Iscar 3201743 Replaceable-tip Drill Through Coolant

Product Description

The ISCAR 3201743 is a replaceable-tip drill body from the SumoCham series, designed for holemaking operations in metal cutting and machining environments. The drill accepts interchangeable cutting-tip inserts rather than a brazed or integral cutting edge, allowing worn tips to be swapped quickly without replacing the entire tool body. It covers a drilling diameter range of 0.945 to 0.98 inches, reaches a maximum drill depth of 4.72 inches, and features a 1.25-inch Weldon Flat shank for positive drive and repeatable runout. Through-coolant capability delivers cutting fluid directly to the cutting zone, improving chip evacuation and tool life at higher feed rates.

This drill body is suited to production machining cells, job shops, and toolrooms running ferrous or nonferrous materials where hole quality and cycle time matter. The DCN-style toolholder body pairs with a standard Weldon Flat chuck or milling machine side-lock holder. The 5xD depth-to-diameter ratio makes it appropriate for moderately deep hole applications without the deflection risk associated with longer aspect ratios. Installation is performed by machining technicians and CNC setup personnel working on vertical or horizontal machining centers, lathes with live tooling, and dedicated drilling machines.

Key Features

• Replaceable cutting tip design reduces tooling cost per hole compared to solid-carbide drills
• Through-coolant bore channels coolant directly to the cutting tip for chip flushing and heat control
• Compatible with FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M insert styles at seat size 24
• Weldon Flat shank provides positive torque transfer and prevents pullout under load
• 5xD drilling depth ratio suitable for moderately deep hole applications
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

The 3201743 is compatible with FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M replaceable drill tip inserts at insert seat size 24. It belongs to the ISCAR SumoCham series with a DCN toolholder style and is designed for use in standard Weldon Flat chuck holders sized for a 1.25-inch shank.

Installation Notes

Installation should be performed by a qualified machining technician with the machine powered down and locked out per facility lockout/tagout procedures. Ensure the Weldon Flat set screw in the chuck engages the flat fully before applying cutting loads. Confirm coolant passages are clear and through-coolant pressure is set to the machine specification before running the tool. Follow insert manufacturer seating and torque guidance when fitting or swapping cutting tips.
