Iscar 3203329 Replaceable-tip Drill 0.295-0.311 in Weldon

Product Description

The ISCAR 3203329 is a replaceable-tip drill body from the SumoCham series, designed for precision holemaking in metalworking applications. It accepts a range of interchangeable drill tip inserts, allowing the body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 0.295 to 0.311 inches with a maximum drill depth of 0.44 inches. It features a 1/2-inch Weldon Flat shank for secure, anti-rotation clamping in compatible toolholders. Overall length is 2.76 inches. The through-coolant design delivers cutting fluid directly to the cutting zone, extending tip life and improving chip evacuation in deep or high-speed drilling operations. This tool is typically installed and operated by machinists and CNC setup technicians.

The ISCAR 3203329 is suited for production holemaking on CNC machining centers and drill presses where repeatable hole diameter and efficient cycle times are required. The replaceable-tip design is particularly valuable in high-volume environments where minimizing downtime during tip changes is a priority. Compatible insert styles include FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M, giving the operator flexibility in tip geometry selection based on workpiece material and application requirements.

Key Features

• Diameter range of 0.295 to 0.311 inches accommodates slight variation in tip selection
• Through-coolant design directs fluid to the cutting edge for improved chip removal and tool life
• 1/2-inch Weldon Flat shank provides positive anti-rotation engagement in standard toolholders
• Replaceable-tip system reduces tooling cost by allowing body reuse across multiple tip changes
• Compatible with seven insert styles: FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M
• Conforms to ISO 13399 tooling data standards for seamless CAM and tool management integration

Compatibility

Compatible insert styles are FCP, HCP-IQ, ICK, ICK-2M, ICM, ICP, and iCP-2M. The DCN A toolholder style designation applies. Designed for use in toolholders accepting a 1/2-inch Weldon Flat shank.

Installation Notes

Installation and tip changes should be performed by a qualified machinist following the machine tool manufacturer's lockout/tagout procedure before any toolholder work is performed. Ensure the Weldon Flat setscrew is properly seated against the flat on the shank to prevent rotation under cutting loads. Verify coolant passages are clear and flow is confirmed before initiating a cut. Follow the tip manufacturer's recommended torque procedure for the insert clamping screw using the appropriate ISCAR torx or hex key.
