Iscar 3200537 Replaceable-tip Drill 0.394-0.409 in Weldon Flat

Product Description

The ISCAR 3200537 is a replaceable-tip drill body from the CHAMDRILL series, designed for holemaking applications in metal cutting operations. It accepts IDI-SG and IDI-SK style inserts at seat size 10, allowing fast tip changes without removing the body from the toolholder. The drill covers a diameter range of 0.394 to 0.409 inches with a maximum drill depth of 1.18 inches and a 3xD depth-to-diameter ratio. Through-coolant capability delivers cutting fluid directly to the cutting zone, improving chip evacuation and tool life in demanding production environments. Licensed machinists and CNC operators are the primary users of this tooling.

This drill body is suited for production machining centers and CNC drilling operations requiring repeatable hole quality and quick insert indexing. The 5/8 inch Weldon Flat shank with a 0.625 inch shank diameter fits standard Weldon-style toolholders using the DCM toolholder style designation. With an overall length of 3.62 inches and a body length of 1.73 inches, this drill fits compact spindle setups while maintaining adequate reach for typical shallow-hole applications in steel, cast iron, and similar machinable alloys.

Key Features

• Accepts IDI-SG and IDI-SK replaceable insert tips at insert seat size 10 for fast, repeatable tip changes
• Through-coolant design channels fluid directly to the cutting edge for improved chip flushing and heat control
• Weldon Flat shank prevents rotational slippage under high-torque drilling conditions
• 3xD depth-to-diameter ratio supports stable, chatter-resistant cutting at the rated depth range
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems
• DCM toolholder style designation ensures straightforward holder selection and setup documentation

Compatibility

Compatible with IDI-SG and IDI-SK style replaceable drill tip inserts at insert seat size 10. Designed for use with DCM-style Weldon Flat toolholders accepting a 0.625 inch shank diameter.

Installation Notes

Installation and tool changes should be performed by qualified machinists following machine builder lockout and tagout procedures before accessing the spindle. Verify the Weldon Flat set screw engages the flat on the shank correctly and is torqued to the toolholder manufacturer specification. Confirm coolant passages are clear and through-coolant supply is active before starting the cut. Do not exceed the rated maximum drill depth of 1.18 inches without consulting ISCAR application guidelines for extended-reach setups.
