Iscar 3346595 Replaceable-tip Drill 4.5-4.9mm Dcn Series

Product Description

The ISCAR 3346595 is a DCN-series replaceable-tip drill designed for precision drilling applications across a diameter range of 4.5 to 4.9 mm. The body is constructed from steel and accepts ICP-style replaceable inserts, allowing the cutting tip to be swapped without removing the holder from the machine. Maximum drill depth reaches 14.16 mm, supported by a 6 mm straight-cylindrical shank. Overall length is 59.65 mm. Through-coolant capability delivers cutting fluid directly to the cutting zone, reducing heat buildup and extending insert life in production drilling environments. This tool is installed and operated by machinists and CNC tooling technicians.

The 3346595 is suited for use in CNC machining centers, drill presses, and turning centers where consistent hole quality across small-diameter bores is required. The replaceable-tip design supports high-volume production runs in metalworking shops, tool rooms, and job shops working with steel and similar materials. The DCN toolholder style integrates directly with compatible ICP inserts for repeatable runout and straightforward tip changes at the machine.

Key Features

• Diameter range of 4.5 to 4.9 mm accommodates varied bore size requirements with a single holder
• Through-coolant design channels fluid to the cutting edge for improved chip evacuation and thermal control
• ICP replaceable insert compatibility allows fast tip changes without disturbing the toolholder setup
• Steel body construction provides rigidity and durability in continuous drilling operations
• 59.65 mm overall length and 6 mm straight-cylindrical shank suit standard collet and chuck systems
• DCN series toolholder style ensures consistent insert seating and repeatable hole geometry

Compatibility

Designed for use with ICP-style replaceable drill inserts in the DCN toolholder series. Verify insert style and shank diameter against machine spindle and collet specifications before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the toolholder. Confirm the 6 mm shank is properly seated and clamped to the torque specifications required by the workholding system in use. Activate through-coolant supply before initiating the cut to prevent thermal damage to the insert and workpiece.
