers, or CNC lathes with driven tooling. The through-coolant design makes it particularly effective in deep-entry cuts and in materials that generate significant heat or require aggressive chip evacuation. The DCN toolholder style designation aligns with standard modular tooling setups. Seat size 18 governs which cutting tip inserts are compatible with this body.

Key Features

• Replaceable-tip design reduces tooling cost compared to solid carbide drills of equivalent diameter
• Through-coolant capability improves chip evacuation and extends insert life in ferrous and non-ferrous materials
• Weldon flat shank provides secure anti-rotation clamping in side-lock toolholders
• Diameter range of 0.709 to 0.744 inches accommodates slight tip size variation within the seat 18 insert family
• SumoCham series body conforms to ISO 13399 tooling data standards
• Body length of 2.19 inches and shank length of 2.20 inches contribute to a balanced 4.39-inch overall length

Compatibility

Compatible insert styles for seat size 18 include FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M cutting tips. Toolholder style is DCN. The body is part of the ISCAR SumoCham platform.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool-change interlock is engaged before mounting or removing the drill body. Secure the Weldon flat shank in a side-lock holder torqued according to the toolholder manufacturer specifications. Inspect the insert seat and cutting tip seating surfaces for chips or contamination before each tip change to maintain concentricity and prevent premature wear.
